摘要:

SummaryThe course of the spino‐olivary tract was followed by theMarchimethod on adult cats in which Cl, C2, C3, C8and L3of the spinal cord were partially cut by means of small knives, with special reference toOgaiva'striangle fasciculus which was reported byOgawain intact mammals as corresponding toHelweg'striangle fasciculus in human material. The survival time was 17 to 22 days after operation. The results obtained were as follows:1) The spino‐olivary tract ascends bilaterally and diffusely through the ventral layer of the ventral funiculus below C4or C5, Above about C4or C5, this tract is gradually collected in the region underneath the pia mater along the ventral margin of the ventral funiculus. At C1and C2, the spino‐thalamic tract joins the region of the spino‐olivary fract, two tracts intermingling and forming together a fiber bundle consisting of finer fibers than those surrounding them. The bundle is now recognizable in intact material as the triangle fasciculus. At the level of the pyramidal decussation it lies just lateral to the pyramis, and at the olivary level mainly medial to the hypoglossal root and ventrolateral to the inferior olive. The spino‐olivary tract terminates in the dorsal and medial accessory olive. Our observations indicate that most of the spino‐olivary tract takes the course mentioned.2) The opinion ofCajalandBrodal et al.that the spino‐olivary tract is formed of collaterals is unacceptable as far as our observations reach.3) The difference that the triangle fasciculus in cat stands in connection with the accessory olivary nuclei, while the same in human material connects with the main olivary nucleus, must be worth of speci

摘要:

SummaryThe authors examined about 300 children within 10 days of their third birthday from somatic as well as psychological point of view, and found a tendency that the smaller index ponderalis which the authors employed as a crude indicator of better somatic development, is associated with better social, and functional (intellectual and motor) development.

摘要:

SummaryCortical photic driving responses induced by intermittent flicker (2˜40/sec.) were observed in unanesthetized cat preparations, immobilized with succinyl‐cho‐line‐chloride and maintained on artificial respiration. Effects of arousal stimulation upon the photic driving response were chiefly examined. These resulted in:1) Photic driving responses were influenced by arousal stimulation. Amplitude, regularity of waxing and waning and appearance of harmonic components of the responses were modified by arousal stimulation.2) Effects resulting from arousal stimulation upon photic driving response were variable in relation to frequency differences of the cortical driving response. By arousal stimulation, lower cycle driving responses were inhibited but higher ones were facilitated.3) Second harmonic components of the driving response were often facilitated with the arousal stimulation. And it was observed that cortical fundamental photic driving responses were altered in the second harmonic photic driving responses by arousal function.4) Hihger cycle photic driving responses (30˜40/sec.) were only recorded under arousal condition while the critical fusion frequency for cortical photic driving was heightened by arousal stimulation.5) Strong arousal stimulation was useful in reappearance of photic driving response even in deep anesthesia.6) Lower cycle photic driving response was similar to recruiting or augmenting response and was differentiated from higher cycle photic driving response from the view points of the influence of arousal stim

摘要:

Summary1. At the superior mesencephalic level a small part of the medial forebrain bundle sweeps dorsalward, following the fibrae rectae, to enter the ventral part of the central gray substance. Another small part of the bundle crosses and reaches the opposite region of the medial forebrain bundle.2. The most massive root of the medial forebrain bundle in rabbits curves steeply dorsalward at the caudal level of the interpeduncular nucleus and, after passing through the medial longitudinal fasciculus, terminates in a confined region of the central gray substance just caudolateral to the trochlear nucleus and around the root of the trochlear nerve. The same region of the contralateral side also receives a lesser amount of degenerating fibers, most of which cross through the regions dorsal and ventral to the medial longitudinal fasciculus. Such a type of termination of the medial forebrain bundle can be observed remarkably in cases with lesions in the olfactory tubercle and lateral preoptic region, less remarkably in the case with a lesion in the anterior part of the amygdaloid body and very few, if any, in the case with a sucked cortex. The medial forebrain bundle in a cat, however, can be traced only to the tegmental region ventrolateral to the medial longitudinal fasciculus.3. Axons degenerated by lesions in the olfactory tubercle, lateral preoptic area and anterior part of the amygdaloid body terminate via the inferior thalamic peduncle and the lateral part of the thalamic medullary stria in the lateral habe‐nular nucleus. A moderate number of degenerating axons in the lateral part of the medullary stria terminate in the dorsomedial part of the nucl. medialis medi‐us(Ando)after traversing the habenular nucleus and the original part ofMeynert'sfasciculus. A small, but definite number of degenerating axons in the inferior thalamic peduncle descend, without joining the medullary stria, through the medial part of the thalamus and enter the ventromedial part of the nucl. medialis medius from the ventromedial aspect of this nucleus. Such a type of termination of degenerating axons in the nucl. medialis medius can be remarkably seen in cases with lesions of the olfactory tubercle and preoptic reg
