Duration-MMN
Auditory Mismatch Negativity (MMN) is an event related potential that is elicited by irregularities in a constant auditory stream, e.g. during an oddball paradigm, where repetitive standard sounds are interspersed with infrequent deviants.
Reductions in MMN-responses are well established in schizophrenia. However, evidence for MMN impairments in Clinically High Risk for Psychosis (CHR-P) and First Episode Psychosis (FEP) patients groups is less well-established.
In this project, we examined magnetoencephalographically (MEG) recorded responses to duration deviants to establish whether MMN responses are impaired during early stage psychosis.
Here is my poster summarising this work
