Study Notes
Afterimages
- Afterimages are visual sensations that persist for a short duration after the removal of the original visual stimulus.
Opponent-Process Theory
- This theory explains color vision through opposing retinal processes, such as red-green and yellow-blue.
- Certain retinal cells can be activated by one color while being inhibited by its opponent color.
Hertz
- Hertz (Hz) is a unit of frequency, representing cycles per second.
Pinna
- The pinna is the visible external part of the ear, made of cartilage, and plays a role in capturing sound waves.
Auditory Canal
- The auditory canal is the passage in the outer ear that extends from the auricle to the tympanic membrane (eardrum).
Cochlea
- The cochlea is a spiral-shaped structure in the inner ear that converts sound vibrations into nerve impulses.
- It contains the Organ of Corti, which is essential for hearing.
Auditory Nerve
- The auditory nerve carries auditory information from the inner ear to the brain, facilitating the perception of sound.
Pitch
- Pitch is the auditory quality that allows the distinction between different frequencies of sound; it varies with the frequency of vibration.
Place Theory
- The place theory correlates the pitch of sound with the specific location of stimulation along the cochlea's membrane.
Volley Principle
- The Volley Principle describes how groups of nerve cells work together to encode sound information through action potentials.
- It addresses the limitation of individual neurons that can produce action potentials only at lower frequencies (300-500 Hz), allowing for multiple neurons to alternately send signals for higher frequencies.
Frequency Theory
- According to frequency theory, hair cell receptors vibrate at the same frequency as incoming sound waves, contributing to sound perception.
