Primary sensory cortex
The area of the cortex that receives direct input directly from the thalamic relay nuclei of one sensory system.
Secondary sensory cortex
Areas of cerebral cortex that receive most of their input from primary visual cortex.
Association cortex
Any area of the cortex that receives input from more than one sensory system.
Hierarchical organization
Organization into a series of levels that can be ranked with respect to one another; for example, primary cortex, secondary cortex, and association cortex become more and more complex.
Sensation
The process of detecting stimuli.
Perception
The higher-order process of integrating, recognizing, and interpreting complex patterns of sensations.
Functional segretation
Organization into different areas, each iof which performas a different function; for example, in sensory systems, different areas of secondary and assocation cortex analyze different aspects of the same sensory stimulus.
Parallel processing
The simultaneous analysis of a signal in different ways by the multiple parallel pathways of a neural network.
Fourier analysis
A mathematical procedure for breaking down a complex wave form into component sine waves of varying frequency.
Tympanic membrane
The eardrum.
Ossicles
The three small bones of the middle ear; the:
1. malleus
2. incus
3. stapes.
1. malleus
2. incus
3. stapes.
Oval window
The membrane that transfers vibrations from the ossicles to the fluid of the choclea.
Choclea
The long coiled tube in the inner ear that is filled with fluid and contains the organ of Corti and its auditory receptors.
Organ of Corti
The auditory receptor organ, comprised of the basilar membrane, the hair cells, and the tectorial membrane.
Hair cells
The receptors of the auditory system.
Basilar membrane
The membrane of the organ of Corti in which the hair cell receptors are embedded.
Tectorial membrane
The cochlear membrane that rests on the hair cells
Auditory nerve
The branch of cranial nerve VIII that carries auditory signals from the hair cells in the basilar membrane.
Retinotopic
Organized like the primary visual cortex, according to a map of the retina.
Tonotopic
Organized, like the primary auditory cortex, according to the frequency of sound.
Semicircular canals
The recptive organs of the vestibular system.
Vestibular system
The sensory system that detects changes in the diurection and intensity of head movements and that contributes to the maintenance of balance through its output to the motor system.
Superior olives
Medullary nuclei that play a role in sound localization
Inferior colliculi
The structures of the tectum that receive auditory input from the superior olives.
Medial geniculate uclei
The auditory thalamic nuclei that receive input from the inferior colliculi and project to primary auditory cortex.
Tinnitus
Ringing in the ears.
