| Popis: | Learning and decision-making are greatly influenced by context. When navigating a complex social world, individuals must quickly ascertain where to gain important resources and which group members are useful sources of such information. Such dynamic behavioural processes require neural mechanisms that are flexible across contexts. Here we examine how the social context influences the learning response during a cue discrimination task and the neural activity patterns that underlie acquisition of this novel information. Using the cichlid fish, Astatotilapia burtoni , we show that learning of the task is faster in social groups than in a non-social context. We quantify the neural activity patterns by examining the expression of Fos, an immediate-early gene, across brain regions known to play a role in social behaviour and learning (such as the putative teleost homologues of the mammalian hippocampus, basolateral amygdala and medial amygdala/BNST complex). We find that neural activity patterns differ between social and non-social contexts. Taken together, our results suggest that while the same brain regions may be involved in the learning of a cue association, the activity in each region reflects an individual's social context. |
