Research project investigating the role of acetylcholine in attention mechanisms in macaque visual cortex using advanced recording techniques.
Description
This study tests three competing models for the role of the neuromodulator acetylcholine (ACh) in attention by employing electrochemistry and electrophysiology in the visual cortex of macaque monkeys performing a cued orientation-change-detection task. The project aims to measure the concentration, timing, and spatial extent of ACh release during an attention task in a primate.
