reflex to be realized through temporary connection, i. e. this is a
physiological phenomenon that has definite structural foundations,
and certainly the mechanism of conditioned reflexes can be disclosed
by physiological methods of investigation (see Pavlov, 1932, 1931.3
Beritashvili, 193). On the other hand, in the opinion of Walter,
this is. only a question of technical refinements in order to be able
to observe in the fora of electrical discharges ideas that arise in
the brain of ran (Walter, 1952) of course, this notion is not
correct. Thinking. cannot be expressed as adequately ideal in
biaelectrical potentials of brain tissue and cannot be reduced to them,)
Apparently the oscillographie method giving an opportunity for
direct observation of the nerve processes must play an incomparably
greater role taan the method of extirpation and the method .f
electrical stimulation, even in case it is lilted by the use of
bioelectrical phenomena as such in the objectives of investigation of
the essentiality of the nature of these potentials, i, e. whether
temporarily it is not to be regarded as the physicochemical bases
of these potentials, being put wide. indicative of this are the
large-scale discoveries made during the last 25 years, after the
well-known paper of Sarnoilov (1930), in the field of the physiology
of the spinal cord, as well as the quick accuniulation of facts on

having set as my purpose the use of the oacillographic thud
for study of conditioned-reflex activity, I resolved to carry out a
whole preliminary series of investigations in conditions of pointed,
lingering eri,rnents on narcotized and on normal anim~cls and to
study bioelectrical reactions of the cerebral cortex arising during
i.ts direct electrical stimulation and at stimulation of the receptors
or the corresponding nerves. These reactions have been insufficiently
studied even in conditions of ingenious experiments, and on horn l
animals they have not been able to be recorded until very recently.
A$ to the origin and physiological importance of these reactions,
there have been a number of hypotheses, often contradictory. It is
necessary to think that only after solving these problems will it be
passible to proceed to osciliographic liwestigation of' the eonditioned-
reflex activity of the cerebral cortex.
The work presented is experimental, and little space is assigned
to conaldera tlon8 not based dir ec: tiny on facts, No _ goal has been set
to give a .systematic literary survey of all that has been donne in
the sphere of the electrophysiology of the cerebral cortex. Special
attention has been allotted to clarification of certain complex,
debatable questions. Although each cycle of the investigations issued

unified under a common designation. In Part I the results are

1. Regional Excitation and Local Potential
The School of Physiology, Leningrad University, contrary to
the prevalent principle o.f "all or nothing" has permitted various
modifications by which the state of excitation can be expressed
(see Ukhtomskii, 193940)., According to the concepts deieloped in
this schools. excitation does not obligatorily make off in the form

of a rave from the region of its origin. In certain conditions it
y keep to the place of origin for a more or less .low time in the
form of a fined, regional excitation, ready to flare up in the fora
of an excitation wave (Ukhtonuskii, 1927, 1932, 19394O). Yet
Chagovets (1906) for purely theoretical reasons recognized the need
of a preliminary regional potential for the arising of spreading
excitation. Erlanger and 0asaer in 1937 wrote that the electrotanic
potential is a certain, unique electrical phenoinon which precedes
(at electrical irritation of a nerve) the current of spreading
excitation ("peak").
The electrotonic potential that Arises at electrical irritation
of a nerve is connected, as supposed, with the capacitative properties
of the fibers (danger and Gasser, 1937; Eodgk n, 1930. The
electrical potential quickly (after .50 microseconds) reaches a

should 'be added that it grown in proportion to the intensity of the
stimulating current, that at reversal of theterminals of the
stimulating current it cnges its sign, that temperature changes
hardly affect it, and finally that it radiates vith logarithmic
decree nt along the nerve fibers.
The local potential of the nerve fiber was recorded in 1938
'by hod in. He was unable to discover the local bioe.lectrical
potential in the nerve as a thole because of the very strong

When the amplitude of the local potential reached 15~20
mi fivolts (i. e. 0.3 of the current amplitude of the spreading
excitation), then it overincreased into an excitation current
that was expressed in the arising of a two-phase potential (1o'60
millivolts); the excitatiaia spread along th4fiber . passing
under the first deflecting electrode, reached the second (Fig. 1).

