    Pontomedullary reticular formation neurones : a study of microanatomy, transmitter sensitivity and connections from the substantia nigra pars reticulata
    (1990) Kellaway, Lauriston Arthur; Douglas, Rodney J
    This investigation examines certain aspects of the medial pontomedullary reticular formation (PMRF) microanatom y and neurotransmission and also the connections between the substantia nigra pars reticulata (SNr) and the PMRF in the rat. The anatomical distribution of the population of PMRF neurones was determined by combining physiological identification with electrical stimulation and retrograde HRP tract-tracing. A dual stimulating/deposition electrode was used to combine antidromic stimulation of PMRF cells with optimal retrograde labelling. 139 PMRF neurones were identified by means of their stereotaxic location and physiological criteria, namely; spontaneous discharge, polymodal sensory responses and large receptive fields.
