[Neuronal reactions of the reticular nucleus and adjacent thalamus structures in the cat to natural stimulation in a chronic experiment].

Spike responses of 104 neurons of the nucleus reticularis thalami (R) and neighbouring thalamic nuclei to the acoustic stimuli, tactile and visual stimulation were studied in the chronic experiment. 29% of neurons responded to the acoustic stimulation and 11% of them were not specific to different acoustic stimuli. The minimal latency of the excitation to the acoustic stimulation was 12-37 ms and that of the inhibition--18-27 ms. The duration of the excitation in response to the acoustic stimulation was 50-250 ms and that of inhibition--27-190 ms. 16% of R neurons responded to the stimulation of different sensory systems. The majority of R neurons showed excitation in response to different stimuli and only 4-10% of neurons showed inhibition.
