Asymmetry in the chicken forebrain during development and a possible involvement of the supraoptic decussation.
During the first week of post-hatch life, the chicken forebrain is asymmetrically susceptible to the action of cycloheximide. Between days 2 to 8 treatment of the left hemisphere, but not the right, causes long-lasting changes in behaviour. The right hemisphere is susceptible on days 10 and 11. These developmental events may be related to a significant loss of fibres in the supraoptic decussation, which occurs around the same time.
