We　have　developed　a　novel　tactile　pattern　presentation　device　to　assess　tactile　cognitive　function　by　active,　passive　and　dual　touch.　The　device　is　magnetic　resonance　imaging　(MRI)　compatible　and　can　serve　to　investigate　the　underlying　neural　mechanisms　of　tactile　pattern　discrimination.　The　primary　components　of　the　system　are　one　disk　for　pattern　presentation　(DPP)　driven　by　an　ultrasonic　motor,　one　set　of　fingers　position　control　unit　and　one　reaction　key　pad.　In　order　to　evaluate　the　performance　of　the　presentation　device,　two　functional　MRI　tasks　were　executed.　First,　we　used　MRI-Phantom　to　test　the　practicability　of　the　tactile　pattern　presentation　device.　Second,　we　designed　a　tactile　raised　line　cognitive　task　with　five　young　subjects　to　investigate　the　brain　activity　areas　concerning　tactile　shape　cognition　by　dual　touch.　The　results　suggested　that　this　device　to　be　unaffected　by　the　magnetic　field,　and　the　brain　imaging　results　were　consistent　with　previous　neuroimaging　study.　The　most　significantly　of　present　study　is　that　the　device　provides　a　powerful　means　of　investigating　neural　mechanisms　of　perception　and　cognitive　function　for　touch　discrimination.　©2009　IEEE.
