Objective. To explore the correlations between the occurrence and severity of neglect and the region, range or extent of the decrease in regional cerebral blood flow (rCBF).Methods. Nineteen dextromanual patients who were diagnosed as unilateral stroke clinically and hemispa-tial neglect by a neglect test battery received single photon emission computed tomography (SPECT) scans.Results. On images, the damages of patients with neglect were seen most frequently in the frontal cortex, and then in turn in the parietal cortex, occipital cortex, temporal cortex, basal ganglia and thalamus. Most patients with neglect had two or more regions damaged. The most significant region was temporal - parietal - occipital (TPO) junction. The correlation coefficient between rCBF and the severity of neglect was - 0. 34 (t = -1.5, P> 0. 05), and that between the decrease percentage of rCBF and the severity of neglect was 0. 34 (t = 1. 47, P> 0. 05). The correlation coefficients between the range, number of foci, the flow d
