85. Disturbances of Auditory Information Processing in Schizophrenia Reflected by Mmn
in patients who are treatment refractory. We will be examining the association of duration of illness, treatment response and positive and negative symptoms with structural brain abnormalities in 57 schizophrenic patients compared to healthy controls matched for age, SES, gender and handedness. The first patient group has less than 5 years duration of illness (n 5 32) and the second patient gro...
متن کاملHippocampal involvement in detection of deviant auditory and visual stimuli.
Recent models of hippocampal function have emphasized its role in processing sequences of events. In this study, we used an oddball task to investigate hippocampal responses to the detection of deviant "target" stimuli that were embedded in a sequence of repetitive "standard" stimuli. Evidence from intracranial event-related potential studies has suggested a critical role for the hippocampus in...
متن کاملAutomatic Pre-Attentive Auditory Responses: MMN to Tone Burst Frequency Changes in Autistic School-Age Children.
OBJECTIVE Autism is a pervasive developmental disorder that includes deficits in socialization, communication, and adaptive functioning. The mismatch negativity (MMN) is a component of evoked response potentials that reflects pre-attentive change detection. The purpose of this study was to determine whether a group of autistic school-age children had abnormal changes in auditory MMN and to anal...
متن کاملCognitive Neurosciences and Neuropsychology
A deviant sound in a sequence of repeating (standard) sounds elicits the mismatch negativity (MMN) component in the event-related brain potential (ERP) recorded from the scalp.1 The MMN is elicited even when the subject is instructed to ignore the auditory stimuli and attend to other stimuli. In the ERP to deviant sounds, the MMN overlaps with the negative N1 (peak latency about 100 ms from sti...
متن کاملAUDITORY BRAINSTEM RESPONSES (ABR) IN HYPERBILIRUBINEMIC NEWBORNS
To evaluate the changes of ABR values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dL and direct bilirubin less than 2 mg/dL) were selected from those admitted to Children's Medical Center by simple sampling method. These infants had no other problem except jaundice. ABR was taken before treatment in all cases and in some (10 cases) after...
