... unclear whether they are responsive to external stimuli and thereby capable of contributing to behavioural change. We tested whether cells born in the telencephalon of adult zebrafish are activated by social stimuli. We marked cell birth with BrdU and, 40 d later, exposed fish to brief (15 min) visual...
