EEG Basics: How Brain Activity Becomes a Signal
Article summary
Quick briefing — cleaned from the original RSS feed
Adapted from an appendix of my MS thesis. Basic Principles The origin of electroencephalogram (EEG) signals comes from neurons creating electrical signals that are transmitted to other cells through synapses. An action potential (AP) arrives at a synaptic cleft (step 1 in the figure) where it transmits chemical information through neurotransmitters (step 2) that generate postsynaptic potentials (PSPs) and local current (step 3). A PSP will create a current sink and will propogate to the cell…
