Document Summary

Superior colliculus: saccades and attention shifting is controlled here. Thalamas: many areas of thalamas, but specifically the pulvinar is of interest to us in this class: pulvinar is active when we are trying to focus on one thing and there is a lot of noise around us. Frontal cortex: includes acc, executive control area (voluntarily moving attention around) Aside from frontal cortex, function of brains in humans + monkeys are similar. We have learned a lot about the parietal, temporal, and visual cortex. Lots of research used direct cueing tasks to train monkeys. Chemical basis of attention: different types of neurotransmitters (look at 3 main ones) Serotonin: there is 70%ish percent of this found in gut, related to mood. Ne: this increases as we are more alert. Ne and serotonin have reciprocal relationship, as ne , se .
