Summary
Sensory perception follows a power law, but spatial neglect alters this relationship. A patient with neglect showed diminished psychophysical exponents, indicating central nervous system involvement in perception.
Area of Science:
- Psychophysics
- Neuroscience
- Cognitive Psychology
Background:
- Sensory perception is often modeled by a power law relating physical stimuli to subjective experience.
- This relationship is typically linked to peripheral sensory transduction mechanisms.
- Left-sided spatial neglect is characterized by a bias in perceiving the subjective midline.
