Psychophysical measurement of the effects and non-effects of TMS on contrast perception

Psychophysical measurement of the effects and non-effects of TMS on contrast perception
Transcranial magnetic stimulation (TMS) is widely used to establish causal relationships between brain areas and behavior, but its effects on task performance are not fully understood and have rarely been directly compared between protocols. Decreases in performance on psychophysical tasks, such as those observed when applying TMS, can be attributed to either suppression of stimulus-related neural signals, increased random activity (i.e. neural noise), or a combination of both [1,2]. Indeed, evidence for all three hypotheses has been found when using differing methodologies and online stimulation protocols [3–5]. ... read more
