New Values and Hopes

for People with Brain Disorders

Father and Son Playing


We believe that the human brain can change positively regardless of age. We dream of a world where our software makes our brains healthier and happier.

About Us

We take pride in our in-house convergence science, technology and clinical professionals comprised of neuroscientists, neurologists, psychologists, AI scientists, software engineers and clinical trial managers.

It enables us bring neuroscience, medicine and IT together to change how medicine is designed and delivered.


We are building a platform to identify target biomarkers and develop novel digital therapeutics to treat or manage various neuropsychological disorders.


We have initiated a pivotal clinical trial of our first product, Nunap Vision, which provides visual perceptual training to treat visual field defects caused by brain damage. It is the first digital therapeutics clinical trial approved by MFDS in South Korea.


Nunaps stands for Neuron and Synapse, which are key elements that form the basis of our brain. We, Nunapsians, are people who explore the roots of the brain. With constant challenges and passion, we will give new hopes and values to those suffering from diseases.

뉴냅스 이미지-Science 및 Perceptual Learning.JPG


Perceptual learning is defined as experience- or training-dependent performance improvements on a sensory task and is regarded as a manifestation of adult plasticity. In particular, visual perceptual learning (VPL) has attracted attention because of its benefits for visual perceptual ability, and there have been continuous endeavors to use VPL in clinical settings, such as to treat amblyopia, presbyopia, and stroke, and sports settings to enhance sports performance.
