EEG gamma activity to emotional movies

Link – EEG gamma activity to emotional movies in individuals with high traits of primary “successful” psychopathy. Abstract This study aimed to investigate emotional alterations in a community sample with primary psychopathic traits. Sixty males selected from a larger sample and divided in two groups, High (HP) and Low (LP) primary Psychopathy, watched 15 validated […]

Targeting Gamma-Related Pathophysiology

Link – Targeting Gamma-Related Pathophysiology in Autism Spectrum Disorder Using Transcranial Electrical Stimulation: Opportunities and Challenges. Abstract A range of scalp electroencephalogram (EEG) abnormalities correlates with the core symptoms of autism spectrum disorder (ASD). Among these are alterations of brain oscillations in the gamma-frequency EEG band in adults and children with ASD, whose origin has […]

Enhancing gamma oscillations in Parkinsons

Link – Enhancing gamma oscillations restores primary motor cortex plasticity in Parkinson’s disease. Abstract In humans, gamma (γ) oscillations in cortical motor areas reflect asynchronous synaptic activity and contribute to plasticity processes. In Parkinson’s disease (PD), γ oscillatory activity in the basal ganglia-thalamo-cortical network is altered and the long-term potentiation (LTP)-like plasticity elicited by intermittent […]

Modulation of gamma oscillations as a possible therapeutic tool

Link – Modulation of gamma oscillations as a possible therapeutic tool for neuropsychiatric diseases: A review and perspective. Abstract Gamma oscillations (30-80 Hz) are well-known for their role in cortical signal transmission and cognitive brain functions. Aberrant gamma activity has been observed in various neuropsychiatric disorders, but the clinical potential of restoring gamma oscillations via noninvasive […]

Induced Gamma-Band Activity during Actual and Imaginary Movements

Link – Induced Gamma-Band Activity during Actual and Imaginary Movements: EEG Analysis. Abstract The purpose of this paper is to record and analyze induced gamma-band activity (GBA) (30-60 Hz) in cerebral motor areas during imaginary movement and to compare it quantitatively with activity recorded in the same areas during actual movement using a simplified electroencephalogram […]

Closed-loop control of gamma oscillations

Link – Closed-loop control of gamma oscillations in the amygdala demonstrates their role in spatial memory consolidation. Nat Commun. 2019 09 03;10(1):3970 Authors: Kanta V, Pare D, Headley DB Abstract Gamma is a ubiquitous brain rhythm hypothesized to support cognitive, perceptual, and mnemonic functions by coordinating neuronal interactions. While much correlational evidence supports this hypothesis, […]

Lateralised tACS on auditory spatial attention

Link – Opposite effects of lateralised transcranial alpha versus gamma stimulation on auditory spatial attention. Brain Stimul. 2018 Jul – Aug;11(4):752-758 Authors: Wöstmann M, Vosskuhl J, Obleser J, Herrmann CS Abstract BACKGROUND: Spatial attention relatively increases the power of neural 10-Hz alpha oscillations in the hemisphere ipsilateral to attention, and decreases alpha power in the […]

Boosting theta-burst stimulation using gamma tACS

Link – Boosting the LTP-like plasticity effect of intermittent theta-burst stimulation using gamma transcranial alternating current stimulation. Brain Stimul. 2018 Jul – Aug;11(4):734-742 Authors: Guerra A, Suppa A, Bologna M, D’Onofrio V, Bianchini E, Brown P, Di Lazzaro V, Berardelli A Abstract BACKGROUND: Transcranial Alternating Current Stimulation (tACS) consists in delivering electric current to the […]
