Somatostatin-like immunoreactivity characterizes neurons of the nucleus reticularis thalami in the cat and monkey.
This report presents immunohistochemical evidence for the occurrence of a somatostatin-related peptide in neurons of the thalamic reticular nucleus, a nucleus known to modulate thalamic activity by y-aminobutyric acid (GABA)-mediated inhibition. In eight cats and kittens and one rhesus monkey, sections through the nucleus reticularis thalami and adjoining regions of the thalamus, subthalamus, a...
متن کاملExpression of a functional hyperpolarization-activated current (Ih) in the mouse nucleus reticularis thalami.
The GABAergic neurons of the nucleus reticularis thalami (nRT) express the type 2 hyperpolarization-activated cAMP-sensitive (HCN2) subunit mRNA, but surprisingly, they were reported to lack the hyperpolarization-activated (Ih) current carried by this subunit. Using the voltage-clamp recordings in the thalamocortical slice preparation of the newborn and juvenile mice (P6-P23), we demonstrate th...
متن کاملA model of the electrophysiological properties of nucleus reticularis thalami neurons.
A model of the electrophysiological properties of rodent nucleus reticularis thalami (NRT) neurons of the dorsal lateral thalamus was developed using Hodgkin-Huxley style equations. The model incorporated voltage-dependent rate constants and kinetics obtained from recent voltage-clamp experiments in vitro. The intrinsic electroresponsivity of the model cell was found to be similar to several em...
متن کاملMechanisms of oscillatory activity in guinea-pig nucleus reticularis thalami in vitro: a mammalian pacemaker.
1. The ionic mechanisms of rhythmic burst firing and single spike, tonic discharge were investigated with extracellular and intracellular recordings of single neurones in the guinea-pig nucleus reticularis thalami (NRT) maintained as a slice in vitro. 2. Activation of cortical/thalamic afferents to NRT neurones resulted in a short latency burst of action potentials which could be followed by a ...
متن کاملNucleus limitans thalami--comparative anatomical study.
Cyto- and myeloarchitectonics as well as acetylcholinesterase activity of the nucleus limitans thalami--an important part of the nociceptive system--were studied in insectivora (Sorex araneus, Erinaceus europaeus, Talpa europaeus), rat, rabbit, cat, monkey and man. Our results suggest that nucleus limitans is phylogenetically a rather new structure. In insectivora and in the rat we could not fi...
