By using fluorescent retrograde tracers, we compared efferent projections of the medial frontal cortex to two subcortical areas: the superior colliculus, a somatic motor area, and the laterodorsal tegmental nucleus, a visceral motor area. Neurons…
A large injection of a retrograde tracer into the inferior colliculus of guinea pigs labeled two bands of cells in the ipsilateral auditory cortex: a dense band of cells in layer V and a second band of cells in layer VI. On the contralateral side,…
Naloxone eliminates postexertional hypotension (PEH) in human and animal models. The effect of naloxone on sympathetic activity during hemorrhage and generation of arterial baroreflex function curves can be stimulated by blockade of cardiac afferent…
