Abstract:
Thirteen albino rats with body weight approximately from 0.4～0.6 kg were used in the experiment. Each was injected with 0.1 ?l of 30％ HRP (Sigma Type Ⅵ) solution into one of several portions of the cingulate gyrus. Two days after the injection, the animals were sacrificed and processed with Nauta's DAB and Edward's O-D methods. The results were as follows:1. Area 25 and 32 receive the fibers from areas 3, 1, 2 and globus pallidus on the ipsilateral side, and from areas 10, and 24, caudoputamen nucleus, lateral nucleus of the hypothalamus, intercavernous nucleus of the stria terminalis on both sides. The labeled cells were also found in areas 25 and 32 on contralateral side.2. Area 24 receives fibers from area 32 and the lateral part of the dorsomedial nucleus of the thalamus on the ipsilateral side, and from area 10, the anterior olfactory nucleus, caudoputamen nucleus, and septal nucleus on both sides and from areas 4 and 24 on the contralateral side.3. Areas 23 and 29 receive the fibers from areas 24,17, and 18 on the ipsilateral side, and from areas 23,29,32,25 and rostral part of the linear nucleus on the contralateral side.The results prove that the cingulate area widely receives the afferent fibers from cortex, thalamus, hypothalamus and midbrain.
