Neuroimaging for tactile perception

OVERVIEW

- Aim

- To understand neural mechanisms of tactile information processing in the human brain 

 

- Topics

- Statistical analysis of fMRI data: multi-voxel pattern analysis (MVPA) methods

- Understanding how somatosensory cortical activity varies with vibrotactile stimuli with various frequencies

- Understanding of cortical adaptation to sustained pressure stimuli

- Understanding of information flows over somatosensory cortical regions in response to pressure stimulation

- Decoding tactile information (e.g. stimulation location, texture, etc.) from BOLD signals

- Understanding of correlations between tactile sensitivity and cortical properties in individuals

- Understanding cortical mechanisms underlying tactile illusion
