Analysis of Gamma - Band Auditory Responses in Schizophrenia
Title of Document: Analysis of Gamma-Band Auditory Responses in Schizophrenia Benjamin Walsh, Master of Science, 2015 Directed By: Professor Jonathan Simon, Department of Electrical and Computer Engineering, Institute of Systems Research, Department of Biology Schizophrenia is a debilitating mental illness that affects 1% of the general population. One characteristic symptom is auditory halluci...
متن کاملHuman auditory evoked gamma-band magnetic fields.
We have discovered a ca. 40-Hz transient magnetic oscillatory response, evoked in the human brain by the onset of auditory stimuli, consisting of four or more cycles locked in phase to stimulus onset in approximately the 20- to 130-ms poststimulus interval. The response originates in the supratemporal auditory cortex, some millimeters deeper and anterior to the source of the larger-amplitude sl...

متن کاملGamma-band auditory steady-state responses are impaired in first episode psychosis.
BACKGROUND In chronic schizophrenia and chronic bipolar disorder, gamma band (30-100 Hz) auditory steady-state electroencephalogram responses (ASSRs) are reduced in power and phase locking, likely reflecting neural circuit dysfunction. Here we examined whether gamma ASSR deficits are also present at first hospitalization for psychosis. METHODS Subjects were 16 first episode schizophrenia pati...
متن کاملGamma Band Neural Synchronization Deficits for Auditory Steady State Responses in Bipolar Disorder Patients
Periodic auditory click stimulation has been reported to elicit an auditory steady state response (ASSR). The ASSR has been suggested to reflect the efficiency of γ-amino butyric acid (GABA) inhibitory interneuronal activity. Although a potential role for GABAergic dysfunction has been previously proposed, the role of neural synchronization in the ASSR in people with bipolar disorder (BD) has r...
