title: Effects of nerve growth factor on behavioral recovery following caudate nucleus lesions in rats.
abstract: Rats with bilateral lesions of the caudate nucleus received intracaudate injections of either nerve growth factor protein (NGF) on inert buffer immediately following surgery. NGF-treated animals demonstrated a faster recovery of normal appetitive behavior and perseverated less than their buffer-treated counterparts on a spatial reversal task, but both groups were impaired relative to sham controls on acquisition of an active avoidance response. Glia to neuron ratios were significantly increased in both lesion groups when compared with sham controls. However, this increase was less in the NGF-treated animals than in the buffer-treated animals. NGF treatment had no effect on steady-state caudate dopamine levels, measured six months after surgery.
