Transcranial alternating current stimulation affects motion adaptation in V1 and MT neurons in awake, behaving macaques

چکیده
Transcranial electrical stimulation (tES) has been widely used in the clinic and in behavioral neuroscience research. The effects of transcranial alternating current stimulation (tACS) range from treating depression to augmenting human cognition. Optimization of tACS protocols will require an understanding of the mechanisms of actions of externally applied electric fields on the brain. We have started to probe the influence of tACS on the well-explored macaque visual system, specifically area V1 and MT. We have observed that tACS reduces motion aftereffect in human subjects (Kar et al. 2012, VSS abstract). This leads to the hypothesis that subthreshold rhythmic membrane voltage modulations produced by tACS reduces adaptation in the motion selective neurons.

Transcranial electrical stimulation affects adaptation of MT/V5 neurons in awake, behaving macaques
Despite widespread use in clinical and behavioral studies, the mechanisms of action of transcranial electrical stimulation (tES) are poorly understood. We partially attribute this to the lack of in-vivo animal models and have started to probe the influence of tES on the wellexplored macaque visual system, specifically area MT. Previously we have shown that tES reduces the motion aftereffect in ...
متن کاملTranscranial Alternating Current Stimulation Attenuates Neuronal Adaptation.
We previously showed that brief application of 2 mA (peak-to-peak) transcranial currents alternating at 10 Hz significantly reduces motion adaptation in humans. This is but one of many behavioral studies showing that weak currents applied to the scalp modulate neural processing. Transcranial stimulation has been shown to improve perception, learning, and a range of clinical symptoms. Few studie...
متن کاملMotion-Sensitive Neurones in V5/MT Modulate Perceived Spatial Position
Until recently, it was widely believed that object position and object motion were represented independently in the visual cortex. However, several studies have shown that adaptation to motion produces substantial shifts in the perceived position of subsequently viewed stationary objects. Two stages of motion adaptation have been proposed: an initial stage at the level of V1 and a secondary sta...
متن کاملEffect of Transcranial Alternating Current Stimulation on Anxiety and Hemodynamic Response in Patients Undergoing Surgery: A Double-Blind Controlled Clinical Trial
Background: Pre-op anxiety has adverse effects on the patientchr('39')s anesthesia and treatment. Currently, electrical interventions are widely used as non-invasive methods to control pre-op anxiety and may have advantages as compared with medical therapies. This study aimed to determine the effect of transcranial alternating current stimulation on anxiety and hemodynamic response of patients ...
متن کاملNatural stimulation of the nonclassical receptive field increases information transmission efficiency in V1.
We have investigated how the nonclassical receptive field (nCRF) affects information transmission by V1 neurons during simulated natural vision in awake, behaving macaques. Stimuli were centered over the classical receptive field (CRF) and stimulus size was varied from one to four times the diameter of the CRF. Stimulus movies reproduced the spatial and temporal stimulus dynamics of natural vis...
