Fig. 3

Photographs of brains showing examples of the areas labeled with DiI (outlined arrows) and DiO (black arrows) in various types of experiments. Most applications were done in toto. (a)–(c), and (j) are dorsal views. (d), (h), (k), and (l) are ventral views and (m) is a lateral view. (e) and (f) are dorsal and medial views of the same brain in which the left hemisphere was removed. Examples also include applications to transverse-sectioned en-block brains (g, n, o). In (a–f), (h), and (m), rostral is to the left; in (i–l), rostral is to the top. In (g), (n), and (o), dorsal is to the top. Scale bars: 500 μm (a, i, m); 250 μm (b–h, j–l, n–o)
