Through the clinical study of brain tumors, we had a conclusion on the cerebral mechanism which influence the sacral center on the micturition. That will be described as follows:
1. The frontal lobe has something to do with inhibitory function of the micturition especially the left frontal lobe seems to be very significant.
2. It is very doubtful that there is an inhibitory factor in motor area.
3. The paracental lobule seems to have an inhibitory function, incontinence, however, may not appear unless both lobules are invaded.
4. The possibility of the existence of an inhibitory center in the cingulate gyrus is extremely doubtful. It is out of our consideration that there exists, at least, an inhibitory center on the anterior cingulate gyrus.
5. It is also doubtful that there is an inhibitory or an accelerating center in the diencephalon.
6. The upper part of the mesencephalon appears to be no important center of micturition.
7. It is clear that there are some accelerating center of micturition in the area of lower mesencephalon and upper medulla with the pons as its significant site (Fig. 3).

The experimental subjects consisted of 35 curarized adult cats. With the use of superfine microelectrodes, the single neuronal activities of the principal nuclei of the amygdala were picked up and the reactions to the electrical stimulation given to the temporal tip, midbrain reticular formation, and nonspecific thalamic nuclei were observed.
By the stimulation of the temporal tip, excitatory as well as inhibitory reactions were obtained. In some cases the reversal from inhibition to excitation either during or subsequent to the stimulation was observed. It came to be clear, from the intracellular recording, that EPSPs, the spikes superimposed on them, and IPSPs were generated by each shock, and that both excitatory and inhibitory synaptic contacts are present in one and the same neuron.
With the repetition of the stimulation IPSPs decreased while EPSPs increased; and especially by high frequency stimulation, the membrane potentials were kept above the critical level, and successive spikes were generated. This was suggestive of the reversal mechanism from inhibition to excitation.
By stimulation of the midbrain reticular formation, both excitatory and inhibitory reactions were recognized. The intracellular recording showed the long lasting depolarization due to the summation of EPSPs with the increase of spike firing.
By stimulation of the nonspecific thalamic nuclei both excitatory and inhibitory reactions were also observed, while that of the specific nuclei induced no response. The intracellular records revealed generation of EPSPs and IPSPs. The relation between spike responses and the postsynaptic potentials was discussed.
With reference to the same neurons, stimulations were given to the temporal tip and midbrain- and thalamic reticular systems and consequently the existence of the convergence of the synapses of projections from these regions was ascertained.
When the reactions occuring due to each stimulation of these regions are of the same kind, they were intensified by the combined stimulation; when they were opposite, the reaction caused by the stimulation of temporal tip appeared dominant in most cases.

Through bilateral extensive destruction of hippocampus in several groups of young albino rats of the same partus and sex, we can recognize changes in the sexual cycle and behavior, while disturbances in food or water intake and in the growth rate of these experimented infant animals were not so remarkable as compared with the same experiments on the amygdaloid region.

On conditioning hippocampal recruiting responses, the authors got findings similar to that obtained in the case of conditioning with the aid of intermittent photic stimulation or electrical stimulation of some thalamic structures:
1. In the early stage of conditioning, generalized evoked potentials followed by hippocampal arousal pattern and sometimes orienting reflexes were induced by CS. In the later stage of conditioning, this arousal pattern and behavioral change disappeared, when conditioned characteristic waves could be witnessed in the cortices. And conditioned characteristic waves appeared mainly in the neocortical structures. In this case conditioning seemed to be a little difficult to be established, while it was not easily extinguished.
2. In the couse of conditioning, spindle waves were often evoked during or immediately after UCS and later on they could be seen during CS. These spindles were supposed to be similar to sleep spindles because of their wave form, frequency, sites of appearence and behavioral changes dropping the head, closing the eye and relaxing neck muscles).
3. It was worthy of note that these animals often showed behavioral changes similar to experimental neurosis in the course of electrical conditioning of hippocampal complexes.

Electrical activities of the neo-, paleo- and archicortex with their related subcortical nuclei were studied in unanesthetized curarized cats, and the following results were obtained.
1.Dissociation of the activity level between neo-, paleo- and archicortex appeared under some animal conditions or influences of pharmacological agents.
2. Comparison of the effects of electrical stimulation of the posterior part of the hypothalamus and midbrain reticular formation revealed that the activating effect of the posterior part of the hypothalamus on the hippocampus was stronger than that of midbrain reticular formation and effect of the posterior part of the hypothalamus on the neocortex was weaker than the reticular formation.
3. Anterior part of the hypothalamus had the specific activating effect upon the electrical activities of the paleocortex and its subcortical nuclei (amygdala and olfactory bulb).
4. Hippocampal arousal pattern could be desynchronized by high frequency electrical stimulation of the anterior part of the hypothalamus, septal area and amygdaloid nucleus.