At observation of the bloeleetrical pbenomena in the central
nervous system ate run into two phenomena stipulated by the local
potentials in the neuronic elnts. '
When a local potential arises in the. cells, then an electrotonic
reaction arises, first in th?ae fibers which are axons of the activated
neurons and Secondly in those fibers which terminate with synapses at
these neurons. The electrotonus spreads along the fibers with decrement
and during certain conditions can be detected (fro the roots of the
spinal cord) at a distance of up to 10 man. in the form of a negative
bloelectrical potential. Thus, the local potentials of the nerve ceU.e
can stipulate the phenomenon of the physiological electrotonur of the
nerve elements.
aowever, there were, also observed electrical phenomena of another
character that did not attract to themselves special attention,. namely
at the arising of regional excitation in the cell from the axon a

in the outer geniculate body at the level of the layer of cellular
bodies a positive potential at this tSine was discharged from the
electrode found at the level of the axons of these cells (Bishop and
O'Leary, 193) ? perhaps these electrical phenomena which we still
run into are phenomena essentially like secondary electratonic changes,

 the pert-electrons (sic: -sbould be peri?electrotoni') (Tvedenski.t,
1920), (Footnote: Jccording to the data of Beritov and, Roitbak (19 ),
in the electrotonic and pari.electrotonio spheres of the nerve trunk
potentials of opposite sign arise. For ex*nlple, at completion of a
descending current at the cathode a negative potential is registered
that gradually weakens at retauing the deflecting electrode froni the.
thud, F inaUy, at a certain distance it stops being registered.
If too the electrode is removed still further, then at completion
of the current a positive potential of considerable amplitude is
registered, and this sphere of the riwelectrotonus extends for a
considerable distance.) If this is so, then it is possible to eke
the following conclusion: local potentials arising during regional
excitation of nerve cells can stipulate electrotonic and peril
electretonia phenomena in neuronic elents.

The first commection between. the data of oscillogr phy and the

From the anterior rootS, i.e. from the axons of the motor
neurons slow electrotOflie potentials are registered that have been
atipulatedd by the local potentials of the motor neurons. Apparently
the electrotonic reaction of each axon is the consequence and
expression of the local pGtentiel, namely of the cell from which
it took its beginning.
When the motor neurons are activated only by excitation
impulses from the direct posterior-root collaterals (far instance,
at stimulation of the muscle nerve or at threshold stimulation of
a mixed nerve or of a posterior root), then the following electrical
effect is registered from the anterior root: a certain time after
the stimulation artefact a quick potential arises, after which a
negative slow potential follows. The initial quick potential is
the consequence of a relatively synchronous discharge of afferent
impulses and expresses the excitation currents of the presyna'ptic
fibers and of the synaptic tern11n is of direct posterior-root
collaterals,in the anterior horn, being electrotonically carrie':'%
along the anterior-rant fibers (Beritov, l96, 19k9)-: The negative
slaw potential expresses local potentials in motoneurans, erieing
below the synapses of the direct posteriori-root coUaterals.
A large number of synapses are on each rnotone on of the
anterior horn. After 3.00 of them are counted vn the body of the

moton~urcrn of the spliml cord of cat (CholakaskLvili, 193) . Their
everag size is 1 micron (a, r and Barr, 1950). Ppparently not
devoid of physiological importance is the fact that synapses are
agreed on the surface of the motoneuran in the form of separate
foci that are i their nature "the synaptic fields" of the cell
(Zurabashvili, l91.7).
Excitation of one synapse is insufficient to arouse.the cell
and to be discharged to its axon, It is likewise assinid. that
insufficient for this is excitation of severed synapsea that remain
far from one another (Lorente de lid, 1938). excitation of a
motoneuron and discharge to the axon proceed when afferent impulses
corm simultaneously to a whole group of synapsee arranged. on the .
body of the cell in a certain proximity to one another. Otherwise,
only re.ona1 excitation arises in the cell, with a local potential
corre ending to it, as occurs in.a nerve fiber at subthreshold

