Efferent projections of the parvocellular reticular nucleus to the mesencephalic trigeminal nucleus in rat

Field potentials recorded in the caudal part of the mesencephalic trigeminal nucleus have been studied in response to stimulation of the parvocellular reticular nucleus (PCRt). Besides discharges of spindle afferent units evoked by antidromic stimulation of Probst's tract, relayed and direct af...

Zusammenfassung:	Field potentials recorded in the caudal part of the mesencephalic trigeminal nucleus have been studied in response to stimulation of the parvocellular reticular nucleus (PCRt). Besides discharges of spindle afferent units evoked by antidromic stimulation of Probst's tract, relayed and direct afferent volleys of PCRt fibres were recorded in this nucleus. The results indicate the existence of two populations of PCRt fibres projecting on different regions of the mesencephalic trigeminal nucleus.
