— Cerebral protein patterns resolved into 12 soluble fractions by ion exchange and 18 particulate fractions by gel electrophoresis were quantitatively analyzed from the cerebra of naive and trained pigeons. Behavioral treatment affected protein distribution significantly (P < 0.01) in 2 soluble and 2 particulate fractions, and marginally (P < 0.05) in a third fraction. The magnitude of the observed changes ranged from 12 to 57% of control values for a given fraction, but involved very small (< 1 mg/g brain) shifts in absolute protein concentration. These results support the view that protein patterns are basically stable to non‐traumatic behavioral stimulation, but that small changes in specific fractions can occur.
