Romanska. High frequency transcranial random noise stimulation enhances perception of facial identity. Cerebral Cortex, pp. 4334-4340, 2015.

Abstract: Recently, a number of studies have demonstrated the utility of transcranial current stimulation as a tool to facilitate a variety of
cognitive and perceptual abilities. Few studies, though, have examined the utility of this approach for the processing of social
information. Here, we conducted 2 experiments to explore whether a single session of high-frequency transcranial random
noise stimulation (tRNS) targeted at lateral occipitotemporal cortices would enhance facial identity perception. In Experiment 1,
participants received 20 min of active high-frequency tRNS or sham stimulation prior to completing the tasks examining facial
identity perception or trustworthiness perception. Active high-frequency tRNS facilitated facial identity perception, but not
trustworthiness perception. Experiment 2 assessed the spatial specificity of this effect by delivering 20 min of active highfrequency
tRNS to lateral occipitotemporal cortices or sensorimotor cortices prior to participants completing the same facial
identity perception task used in Experiment 1. High-frequency tRNS targeted at lateral occipitotemporal cortices enhanced
performance relative to motor cortex stimulation. These findings show that high-frequency tRNS to lateral occipitotemporal
cortices produces task-specific and site-specific enhancements in face perception.

Keywords: brain stimulation, face perception, facial identity, transcranial current stimulation, transcranial random noise stimulation
