Summary of auditory effects in non-auditory cortices

Area Suprathreshold effect Subthreshold effect
AEV 19% Facilitory 11% Facilitory
RSS 21% Facilitory 11% Suppressive
PLLS 9% Facilitory 16% Facilitory
Area 21 0% 0% GABA mediated
Facilitation

In the non-auditory areas sampled (AEV, RSS, PLLS and Area 21), this table lists the proportion (%) of neurons encountered that exhibited suprathreshold (e.g., were bimodal) or subthreshold multisensory properties. When non-auditory versus combined responses were plotted for each neuron type, the general slope of the activity of the population fell either above (facilitory) or below (suppressive) the line of unity. Note that Area 21 neurons showed subthreshold multisensory facilitation only when local GABAergic circuits were pharmacologically blocked.
