tACS on endogenous but not exogenous visual-spatial attention.

Link – Hemisphere-specific, differential effects of lateralized, occipital-parietal α- versus γ-tACS on endogenous but not exogenous visual-spatial attention. Abstract Orienting spatial attention has been associated with interhemispheric asymmetry of power in the α- and γ-band. Specifically, increased α-power has been linked to the inhibition of unattended sensory streams (e.g. the unattended visual field), while increased […]

Effects on motor learning of tACS

Link – Effects on motor learning of transcranial alternating current stimulation applied over the primary motor cortex and cerebellar hemisphere. Abstract Transcranial alternating current stimulation (tACS) is a non-invasive method of brain stimulation that modulates oscillatory neural activity in the cortical area under the electrodes. Gamma (γ)-tACS applied over the primary motor cortex (M1) and […]