The functional relation between the olfactory bulb and the subcortical activating system was investigated in the curarized rabbits. The intrinsic and the induced waves of the olfactory bulb were suppressed by high frequency stimulation of the mesencephalic reticular formation and the posterior hypothalamus. In contrast to this, anterior hypothalamic stimulation mostly resulted in augmentation of both kinds of electrical activity, but in some cases only the intrinsic waves were enhanced with the induced ones suppressed. These findings were discussed in comparison with those of the previous investigators.

Two types of the so-called hippocampal arousal waves were reported in relation to the dog's behaviors. The one, hippocampal rhythmic wave-S, occurred only after sleep pattern spontaneously or by stimuli, during the appearance of which the animal kept continuously a sleeping posture but showed a few localized twichings of eyelids, conchae, vibrissae, facial muscles etc. and frequently rapid movement potentials of eyeballs. The other, hippocampal rhythmic wave-A, was seen in a short train during wakefulness, accompanying some actions, i.e. head-turning, sniffing, searching on the floor etc. The characteristics and interrelationships of these waves were discussed.

On the study of the behaviors of neurons during the appearance of evoked potential or seizure discharge in the Ammon's horn produced by repetitive electrical stimulation, the following results are obtained:
1. The unit discharges are roughly classified into three groups of 1) complete synchronous type, 2) incomplete synchronous type, and 3) indifferent type according to their synchronization with response-wave and seizure discharge, and in response-wave and seizure discharge alike, the percentages of the unit discharges in each type are approximate. Further, according to discharging frequency of unit spike, we get facilitation type, inhibition type, and indifferent type.
2. On the second positive phase of the response-wave caused by repetitive electrical stimulation, there arise the gigantic spikes (G-spike) of 3-5msec. duration, and they appear as a negative-positive spikes at a shallow layer near the alveus, while as positive-negative biphasic ones near pyramidal cell layer. They arise spontaneously at the seizure discharge and show an extremely close relation with seizure.

1. The effects of chlorpromazine on the afferent and efferent pathways of the hippocampus were investigated and compared with that of hexobarbital sodium.
2. Chlorpromazine and hexobarbital sodium suppressed the hippocampal seizures induced by repetitive stimulation of the fornix.
3. Single shock response or post-tetanic potentiation recorded from the hippocampus following single or repetitive stimulation of the fornix were not depressed by chlorpromazine.
Hexobarbital sodium suppressed the development of potentiation without any effect on single shock potential in this pathway.
4. Chlorpromazine and hexobarbital sodium selectively depressed posttetanic potentiation following reptitive stimulation of amygdala without affecting single shock potential.
5. Effects of these drugs on the efferent pathway from the hippocampus to hypothalamus were investigated. Chlorpromazine had no significant effects on this pathway. Hexobarbital sodium suppressed the development of potentiation of the hypothalamic response following repetitive stimulation of the hippocampus without notable effect on single shock response.

The potential pattern and topographical arrangement of vagal neurons in the medulla of the decerebrated cat were studied by the unit response analysis, employing microelectrodes.
1) Stimulation of the vagus nerve between the ganglion nodosum and the ramification of the recurrent nerve evoked the potential in the following regions in the medulla; i.e., the area in the vicinity of the solitary tract, the triangular nucleus of the vestibular nerve, the nucleus of the spinal tract of the trigeminal nerve, and the ambiguus nucleus. By the use of double stimulation method, it was concluded that the responses obtained in the vicinity of the solitary tract, trigeminal nucleus and triangular nucleus of vestibular nerve were due to orthodromic conduction of impulses and those in the ambiguus nucleus due to antidromic one.
2) Conduction velocities of these afferents ranged from 18 to 92 meters per second. Spontaneous discharges synchronous with respiratory cycle or discharges induced by a traction of the lung were frequently encountered in vagal units located in the ventral part of the nuclei of the solitary tract.
3) Cajal's commissure of the vagus nerve was the only portion where responses could be obtained to stimulation of the contralateral vagus nerve.
4) The responses to vagal stimulation which were antidromic in nature were encountered in the caudal part of ambiguus nucleus. Conduction velocities ranged from 40 to 110 meters per second, the maximal value of responses being 500μV in magnitude. Some units located medially in this area displayed often impulse discharge synchronous with respiratory cycle.
5) When the vagus nerve was stimulated in the thoracic cavity, evoked potentials could be obtained only in the vicinity of the solitary tract and triangular nucleus of vestibular nerve.
