Figure 3: The brain of the carrion crow.

(a) Dorsal and (b) lateral view of the crow’s brain. Vertical dashed line indicates section level A5.00 shown in c. The dots in a represent penetration sites of the eight electrodes (2 × 4 grid). (c) Coronal section (A5.00 level indicated by dashed vertical line in a) through the brain of a carrion crow illustrating the borders of the NCL in the caudal telencephalon based on immunohistochemistry for tyrosine hydroxylase. A, Arcopallium; Cb, Cerebellum; Hp, Hippocampal formation; LSt, striatum laterale; NC, Nidopallium caudale; NCL, Nidopallium caudolaterale; Tn, Nucleus taeniae amygdalae; TeO, Tectum opticum. (d) Magnified brain section (coronal plane) from the NCL. Tyrosine hydroxylase-immunoreactive fibres surround perikarya to form ‘baskets’ (arrows). ‘Baskets’ were numerous in the neuropil of the NCL.
