Study Notes
Sensation and Perception
- Sensation and Perception are distinct but related processes.
- Sensation: Sensory organs receive stimulus energy from the environment and convert (transduce) it into electrical signals that the nervous system can understand.
- Transduction: The transformation of sensory stimulus energy from the environment into neural impulses.
- Perception: The neural processing of electrical signals to create a mental representation within the brain of what is happening outside.
The Brain Perceives
- All sensory information is transduced into the same type of electrical signals, but the location of their connection to the brain determines how they are perceived.
- Ultimately, sensations merge in the brain to produce a complete perceptual experience.
