Improvement in visual perception after high-frequency transcranial random noise stimulation (hf-tRNS) in those with migraine: An equivalent noise approach

Migraine is a common neurological disorder with strong links to vision. Interictal migraine thought be characterised by internal noise in the brain, possibly due increased variability neural firing, which can estimated using equivalent tasks. High-frequency transcranial random stimulation (hf-tRNS) used modulate levels of and so presents possible therapy redress brain. This case-control study 2-alternative forced choice (2AFC) design. Hf-tRNS Sham control were alongside global motion direction discrimination task visually based The group demonstrated baseline compared group. Internal levels, sampling, reduced hf-tRNS but not stimulation. However, there no differences terms coherence thresholds, slopes, lapse rate for between two groups. first demonstration possibility decreasing hf-tRNS. Future work could explore neurostimulation as migraine.
