title: Biochemical differences between the left and right hemispheres. Preliminary observations on choline acetyl transferase (CAT) activity.
abstract: Choline acetyltransferase (CHAT) activity was studied in different areas in the first temporal gyrus of left and right hemispheres of human brains. The CHAT activity values obtained in all the samples from left hemisphere wee significantly higher than in the right hemisphere. The biochemical data seems to suggest a possible morphological and/or functional differences between the two hemispheres.
