A) Effects of 9d auditory exposure on neural responses. Top: Absolute Response Magnitudes (ARMs) for trials 2–6 in the left (solid bar) and right (striped bar) hemispheres for birds that spent 9d in either CONENV (black) or HETENV (red). CONENV birds had higher ARMs in the right hemisphere while HETENV birds showed higher ARMs in the left hemisphere, yielding a significant environment by hemisphere interaction (F(1,369)=8.5064, P<0.0038). Bottom: Adaptation Rates for trials 6–25. CONENV birds had faster adaptation in the right hemisphere while HETENV birds did not have a hemispheric difference in adaptation rates, once again showing a significant environment by hemisphere interaction (F(1,369)=5.5079, P<0.0195). B) Effects of 4d auditory exposure on neural responses. Top: ARMs trials 2–6 in the left and right hemispheres for birds that spent 4d in either CONENV or HETENV. CONENV birds had slightly higher ARMs in the right hemisphere while HETENV birds had higher ARMs in the left hemisphere, yielding a significant environment by hemisphere interaction (F(1,258)=8.2314, P<0.0045). Bottom: Adaptation Rates for trials 6–25. CONENV birds had faster adaptation rates in the right hemisphere while HETENV birds had faster adaptation rates in the left hemisphere, leading to a significant environment by hemisphere interaction (F(1, 258)=8.0441, P<0.0049). Error bars represent standard error of the mean (SEM). Asterisks denote significant main effects and interactions.
