CENTER FOR NEUROSCIENCE IMAGING RESEARCH

Computational Learning & Memory Neuroscience Lab

Introduction 

Research interests of our lab include understanding of cognitive and neural mechanisms underlying motor learning & memory, 

neuromodulaton ofmemory systems and development of efficient learning and rehabilitation protocols. 

We take a combined research approach of computational modeling, psychophysical experiments, neuroimaging, and neuromodulation.

(1) The first specific object is to investigate fundamentals of distinct memory systems related with motor learning, 

not only procedural memory but declarative memory, which cooperatively or competitively interact as the course of acquiring new motor skills.

(2) The second specific objective is to modulate human memory systems using noninvasive stimulation such as transcranial magnetic stimulation (TMS). 

(3) The third specific objective s to develop more efficient learning protocols, potentially applicable to rehabilitation of patients with stroke and

Parkinson’s disease.For this translational research, we are collaborating with clinicians in Bundang Seoul National Hospital and Samsung Medical Center. 

Our laboratory is part of the center for neuroscience imaging research in the Institute of Basic Sciences (IBS) funded by
the Korean government.

Sensorimotor Neuroscience Lab

[Introduction]

"The nervous system and the automatic machine are fundamentally alike in that they are devices, which make decisions on the basis of decisions they made in the past."

- Norbert Wiener  (Mathematician and philosopher, 1894-1964)

SN lab conducts researches on how the neural activities in the human brain are related to psychological processes so-called 'brain functions'. The scientific goal of our lab is to improve the current understanding of fundamental perceptual and cognitive processes through the combination of state-of-the-art technology from pattern recognition, neuroimaging, and rapid prototyping with rigorous psychophysical experiments.
