Cortical auditory EVOKED RESPONSE POTENTIALS (ERPs)
Summary: We measure cortical auditory responses to a novelty oddball paradigm using gel-free, wireless EEG technology customised for 2 year olds, and software which eliminates the need for specialist training in neurophysiology. The oddball paradigm consists of a series of frequent, infrequent and novel auditory stimuli which are presented via wireless earphones to the child. Scalp EEG is recorded from 7 positions (Fz, Cz, Pz, T3, T4, T5 & T6) together with EOG measurements. The numerical values of the amplitudes and latencies of P1, N2 and P3a waves for each of the stimuli are computed together with grand averages. This is automated via a signal processing pipeline QC'd against the Institute of Child Health, London and KEMRI, Kilifi.
Duration: 12 minutes (set up 1 minute, baseline EEG 2 minutes, oddball protocol 8 minutes, conclusion & upload 1 minute)
