Left-right asymmetry in vertebrate nervous systems. A, Asymmetric protein distribution in the dorsal habenular nuclei (hab) and their efferent projections to the midbrain IPN in a larval zebrafish revealed by immunofluorescence (Gamse et al., 2005). B, Left habenular axons (red) project along the entire dorsoventral extent of the IPN, whereas right habenular axons (green) project only ventrally. Shown are transverse sections of an adult brain immunolabeled for two proteins that are expressed to a greater extent in left (as in A) or right habenular neurons and their axons (image courtesy of Y.-S. Kuan). C, Head position of a day 18 chick embryo within the egg results in lateralized light input and asymmetry in the developing visual system (Rogers, 1990). Only the right eye is exposed to light in both chick and pigeon (data not shown) embryos. D, Adult pigeon with cap over the right eye infront of two pecking keys showing patterns. To the bottom are some of the other 725 abstract patterns that the animals had to memorize. The left hemisphere (right eye) was superior in memorizing visual patterns (from von Fersen and Güntürkün, 1990). E, MRI images depicting L-R asymmetry in the motor-hand area of the precentral gyrus of different primates. All brains are shown to scale and oriented as for the human.
