Abstract:
This study used event-related fMRI to explore the neural basis of semantic involvement when performing a visually guided grasping movement. Three types of object images were presented in random order: familiar objects with handles (FH+) familiar objects without handles (FH-) and geometrical objects with a handle-like part (GH+). Subjects were then instructed to configure an appropriate hand shape for grasping the object. Common activations were found for all event types when contrasted with baseline. Activation of the anterior part of the rostral cingulate motor area was detected for only the FH+ condition and these results imply that the appropriate selection of multiple motor schemata took place in this region.

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
Sensory Perception: Organization of the Somatosensory System
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...
