Abnormal neural synchrony in schizophrenia.
Schizophrenia has been conceptualized as a failure of cognitive integration, and abnormalities in neural circuitry (particularly inhibitory interneurons) have been proposed as a basis for this disorder. We used measures of phase locking and phase coherence in the scalp-recorded electroencephalogram to examine the synchronization of neural circuits in schizophrenia. Compared with matched control...
متن کاملNeural synchrony indexes disordered perception and cognition in schizophrenia.
Current views of schizophrenia suggest that it results from abnormalities in neural circuitry, but empirical evidence in the millisecond range of neural activity has been difficult to obtain. In pursuit of relevant evidence, we previously demonstrated that schizophrenia is associated with abnormal patterns of stimulus-evoked phaselocking of the electroencephalogram in the gamma band (30-100 Hz)...
متن کاملNeural synchrony in schizophrenia: from networks to new treatments.
Evidence is accumulating that brain regions communicate with each other in the temporal domain, relying on coincidence of neural activity to detect phasic relationships among neurons and neural assemblies. This coordination between neural populations has been described as "self-organizing," an "emergent property" of neural networks arising from the temporal synchrony between synaptic transmissi...
متن کاملDeficient motor synchrony in schizophrenia.
A laboratory measure of motor function, synchronization of tapping with an auditory stimulus, was introduced as an index of motor disorganization in schizophrenia. It was hypothesized that (a) schizophrenics' performance on this task would be distinguishable from that of controls and would reflect a relative inability to take advantage of stimulus predictability, independent of task difficulty;...
متن کاملNeural Synchrony and Neural Plasticity in Tinnitus
1. Most individuals with chronic tinnitus have highfrequency hearing loss, induced by noise exposure, otological disease, or the aging process. Physiological evidence suggests that in such individuals, tinnitus is likely caused not by irritative processes that persist in the ear after cochlear injury, but by changes that occur in central auditory pathways when the ear is partly disconnected fro...
