Transient suppression of primary visual cortex using transcranial magnetic stimulation
نویسندگان
چکیده
Recent advances of transcranial magnetic stimulation can provide new methods to elucidate the mechanism of higher brain function or cortical plasticity. For example, transcranial magnetic stimulation can produce transient disruption of the visual perception or modulation of cortical functions. Probably, the induced eddy current in the brain disturbs the information processing from external signals in the primary visual cortex. Then, if repetitive transcranial magnetic stimulation (rTMS) technique is applied to induce the transient disruption in V1, what would the effect be? In order to verify whether the rTMS is potential to modulate cortical functions, we studied the effect of the visual evoked potentials over the occipital lobe immediately after the rTMS.

Transcranial magnetic stimulation (TMS) has been applied to a growing number of psychiatric disorders as a neurophysiological probe, a primary brain-mapping tool and a candidate treatment. Although most investigations have focused on the treatment of major depression, increasing attention has been paid to anxiety disorders. The aim of this study is to long time (for 30 days) effect of repetitiv...
متن کاملSuppression of premotor cortex disrupts motor coding of peripersonal space
Peripersonal space (PPS) representation depends on the activity of a fronto-parietal network including the premotor cortex (PMc) and the posterior parietal cortex (PPc). PPS representation has a direct effect on the motor system: a stimulus activating the PPS around the hand modulates the excitability of hand representation in the primary motor cortex. However, to date, direct information about...

Voluntary actions typically produce suppression of afferent sensation from the moving body part. We used transcranial magnetic stimulation to delay the output of motor commands from the motor cortex during voluntary movement. We show attenuation of sensation during this delay, in the absence of movement. We conclude that sensory suppression mainly relies on central signals related to the prepar...