1. Concerning Long I onfluctuating Bioelectrical Potentials
As far back as in early invostigetions of the bioelectrical
phenomena of the central nervous system, carried out with the aid
of a lvanorneter, sirrdi1ar potentials were reported. Mislavskii
(189, 1900), at the discharging of current from the posterior
roots of the spinal cord of frog observed long nonfluctuating
biocurrents during tetanic irritation of the sciatic nerve and
at adequate sttulatians of the skin.
lov and Lapitskii recorded during discharge of currents
from the spinal cord (1 electrode on the surface of the lumbar part
of the spinal cord, on a crosswise section) the following phenomena:
quick fluctuations following the rhythm of stimulation of the sciatic
nerve up to 100 per second, were placed on a backiround of a slow.
. nonfluctuating potential, the amplitude of. which was increased with
increase of frequency of stimulation up to x.00 a second and reached
1 millivolt (Delon and Lapitskii, l93), In 1 i.g. 1, D is presented
the oecillophic recording of a nonfluctuating biopotential,
registered from. the posterior root during tetanic stimuiation of the
sciatic nerve.

Bioeleotrical Potentials Arising in the Cerebral Cortex During
Direct Electrical Stimulation of its Surface
The cerebrum differs from the spinal card by, among other things,
the fact (and this has drawn the attention already of the first investi>
gators of the electrical phenomena of the central nervous system) that
during the absence oi' special, stimulations and during deliberate
exclusion of exteri stimulations from the cerebrum and from the
cerebral cortex, in particular, certain electrical fluctuations are
discharged. 1vidently the so-called "spontaneous" electrical activity
of the cerebrum is a consequence and an expression of the greater
excitability of its nerve elentsg in comparison with the spinal
neurons. Apparently various negligible e.ter n1 gnd internal stiniu1a>
tions are capable of causing excitation of the neuron that compose
the . nerve centers of the cerebrum. This should jrticularly be
referred to cortical neurons possessing highest excitability. We
shall come back to this question again.
As for the specially provoked bloelectrical reactions of the
cerebral cortex, this question too comprises the nMn content of the

present Investigation. The following are experimental possibilities
for excitation . of the cortical neurons by means of nerve impulses
the source of which can be determined,
a) Excitation of afferent systems of the cortex by adequate
stimulations of the receptors or by electrical stimulation, of the
corresponding sensory nerves.
b) Excitation of the system of callosal fibers by electrical
stimulation of the cortex of the opposite hemisphere or of the corpus
callosum itself. It should be noted that Ianilevskii was the first
to observe bloeleetrical reactions In the cortex at stimulation of
the cortex of the opposite hemisphere (1891)?
c) Excitation of the system of fibers 'in layer I of the cortex
by direct electrical stimulation of the surface of the cortex.
d) Fir11y, it is possible 'to send antidramically excitation
impulses into the pyramidal neurons of the cortex durIng stimulation
of the pyramidal tracts (Woolsey and Chang, 1947)
The first two possibilities were used during a study. of electrical
phenoa in the cortex even In the last century an4 at the beginning
of this 'century. With the development of an oscillagraphic technique
quite a large number of similar investigations appeared (see Chapter Iv).
In world literature until recently there were only 2 articles
relative to the bioelectrical reactions of the cerebral cortex that set

the clarification of certain questions of the phology of the cerebral
cortex. There is nothing unexpected in this, because with the aid of
the method of the electrical st3 ].stun tiny. important facts have been
obtained which have not lost their aignificance (Fritsch and 11itzig,
1870; Vvedenshii, 1$97; htomsk.il, 1911, et al,). By the way, to
Pvlov belongs the idea of studying the action of direct electrical
stimulation of the various points of the surface of the cortex for
effects of conditional stimulants (1926).
A description will be given further on of the numerous
axperiu nts with electrical stimulation of the cerebral cortex and
of the registration of the bioelectrical potentials thereby arising,
beginning with cotrativell simple experiments and ending with those
quite camiple$ in set-up and results.
The experiments were made on cats under nembutal narcosis
(210 mg. per kg, of weight). - The operation consisted of `dosing.

