GABA metabolism and its role in gamma‐band oscillatory activity during auditory processing: An MRS and EEG study
Sign Up to like & getrecommendations! Published in 2017 at "Human Brain Mapping"
DOI: 10.1002/hbm.23642
Abstract: Gamma‐aminobutyric acid (GABA) and glutamate are believed to have inhibitory and exhibitory neuromodulatory effects that regulate the brain's response to sensory perception. Furthermore, frequency‐specific synchronization of neuronal excitability within the gamma band (30–80 Hz) is… read more here.

DOI: 10.1002/hbm.25831
Abstract: Conceptual alignment is a prerequisite for mutual understanding. However, little is known about the neurophysiological brain‐to‐brain underpinning during conceptual alignment for mutual understanding. Here, we recorded multi‐channel electroencephalogram (EEG) simultaneously from two participants in Experiment… read more here.

DOI: 10.1007/s12264-018-0208-8
Abstract: Gamma band oscillation (GBO) and sensory gating (SG) are associated with many cognitive functions. Ketamine induces deficits of GBO and SG in the prefrontal cortex (PFC). However, the time-courses of the effects of different doses… read more here.

DOI: 10.1016/j.clinph.2018.08.007
Abstract: OBJECTIVES The gamma-band auditory steady-state response (ASSR) is thought to reflect the function of parvalbumin-positive γ-aminobutyric acid (GABA)-ergic interneurons and may be a candidate biomarker in early psychosis. Although previous cross-sectional studies have shown that… read more here.

DOI: 10.1016/j.jad.2018.05.078
Abstract: BACKGROUND The functional networks are associated with emotional processing in depression. The mapping of dynamic spatio-temporal brain networks is used to explore individual performance during early negative emotional processing. However, the dysfunctions of functional networks… read more here.

DOI: 10.1016/j.nbd.2018.01.010
Abstract: Maintained gamma band activity is a key element of higher brain function, participating in perception, executive function, and memory. The pedunculopontine nucleus (PPN), as part of the reticular activating system (RAS), is a major source… read more here.

DOI: 10.1016/j.neuroimage.2018.09.047
Abstract: &NA; Low frequency oscillations such as alpha (8–12 Hz) are hypothesized to rhythmically gate sensory processing, reflected by 40–100 Hz gamma band activity, via the mechanism of pulsed inhibition. We applied transcranial alternating current stimulation… read more here.

DOI: 10.1016/j.neuroimage.2022.119077
Abstract: Phonological difficulties characterise individuals with dyslexia across languages. Currently debated is whether these difficulties arise from atypical neural sampling of (or entrainment to) auditory information in speech at slow rates ( read more here.

DOI: 10.1016/j.pnpbp.2018.04.016
Abstract: &NA; Abnormal auditory steady state response (ASSR) is a typical finding among schizophrenia patients, which is thought to directly reflect deficient gamma band oscillations in the brain. However, whether these ASSR alterations are state dependent,… read more here.
