Functional and anatomical reorganization of the sensory-motor cortex after incomplete spinal cord injury in adult rats.

28 Sep 2009 A lateral hemisection injury of the cervical spinal cord results in Brown-Séquard syndrome in humans and rats. The hands/forelimbs on the injured side are rendered permanently impaired, but the legs/hindlimbs recover locomotor functions. This is ... Read more...

Repetition suppression for performed hand gestures revealed by fMRI.

30 Aug 2009 The functional components of the human motor system that are used to retrieve and execute simple intransitive hand gestures were identified with a repetition suppression (RS) paradigm. Participants performed movements with the right hand to text ... Read more...

Intentional inhibition: how the "veto-area" exerts control.

30 Aug 2009 One important aspect of self-control is refraining voluntarily from already planned behavior, by a final intervention before commitment to action. Despite its crucial role in human existence, and clear social implications, this aspect of ... Read more...
