Module 5 sensation & perception Flashcards
The process through which the lens changes shape to bring objects into focus on the retina
Accommodation
the location in the temporal lobe where auditory information is processed.
auditory cortex
The tissue inside the cochlea where the hair cells are located
Basilar membrane
Auditory cues that require comparisons from both ears to understand an object’s location
Binaural cues
These cues require comparing an image as it falls on both eyes in order to understand how far away an object is from the viewer
Binocular depth cues
The processing of physical messages delivered to the senses
Bottom-up processing
Sensory cells in the nose that respond to air molecules that we interpret as smell and taste
Chemoreceptors
A snail-shaped structure in the inner ear where the auditory hair cells are located
Chochlea
Cells in the visual striate cortex that respond to lines of specific orientations in motion
Complex cells
A type of photoreceptor in the retina that is typically most responsive to bright lighting conditions and is responsible for communicating information about acuity and color
cone
A term for several rare conditions where an individual is unable to experience pain
Congenital Analgesia
The transparent covering of the eye; performs about 80% of the focusing of a visual image
cornea
Part of the bipolar layer of the retina. These cells receive signals from the rods and send their messages to large (magno) ganglion cells
Diffuse bipolar cells
Also known as the Where stream, this pathway takes information from the occipital lobe to the parietal lobe, where we are able to identify object location
dorsal stream
Specialized cells in the visual cortex that respond most actively to specific stimuli
feature detectors
he portion of the retina directly behind the pupil. It contains a large concentration of cones and no rods
fovea
The physical measurement of pitch, or how high/low a sound is. It is measured in Hertz (Hz)
frequency
The theory of audition that suggests we understand pitch because of the rate of cellular firing on the basilar membrane
frequenct theory
A theory of pain perception that suggests that painful stimuli can be blocked in the spinal cord when you are engaged in other activities
Gate-control theory of pain
The sensory neurons inside the inner ear that convert sound into neural firing
Hair cells (auditory)
The sensory neurons inside the vestibular sacs that convert information about gravity into neural firing
hair cells (vestibular)
The physical measurement of the loudness of a sound. This is measured in decibels (dB)
Intensity
The brain compares intensity differences of sound as it arrives at each ear in order to understand object location
interaural level difference
Comparisons made between the small differences in arrival time of a sound in each ear
interaural time differences
Also known as an earworm, it is the auditory experience of an inability to dislodge a song from one’s consciousness
involuntary musical imagery
The ring of pigmented tissue surrounding the pupil. The iris is responsible for controlling the diameter and size of the pupil, thereby controlling the amount of light that reaches the retina
iris
This term refers to our sense of where our bodies are in space and how to move the body to accomplish specific tasks
kinesthetic sense
Part of the ganglion layer of the retina. Receive signals from the diffuse bipolar cells. The axons of these cells leave the eye and form part of the optic nerve. Also known as magno cells
large ganglion cells
he 6-layered portion of the thalamus that processes and organizes visual information
lateral geniculate nucleus
