[Intracranial self-stimulation of the nucleus accumbens of the XXXX and its associated behavior (author's transl)].

@entity935 @entity35 @entity12463 @entity2922
In recent years, the nucleus accumbens (NAS) has gained prominence because of an interest in the role of @entity2922 in the intracranial self-stimulation (ICSS). The NAS receives strong projections from @entity935 of the ventral tegmemtal area (VTA) which form the meso-limbic @entity935 pathway (A10). The major purpose of the present study was to investigate the ICSS of NAS with special emphasis on its associated behavior. The results obtained were as follows: 1. ICSS was observed in @entity35 with electrodes in the NAS. The rate of its ICSS was 230 +/- 142/15 min. 2. @entity12463 ( @entity12463 ) in the VTA were observed with stimulation of NAS including stimulation of sites associated with ICSS. The latency of @entity12463 was 25.5 +/- 4.3 msec. (range 10.0-42.0 msec). 3. ICSS of NAS was chiefly associated with "approach-escape" behavior and/or sniffing for which its electrodes were observed to distribute on widespread scatter through NAS. The electrodes of digging and/or licking groups were localized historogically in the vicinity of the commissura anterior.
