Nucleo mesencefalico del trigemino nell'anitra: effetti della stimolazione del nervo vago e della sostanza reticolare
The masseteric reflex elicited by electrical stimulation of the mesencephalic trigeminal nucleus (MTN) was influenced by electrical stimulation of the central stump of the vagal nerve and of the reticular formation in the duck; the vagal nerve exerted predominantly inhibition while the reticular formation could inhibit or enhance the jaw reflex movements: increase was the most common effect. Unitary discharge of the MTN was recorded in curarized ducks by means of tungsten microelectrodes. Units...
