Summary
-
1.
A study of activity of mesencephalic reticular neurons has shown that different influences can converge on them. However, 20% of reticular neurons responded to none of the stimuli used. Nonresponding reticular neurons were characterized either by a high firing rate or by the exceptionally regular character of their activity.
-
2.
Mesencephalic reticular neurons responding to stimuli were chiefly excited by corticofugal impulses from the first sensorimotor area and inhibited by influences from the lateral parts of the posterior hypothalamus.
-
3.
In combined cortico-thalamic influences on the activity of mesencephalic reticular neurons, the dominant role is played by the hypothalamus.
