Abstract:
We have studied the connections of the nucleus subglomerulosus of the trout posterior tubercle. Main afferents to the nucleus subglomerulosus come from the dorsal telencephalon and the visceral (gustatory) secondary nucleus, while it projects to the optic tectum. In the light of the connections observed, the nucleus subglomerulosus of trout (and probably in other teleosts) appears to be involved in the modulation of sensory-motor tectal processing by olfactory and visceral information.
