To help us learn about the environment
Which term describes the process of converting different types of stimuli into electrochemical signals?
Sensory transduction
What happens when a stimulus is detected by a receptor?
A graded potential is generated in a sensory neuron
What is the result of central integration of sensory information?
Conscious perception of the stimulus
What is the difference between sensation and perception?
Sensation is the activation of sensory receptors, while perception is the central process
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.
