Summary[edit]
| Summary | |
|---|---|
| Description | Map of the body in the human brain. The cerebral cortex has been “inflated” to show the results more clearly. Movements of different body parts evoked activity in the primary motor cortex (left of the central sulcus, shown by the arrow) and primary somatosensory cortex (right of the central sulcus). The map also shows eye-movement activity in the frontal eye field and the parietal cortex. The map is a winner-take-all. Although different body parts activated overlapping areas of cortex, only the strongest activations are indicated. The map in the primary motor cortex contains two common complexities. First, the hand representation (red) is surrounded on three sides by a representation of the wrist. Second, there are two distinct hand representations possibly corresponding to areas 4a and 4p. |
