c-fos Changes following an aggressive encounter in female California mice: a synthesis of behavior, hormone changes and neural activity.

摘要: Although there has been growing interest in the neuroanatomical and physiological mechanisms underlying aggressive behavior, little work focused on possible controlling natural plasticity aggression. In current study, we used naturally occurring changes aggression level displayed by female Peromyscus californicus across estrous cycle parallel c-fos expression to examine brain regions involved mediating this plasticity. We found that was increased females exposed a conspecific intruder compared with control numerous thought be of More importantly, bed nucleus stria terminalis (BNST) ventral lateral septum (LSv) only more aggressive, diestrous females, not less proestrous females. Conversely, medial amygdala (MeA) all stages estrus controls, suggesting MeA is individual levels Moreover, correlations between several measures BNST LSv but MeA, again role for former two latter region. further hypothesize may generally aggression, such as increases often observed after individuals win interactions against conspecifics.
