we examined the distribution of neuropeptide y immunoreactive local circuit neurons and nonphosphorylated neurofilament ( smi 32 ) immunoreactive pyramidal projection neurons in superior frontal cortex of patients with huntington 's disease and age-matched control subjects to determine the histological counterpart of increased neuropeptide y and decrease glutamate concentrations previously found in the cortex of patients with huntington 's disease .
