Morphological and functional types of neurons in cat ventral posterior thalamic nucleus.
Neurons in the thalamic ventral posterior (VB) nucleus of the cat were investigated by extracellular and intracellular recording and by anatomical methods involving either the retrograde transport of horseradish peroxidase (HRP) or the intracellular injection of HRP. Two morphological types of neurons could be detected by retrograde labeling from small injections of HRP in the internal capsule ...
متن کاملFunctional characteristics of the parallel SI- and SII-projecting neurons of the thalamic ventral posterior nucleus in the marmoset.
The functional organization of the primate somatosensory system at thalamocortical levels has been a matter of controversy, in particular, over the extent to which the primary and secondary somatosensory cortical areas, SI and SII, are organized in parallel or serial neural networks for the processing of tactile information. This issue was investigated for the marmoset monkey by recording from ...
متن کاملModulation of the spontaneous and evoked discharges of ventral posterior thalamic neurons during shifts in arousal.
The responses of 154 ventral posterior thalamic neurons to a variety of somatic stimuli and to electrical stimulation of the midbrain spinal lemniscus were recorded in the awake squirrel monkey during varying states of arousal. Many VP (42/93) neurons showed changes in somatosensory responsiveness which correlated with shifts in arousal. Arousal related modulation (ARM) of somatic responses wer...
متن کاملGABA(B)-receptor-mediated inhibition in developing mouse ventral posterior thalamic nucleus.
Inhibitory postsynaptic potentials (IPSPs) generated by activation of the thalamic reticular nucleus (RTN) were recorded in neurons of the ventral posterior nucleus (VP) in vitro in slices from mice aged postnatal day (P)1-P17. An early IPSP peaking 41 +/- 2.5 (SE) ms after electrical stimulation of the internal capsule or RTN was found in 96% of VP neurons. This early IPSP was blocked by bicuc...
