Some Properties of the Thalamic Relay Cells in the Spino‐Cervico‐Lemniscal Path

Some Properties of the Thalamic Relay Cells in the Spino‐Cervico‐Lemniscal Path Cells in nucleus ventralis posterolateralis thalami, lateral to the relay cells of the hindlimb component of the dorsal column pathway, have been studied with extra‐and intracellular recordings in cats anaesthetized with pentobarbital sodium. The cells in this part of thalamus are characterized by a considerable convergence, many cells being excited from the hindlimb component of the spinocervico‐lemniscal (SCLT) and the dorsal column (DC) pathways as well as from forelimb nerves. The synaptic action of an afferent volley was strong, and large unitary EPSPs were frequently observed, particularly when the SCLT was stimulated. Many of the cells were relay cells and could be antidromically invaded from the ipsilateral cortical areas S I and S II. A number of cells were antidromically invaded from both S I and S II, indicating that these cells project to cortex with a divided axon. Many cells showed an inhibition of the recurrent type. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Physiologica Wiley

Abstract

Cells in nucleus ventralis posterolateralis thalami, lateral to the relay cells of the hindlimb component of the dorsal column pathway, have been studied with extra‐and intracellular recordings in cats anaesthetized with pentobarbital sodium. The cells in this part of thalamus are characterized by a considerable convergence, many cells being excited from the hindlimb component of the spinocervico‐lemniscal (SCLT) and the dorsal column (DC) pathways as well as from forelimb nerves. The synaptic action of an afferent volley was strong, and large unitary EPSPs were frequently observed, particularly when the SCLT was stimulated. Many of the cells were relay cells and could be antidromically invaded from the ipsilateral cortical areas S I and S II. A number of cells were antidromically invaded from both S I and S II, indicating that these cells project to cortex with a divided axon. Many cells showed an inhibition of the recurrent type.