to poisoning; after this the area under the stimulation electrodes
was poisoned with a Q,5% solution of strychnine; the strychnine was
removed after 3 minutes. D is the effect of the same stimulation 3.5
minutes after application of the strychnine to the brain under the
stimulation electrodes. E is the effect ref the same stimulation 15
minutes after the. recording of I), Indication of 0,3 millivolt for A,
of 0,6 millivolt for C,). In the experin nts of eritov and 1oitbsk
(1950b) on apirl cord of frog it was discovered that at relatively
great concentration of strychnine (general or local poisoning) it
is possible to observe two stages of its effect: at first, the
posterior and anterior root potentials attenuate, and only after
several minutes do they begin to intensify. Thus, weakening of the
cortical negative potentials after strychnine poisoning should be
ascribed to its parabiotic action on the neuron elements. Histological
investigation of the part of the cortex subjected to poisoning by
saturated solution of strychnine showed drastic morphological hanges
of the cortical neurons (s. Beritashvili, 1952). In connectian with
what has been mentioned above, it is possible to set forth the following
fact obtained by .Chung (1951) ; the negative potential ac usted to be
provoked 8 man, after a strip of paper saturated with a solution of
cocaine was placed on the cortex between the stimulation and the

Schematic depiction of the neurons of layer Ii of the darter and of

neurons of layer II of the cortex. 1 is a neuron with ascending
axon. 2 is a neuron with horizontal axon. 3 is a neuron with
descending axon and collateral returning into layer I (star cell).
The scheme was composed an the basis of certain histological data.)
On the basis of certain histological information mentioned
above about layer Ii of the cortex it is possible to make the following
conclusions:
1. During excitation of. the system of fibers of layer I
excitation of the cells of layer II can occur, because in layer II
there are numerous coilaterals of the fibers of layer I.
2. During excitation of the cells of _ layer Ii ietivation can
occur of the top dendrites in layer I, because among the cells of
layer II are cells with axon ascending into layer I, which take on
there a horizontal direction and give fort many Collaterals. In
addition, the axons of the star pyramids give forth collaterale into
layers I and II.

after a supplementary negative. potential (Fig. 28, A and B).

According to Cbang, preceding a supplementary negative potential
is a positive one, i.e. response to stimulation a negative potential
arises that passes over into a positive one, after which a second
tive. fluctuation follows. This actually can occur (see Fig. 15),
but this is not the rule: suppler ntaary negative fluctuations can
arise 'without the preliminary first negative potential having changed
to positive. (see Fig. 22).
Finally, a positive fluctuation (FIg. 23, C) can precede the
initial negative potential, which Ong (1951) also paints out.
In the njorIty of cases after the negative potential a low
positive defection is observed of considerable length. It is
difficult to say whether it always expresses activation of the
elements of the deep layers, since it is observed also during deep
narcosis. Perhaps this Is the analogue of the subsequent positive
potential after regional excitation. Such resultant potentials
arise, as already said, in the mtoneurons.
The following data regard the positive potentials that arise
at stimulation of the surface of the cortex.
1., In experiments on isolated strip of cortex the following
facts were established. When the cortex was not narcotized, then
in respvnae to a shock. off' stimulation applied to the surface of the
cortex a brief negative potential arises ( 3? milliseconds), after

With very light narcr~sis (Fig. 311.) the activity begins to
spread from the point being stimulated not only to greater distances
but also without appreciable decrement: the amplitude of the potentials
at a remote point can be even greater than nearby (oec. A and B).
Yurthermore, complex effects arise, the character of which shows that,
together with impulses from fibers of layer I by direct activation of
the top dendrites, additional activation of them occurs from the
intermediate cortical neurons, the various completes of which are
included in the activity at a different time. A sma7.l positive
fluctuation precedes the negative potential at point L2. However.,
this is evidently an expression of polarization, since this fluctuation
disappears at change of direction of the stimulating current, ilhereas
the character of the negative potential is not changed (oso. it).
Sometimes just one shock of stimulation causes prolonged
rbrthmicai aftereffect.. In the aftereffect the activity spreads
