Document Summary

Researchers in the 1970s began to study eye movements of monkeys: using single cell recording techniques to study brain areas thought to be associated with eye movements (e. g. superior colliculus, frontal eye fields, parietal cortex, these researchers found neurons that show enhanced activation before and during saccades. One for attentional orienting: reticular activation system (ras, superior colliculus (sc, pulvinar, occipital lobe, parietal lobe, frontal lobe. Human ips and monkey lateral intraparietal sulcus (lip) (cid:224) possibly homologous and may play a role in attentional orienting: studies of single cell recordings (cid:224) lip neurons are enhanced when attention was directed to locations associated with their receptive fields, the attentional processing carried out by this area is not specific to the visual sensory modality, microstimulation of monkey lip neurons also appear to evoke shifts of attention (cid:224) indicated by reduced target detection times in an experiment involving direction location cueing)
