Memory Space Uses External Memory Like the Hippocampus
Body image utilizes the covariance of proprioception, vision, and touch. Among these, proprioception specifically employs personal space.
Personal space is divided into:
- Peripersonal space - Area within reach of the body
- Extrapersonal space - Area beyond reach
Examples:
- Peripersonal hand space (neural receptive field)
- When using tools, the receptive field expands, extending body image
The brain distinguishes between these spaces.
