The effects of bilateral chemical lesions of the ventral striatum (nucleus accumbens and the surrounding areas in the medial striatum) and arcopallium (major descending area of the avian telencephalon) were examined in 1-2-weeks old domestic chicks. Using a Y-maze, we analyzed the lesion effects on the choices that subject chicks made in two tasks with identical economical consequences, i.e., a small-and-close food reward vs. a large-and-distant food reward. In task 1, red, yellow, and green… CONTINUE READING
