Intro to Perception
Term for using previous knowledge to interpret sensory information
What is top-down processing?
Part of the neuron that receives incoming signals
What is dendrite?
The type of photoreceptor that is responsible for color vision and functions best in bright light
What are cones?
The specific area of the retina that elicits a response from a neuron
What is receptive field?
The ability to recognize objects from different angles
What is viewpoint invariance?
Term for the lowest detectable stimulus intensity
What is absolute threshold?
The endpoint of an axon where signals are transmitted to the next neuron
What is axon terminal?
The bundle of axons of retinal ganglion cells
What is optic nerve?
The brain structure that relays visual information from the retina to the cortex
What is lateral geniculate nucleus (LGN)?
The perceptual principle suggesting elements close to each other are perceived as a group
What is principle of proximity?
The lobe of the cortex that is primarily responsible for high-level functions like planning and reasoning
What is the frontal lobe?
The electrical impulse that travels down an axon, leading to the release of neurotransmitters
What is action potential?
The process of adjusting the thickness of the eye lens to bring objects into focus
What is accommodation?
The cell type in the visual cortex that responds best to movement in a specific direction
What is complex cell?
The inability to recognize faces despite having intact visual acuity
What is prosopagnosia?
The term for the image projected onto the retina from the environment
What is proximal stimulus?
The short period after an action potential during which a neuron cannot fire another one
What is refractory period?
The closest distance at which an object can be seen clearly by the eye
What is near point?
The process by which sensory receptors become less responsive to constant stimuli
What is adaptation?
The area in the brain associated with processing body parts
What is extrastriate body area (EBA)?
The specialized neurons that respond to specific types of environmental energy
What are sensory receptors?
The junction between two neurons where information is transmitted from one to another
What is synapse?
The two components of visual pigment molecules found in photoreceptors
What are opsin and retinal?
Refers to the fact that the fovea is represented by a larger area in the visual cortex compared to peripheral vision
What is cortical magnification factor>
The process of interpreting brain activity patterns to infer thoughts or images
What is neural mind reading?
