We compared the connections of two areas within rat cingulate cortex, the Cg1/Cg2 area vs the Cg3 area, by iontophoresing small quantities of wheatgerm agglutinin-horseradish peroxidase (WGA-HRP) into either of these two divisions and identifying…
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…
