Neural entrainment is the phase synchronization of a population of neurons to an external rhythmic stimulus such as applied in the context of transcranial alternating current stimulation (tACS). tACS can cause profound effects on human behavior. However. there remain a significant number of studies that find no behavioral effect when tACS is applied to human subjects. https://www.bekindtopets.com/huge-sale-Jeffers-Citronella-Aloe-All-Natural-Horse-Shampoo-mega-choice/
