title: Delayed c-fos expression in sensory cortex following sexual learning in male rats.
abstract: An elevated expression of c-fos protooncogene, encoding transcription factor Fos, is known to serve as a useful marker of neuronal activation. In the studies reported in this communication we have used Northern and dot blot techniques to analyze c-fos mRNA levels in male rat brain during the learning of the copulatory behavior. The animals were trained (single ejaculation in a training/testing session) for up to 7 sessions. C-fos mRNA levels have been found to increase in the sensory cortex area following the third and fifth session but not after the first and the last one.
