Spatial inhibition and the visual cortex: A magnetic resonance spectroscopy imaging study

▸ Methamphetamine (MA) abusers and controls did not differ on a spatial attention test. ▸ Group differences in neurometabolites were not seen in Primary Visual Cortex (PVC). ▸ PVC neurometabolites correlated with spatial attention performance. ▸ Results suggest that PVC may modulate spatial attention in MA abusers.
