Enhancing human perception through learning, neuromodulation, and brain-computer interfaces Fang Fang

A core ultimate objective of human perception research is to boost human perceptual performance, which might be achieved through perceptual learning and neuromodulation. I first describe the behavioral characteristics and neural mechanisms of perceptual learning revealed by psychophysics, multimodal neuroimaging, and intracranial neural recording, and how social context, non-invasive neuromodulation, and repetitive sensory stimulation affect the acquisition and consolidation of perceptual learning. Then I demonstrate that, contrary to the long-standing view that perceptual learning demands extensive training, brief reactivation of perceptual experience during wakefulness and sleep is sufficient to elicit robust perceptual learning. Finally, I will show that transcranial electrical stimulations and brain-computer interfaces (BCIs) can enhance and even restore human perceptual capabilities.
