Tool-use: An open window into body representation and its plasticity

Figures & data

Table 1. Criteria used to qualify bodily and spatial representations.

	Peripersonal space	Body schema	Body image	Body structural description
Sensory inputs	Multisensory (vision, audition, touch, vestibular)	Proprioception Kinesthesis Touch	Multisensory (vision, audition)	Vision Verbal Somatosensory
Format	Multisensorimotor	Somatosensorimotor	Visuospatial	Visuospatial
Functional properties	Defensive movements Appetitive actions	Metric body knowledge for action (body parts’ position and size)	Body percept, concept, and affect; Visual metrics of the body	Structural information about body parts location
Accessibility	Mainly unconscious	Mainly unconscious	Conscious	Conscious

Note: Here we subdivide the body and space representation according to different criteria – namely, sensory inputs, format, functional properties and accessibility.
