The effect of transcutaneous auricular vagal nerve stimulation on pupillary response and perceptual learning.

Brief description of study

Study 1: We will observe the use of taVNS versus sham setting(s) on healthy human subjects and observe pupillary response in a passive study session. All subjects will receive taVNS and two sham settings (lobe stimulation and ulnar wrist stimulation) and no stimulation at all. Study 2: We will evaluate behavior on a perceptual learning in a go/no-go task paradigm where healthy human subjects will receive either taVNS, sham, or no intervention. We will also record pupil dilation on task performance to index overall effort and cognitive demand.
