Area 13 Of Prefrontal Cortex

METHODS AND RESULTS: To address this problem, the effects of chronic ethanol self-administration in male cynomolgus monkeys on GABA(A) receptor subunit mRNA expression was studied in 3 frontal cortical fields: orbitofrontal cortex (OFC; area 13), anterior cingulate cortex (ACC; area 24), and the dorsolateral prefrontal cortex (DLPFC; area 46).  

When this small increase is combined with their earlier findings on area 13 of prefrontal cortex (Semendeferi et al.  

The results indicated that the caudal orbitofrontal cortex, area 13, which is powerfully linked to the medial temporal limbic region and is involved in the regulation of autonomic responses, is a key part of the frontal cortex responding in the face of unpleasant incoming information..  

The dorsal midline nuclei project densley to area 13, agranular insular cortex (Ia), and Acb.  

Labeled neurons in primary olfactory areas (prepiriform cortex, anterior olfactory nucleus and olfactory tubercle) were directed mainly to a posterior orbitofrontal region and to a lesser extent the neighboring caudal part of area 13. There was no evidence of direct projections from primary olfactory areas to the rostral parts of area 13, or to areas 12 or 11.  

Using the above architectonic criteria, we observed that one of the architectonic trends takes a radial basoventral course from the periallocortex in the caudal orbitofrontal region to the adjacent proisocortex and then to area 13.
