Freely moving electrophysiologyWe surgically implant electrodes to gather EEG data from many areas of the brain, such as the prefrontal cortex, hippocampus, amygdala, and dorsal subcoeruleus nucleus. The electrodes remain chronically implanted and enable us record the brain activity of unrestrained & unanesthetized animals. Using this EEG data, we can identify sleep-wake states and perform signal analyses such as an FFT or spectral coherence. This signal processing is used to draw conclusions about the neuronal activity occurring within and between brain regions, giving insight into different brain states.
