Computing half-area latency in matlab/EEGLAB
Tweet Share Email Share Share FollowIn EEG research the latency of a component (hidden in the ERP) is conventionally measured as the time when the ERP is most extreme. However, this method is not well warranted, as should be clear to anyone who have read Steven Lucks excellent chapters on ERP analysis in “An Introduction to the Event Related Potential Technique”. Instead he proposes a 50% area latency method: the latency is the point in time where the area under the curve is equal on both sides. It yields the same latencies as peak-measures on symmetrical ERPs and more correct latencies …
