Does the ascending cholinergic projection inhibit or excite neurons in the rat thalamic reticular nucleus?

In rats anesthetized with urethan, neuronal activity was recorded in those portions of the thalamic reticular nucleus (TR) excitable by visual, somatosensory, or auditory input. Observations were made on changes in rate and pattern of discharge of these neurons during repetitive stimulation of the laterodorsal tegmental nucleus (LDT), which is composed of… CONTINUE READING
