TL;DR: Input-output neural organization of single thalamocortical neurons in the ventrolateral nucleus of the thalamus was investigated using an intracellular recording technique in the anesthetized cat, indicating that the cortical arbolization of single T-C neurons is very wide and the number of these neurons with widely divergent projections is considerably large.

TL;DR: Topographic organizations of amygdaloid afferent fibers to various subdivisions of the hypothalamic nuclei are discussed and compared with other anatomical studies on these connections.

TL;DR: A significant loss of binocular cells was consistently found in the visual cortex of mature animals which had monocular vision for only 12 h dispersed over 6 days (2 h a day, otherwise kept in the dark) in combination with concurrent LC stimulation, interpreted as indicating that endogenous NA released from NA terminals restored susceptibility to monocular sight in the mature visual cortex.

TL;DR: Not only do more prefrontal neurons respond phasically to visual stimuli in the Cue and Response Periods or to reward or trial end in ITI, and become activated before lever release, but also they become active tonically in thecue, Response and ITI Periods.

TL;DR: It was concluded that at least a portion of the convergence of the dentate and the interpositus inputs occurred at the level of the ventrolateral nucleus of the thalamus.

TL;DR: It was found that Purkinje cells in the H-zone consistently changed their simple spike responses to head rotation in parallel with the adaptive HVOR gain change, consistent with the hypothesis that the flocculus Purkinji cells adaptively control the HVORN through their simple Spike activity under influences of retinal error signals conveyed by visual climbing fiber pathways.

TL;DR: Projection areas in the cerebral cortex from tongue nerves were investigated in anesthetized macaque monkeys and the prominent projection from the chorda tympani and glossopharyngeal nerve branch, containing taste fibers, to this area suggests its involvement in taste sensation.

TL;DR: The cerebellar flocculus was mapped with local stimulation techniques in alert pigmented rabbits and a restricted area specifically related to eye blinking was found in the rostroventral area of theFlocculus.

TL;DR: Xenopus oocytes injected with messenger RNA extracted from rat brain are induced to acquire a variety of neurotransmitter receptors and voltage-operated membrane channels, and there appear to be two classes of chloride channels one of which requires intracellular calcium to open.

TL;DR: The data suggest that the ARCN neurons of aged female rats still retain plasticity to react to deafferentation under influences of estrogen.

TL;DR: The results suggest that horizontal canal signals are conveyed to ipsilateral medial rectus motoneurons by two separate groups of vestibular nuclear neurons which may play different roles in the vestibulo-ocular reflex.

TL;DR: Stimulation of the whole oral cavity with four basic taste stimuli produced smaller mean response magnitudes in these thalamic taste neurons than in the parabrachio-thalamic (P-T) taste relay neurons.

TL;DR: The implantation technique described by Mori et al. has been modified for the implantation of crystalline wheat germ agglutinin-horseradish peroxidase (WGA-HRP) complex and it appears that both projections are topically organized.

TL;DR: The results indicate that sensitivities of the PFC neurons to ACh, NA and DA are not uniform between cortical layers, suggesting that each of these substances may predominantly influence the neuronal activity of particular layers of the monkey PFC.

TL;DR: A single dose of horseradish peroxidase polyacrylamide gel was injected into the head of the caudate nucleus in six macaque monkeys, and labeled cells were found abundantly in the rostral portion of the ipsilateral claustrum.

TL;DR: As a step toward elucidating the tectal-controlling functions for generating the prey-catching motor pattern, electrically-evoked "snapping" by means of stimuli applied to the optic tectum was analyzed using electromyographic methods in freely-moving Japanese toads.

TL;DR: The present results add further evidence to support the importance of the blockade of N-methyl-D-aspartic acid receptor-mediated events in the suppression of seizure activity.

TL;DR: It is suggested that this pupillo-constrictor area overlaps or lies in close proximity of a part of the region in PMLS area related to lens accommodation, in which unit activity temporally related to Lens accommodation was recorded and from which lens accommodation was evoked by electric stimulation.

TL;DR: Findings suggest that amino acid neurons could be involved in Alzheimer-type dementia and taurine and gamma-aminobutyric acid in the ATD brains were significantly lower in the inferior temporal cortex.

TL;DR: Electric stimulation at the nodulus and uvula of the cerebellum with a train of 5-10 pulses caused a marked depression of the renal sympathetic nerve activity, which caused a transient reduction of systemic blood pressure.

TL;DR: It is suggested that the decreased responses of the adrenal nerve during repetitive electrical stimulation of A afferent nerve fibers are attributable to summation of both the early depression and post-excitatory depression evoked by single shock stimulation, while the increased responses during repetitive stimulation of D-reflexes of spinal origin without clear depressions.

TL;DR: The specific [3H]nicotine binding was first detectable on day 16 of gestation and it increased several folds until birth, and alpha-Bungarotoxin had no effect on [ 3H]Nicotine binding to fetal brain membranes as well as to adult brain preparations.

TL;DR: The results strongly suggest that L-glutamate is the neurotransmitter in the giant synapse of squid and that JSTX differentiated kainate receptor from glutamate one.

TL;DR: The results indicate that the pontine nuclei and the principal olive provide major afferent inputs to the lateral nucleus, whereas the reticular nuclei, the vestibular nuclea and the accessory olives are the majorAfferent sources to the interpositus nucleus.

TL;DR: The I-type depression in Purkinje cells closely corresponds to the previously reported facilitation in Deiters' neurons and forelimb extensor muscles, suggesting that the interlimb coordination during cat's locomotion is effected by linked activity of vermal Purkin Je cells and Deiter's neurons.

TL;DR: It is concluded that estradiol enhances alpha-bungarotoxin binding capacity in the amygdala by exerting direct effects on the developing amygdala cells.

TL;DR: It was found that the leucine and synthesized membrane proteins moved in the axon, but soluble proteins did not, and this could be explained totally due to intra-axonal diffusion.

TL;DR: Although the growth of neurites from some sympathetic nerve cells of the aged human become independent of the NGF, most of the nerve cells remain dependent on the N GF, even in the stage of senescence.

TL;DR: Results show that the suprageniculate nucleus and the superior colliculus are connected reciprocally and bilaterally, with an ipsilateral dominance.

TL;DR: The results suggest that the INC influences type I neurons through inhibitory action of type II neurons and that it eventually controls the gain, but not the phase, of the horizontal vestibular reflexes.
