A4.12
Tactile spatial resolution and cortical mapping
Cards in this group · 5
- A4.12.1Somatosensory cortex is organized by body part, not by skin surface area
- A4.12.2Fingers and lips claim cortical territory far out of proportion to their share of skin surface
- A4.12.3Cortical territory size tracks two-point discrimination acuity directly
- A4.12.4Sustained fine manipulation with one body part expands its cortical representation
- A4.12.5Cortical maps are plastic — amputation or prolonged paralysis lets neighboring representations invade the vacated territory
