p232fig05.40 Computer simulation of how the SMART mode generates (a) gamma oscillations if a good enough match occurs, or (c) beta oscillations if a bad enough match occurs.  See the text for details.<BR>||  Brain oscillations during match/mismatch, data, simulation. (a) TD corticothalamic feedback increases synchrony (Sillito etal 1994) (b) Match increases γ oscillations (c) Mismatch increases θ,β oscillations
