a, Diagram of the amygdala complex with the position of the photomicrograph (shown in b) demarcated by the enclosed box and the area of the lesion identified by broken lines. b, Heavy gliosis marks the site of the lesion in the CN surrounding the stria terminalis. c, Autoradiogram shows DA uptake sites labeled with [³H]Mazindol. High levels of binding (dark area) are evident throughout the intact striatum on the right. The site of 6-OHDA administration on theleft exhibits low binding, indicative of a loss of DA innervation. Average lesion area was 3.03 mm², and radioactive density averaged 1.88 nCi/mg relative to 8.35 nCi/mg on the contralateral side. ABL, Basolateral nucleus;CN, central nucleus; ME, medial nucleus;st, stria terminalis.
