Study Notes
Sensory Receptors
- Sensory receptors are specialized cells or organs that detect and respond to specific stimuli from the environment, such as light, sound, touch, temperature, and chemicals.
Transduction
- Transduction is the process of converting different types of stimuli into electrochemical signals that can be interpreted by the nervous system.
Stimulus Detection
- When a stimulus is detected by a receptor, it triggers a chemical signal that travels to the nervous system, where it is interpreted and processed.
Central Integration
- The result of central integration of sensory information is the creation of a meaningful perception of the world, which is influenced by past experiences, emotions, and attention.
Sensation vs. Perception
- Sensation refers to the detection of raw sensory information by receptors, whereas perception is the interpretation and understanding of that information, resulting in a meaningful and conscious experience.
