Fig. 371. Principal afferent and efferent suprasegmental pathways

(excepting the archipallial connections, the efferent connections of the mid- brain roof and the olivo-cerebellar connections)

Neopallial connections are indicated by broken lines. Intersegmental connections are omitted Some peripheral elements are indicated. Each neurone group (nucleus and fasciculus) is in dicated by one or several individual neurones. Decussations of tracts are indicated by an X

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?
