Afferents from the reticular complex of the thalamus to the subdivisions of the medial geniculate body (MGB) in the cat were studied by retrograde axonal transport of horseradish peroxidase injected in sites where single unit responses to tones had been characterized.
Abstract
Afferents from the reticular complex of the thalamus (RE) to the subdivisions of the medial geniculate body (MGB) in the cat were studied by retrograde axonal transport of horseradish peroxidase injected in sites where single unit responses to tones had been characterized. All MGB subdivisions studied received afferents from the same region of RE corresponding to its ventral posterior third, characterized by large neurons. No obvious differences were seen in the localization of labelled neurons within RE according to which MGB subdivision was injected, except that pars lateralis afferents seemed to originate from somewhat more limited portions of RE.

This finding suggests that GABA-mediated inhibition of GABA neurons may occur in the NR of normal (untreated) rats, and the large number of GAD-positive cell bodies within the NR contrasts with a paucity of positively-stained somata in the more internally located thalamic nuclei.

Because of the wide extent of the dendritic fields of the reticular cells and the degree of overlap between the sectors of the complex subtended by adjacent dorsal thalamic nuclei and adjacent cortical areas, it is likely that thereticular complex samples thalamo‐cortical and cortico‐thalamic activity in a somewhat unspecific manner.

The descending projections of nucleus cuneiformis in the cat were traced by autoradiography in the transverse and sagittal planes following stereotaxically placed injections of 3H‐leucine to discuss the role of the midbrain reticular formation in the elaboration of certain forms of behavior.

The sources of ascending input to the medial geniculate body of the cat were studied using the retrograde transport of horseradish peroxidase to provide evidence for multiple parallel auditory pathways through the thalamus.

It is found that definite boundaries can be determined at which there is a distinct change in response properties; the position of these “physiological boundaries” seems to correspond with the boundaries between the seven subnuclei of the MGB described by Morest.

The author's express wish is to make accessible to the non-specialist the recent work and ideas concerned with the subcellular organization of the neuron, and especially the synapse, and within this scope the material is very well organized.

It is suggested that A-TR neurons are intercalated in the axon collateral circuit of the thalamocortical projection arising from relay neurons of the MG.

It was found that single-shock stimulation of a group of interneurons elicited IPSPs that were effective to make principal cells unresponsive to optic tract stimuli and to arrest the cells' spontaneous discharges.

It is revealed that the inferior colliculus is an obligatory relay for the overwhelming majority of axons comprising the lateral lemniscus and originating in the cochlear nucleus and superior olive.

Over 2500 extracellular single unit recordings were obtained from the medial geniculate body (MGB) of cats anaesthetized with nitrous oxide, finding phase-locked neurons, principally found in the pars lateralls, but also in the Pars magnocellularis and pars ovoidea of the MGB.

In urethane‐anaesthetized rats, studies were made on unit discharges of neurones of the thalamic reticular nucleus (tr) receiving the somatosensory input and it is suggested that most, if not all, of the s‐tr neurones are innervated by axon collaterals of the vb relay cells.

There is a small population of “lockers” which show a non-monotonic response to increasing click frequency, which might be involved in the temporal coding of natural sounds such as animal vocalizations and the cat's purr.

The aim of this study was the analysis of coding properties of the different nuclei of the MGB to simple acoustic stimuli, with emphasis on response latencies, temporal response patterns, frequency tuning and binaural properties.
