Brain and Behaviour Physiology Flashcards
1
Q
What do alpha waves on a brain EEG represent?
A
Restful state
2
Q
What do EEGs measure?
A
Voltages generated by excitatory postsynaptic potentials from apical dendrites of massively synchrondrised cortical pyramidal cells
3
Q
How are alpha waves affected when there is excitation of the visual cortex?
A
The wave becomes smaller and more excitable (thicker on appearance)
