Right hemispheric laterality of human 40 Hz auditory steady-state responses.
Hemispheric asymmetries during auditory sensory processing were examined using whole-head magnetoencephalographic recordings of auditory evoked responses to monaurally and binaurally presented amplitude-modulated sounds. Laterality indices were calculated for the transient onset responses (P1m and N1m), the transient gamma-band response, the sustained field (SF) and the 40 Hz auditory steady-st...
متن کاملImproved Transient Response Estimations in Predicting 40 Hz Auditory Steady-State Response Using Deconvolution Methods
The auditory steady-state response (ASSR) is one of the main approaches in clinic for health screening and frequency-specific hearing assessment. However, its generation mechanism is still of much controversy. In the present study, the linear superposition hypothesis for the generation of ASSRs was investigated by comparing the relationships between the classical 40 Hz ASSR and three synthetic ...
متن کاملGABAergic modulation of the 40 Hz auditory steady-state response in a rat model of schizophrenia.
Auditory steady-state auditory responses (ASSRs), in which the evoked potential entrains to stimulus frequency and phase, are reduced in magnitude in patients with schizophrenia, particularly at 40 Hz. While the neural mechanisms responsible for ASSR generation and its perturbation in schizophrenia are unknown, it has been hypothesized that the GABAA receptor subtype may have an important role....
متن کاملKetamine increases the amplitude of the 40-Hz auditory steady-state response in humans.
The auditory middle latency response (AMLR) and the 40-Hz auditory steady-state response (40-Hz ASSR) are evoked potentials which possibly arise from the same generators in the primary auditory cortex. Both responses are attenuated by most general anaesthetics. Ketamine, however, has been reported to have no effect on the AMLR. Our aim was to evaluate the effects of ketamine on the 40-Hz ASSR. ...
متن کامل40 Hz auditory steady-state response in females: When is it better to entrain?
Auditory steady-state responses (ASSRs) are widely applied to test brain's ability to follow external stimulation in neuropsychiatric disorders. It is known that ASSRs are related to GABAergic transmission. Female sex steroid homones - both estrogens and progesterone - affect functioning of GABAergic system. However, it is not known how these hormones affect brain's ability to entrain. This stu...
