Brain Structure
An impairment of eating, drinking, temperature regulation, or sexual behavior suggests possible damage to the _____________________.
Hypothalamus
Damage to the ventral stream may result in ________, where the individual can see objects, but not recognize them
Visual Agnosia
According to this theory, our perception of color depends on the relative activity of three types of cones.
Trichromatic Theory
This characteristic of sound waves, measured by the height of the waves, determines the intensity or loudness of a sound.
Amplitude
What would a person with conductive deafness be able to hear better than a person with nerve deafness?
Themselves talking
This is a large hindbrain structure with many deep folds. It has long been known for its contributions to the control of movement, balance and coordination, and rhythm.
Damage: clumsy and lose their balance, have trouble shifting their attention back and forth between auditory and visual stimuli
Cerebellum
These cells are responsive to stimulus at specific orientation and location.
-see box shaped, NOT complex things like faces
Simple Cells
If a kitten is raised in an environment consisting entirely of horizontal lines, later in life it:
Cannot ever see vertical lines
This snail-shaped structure of the inner ear contains the auditory receptors of hair cells. They are long tubes that are filled with fluid.
Cochlea
Occurs when peaks/valleys hit ears at different times; best for lower frequency sounds.
Phase Differences
This area of the brain is involved in movement/motion and motor learning. Damage impairs movement, as in conditions such as Parkinson's disease and Huntington's disease.
Basal Ganglia
The retina’s way of sharpening contrasts to emphasize the borders of objects. This way, we can see edges.
Lateral Inhibition
Damage to the ___________ stream of vision might interfere with reaching out to grasp an object.
Dorsal
These auditory receptors bend/move to turn into electrical activity that open channels
Hair Cells
In this theory, the basilar membrane vibrates in synch with sound causing action potentials at the same frequency. For low frequencies like these, we would look at how often they're happening rather than where.
Frequency Theory
Axons of neurons would most likely be found in which of the following?
White Matter
The ganglion cells in the fovea of humans and other primates are called _______ because each is small and responds to just a single cone
Midget Ganglion Cells
These cell types excite both horizontal and bipolar cells.
This is an inner fleshy part of the ear that gathers sound waves and helps in sound localization. It amplifies sound.
Pinna
According to the __________ theory, the basilar membrane resembles the strings of a piano in that each area along the membrane is tuned to a specific frequency.
Place
According to this law, ventral roots carry motor information while dorsal roots carry sensory information.
Bell-Magendie law
The ability to respond in limited ways to visual information without perceiving it consciously
Blindsight
This theory explains afterimages.
Opponent Process Theory
AKA eardrum, vibrates in response to sound waves at same frequency as sound waves
Tympanic membrane
These bones convert airwaves into waves of greater pressure by concentrating the force.
