Study Notes
Sensation and Perception
- Sensation refers to the process of detecting and encoding environmental stimuli, such as light, sound, and touch, into neural signals.
Receptors in the Sensory System
- The main function of receptors in the sensory system is to convert environmental stimuli into neural signals that can be interpreted by the brain.
Dark Adaptation
- The purpose of dark adaptation is to allow the eyes to adjust to changes in light levels, enabling us to see in low-light environments.
- Dark adaptation occurs when the pupils dilate and the concentration of rhodopsin (a light-sensitive pigment) in the rod cells of the retina increases.
Light Striking the Retina
- When light strikes the retina, it activates the photoreceptors (rods and cones) to send neural signals to the brain, which interprets these signals as visual information.
Theories of Color Vision
- The three theories of color vision (Trichromatic, Opponent Process, and Retinex) attempt to explain how the brain processes color information from the visual stimuli detected by the retina.
- These theories propose different mechanisms for how the brain interprets the signals from the retina to create our subjective experience of color.
