V1 is an exact copy of the retina. What is one difference between simple cells and complex cells? a. A
simple cell responds to all wavelengths
whereas complex cells respond only to wavelengths in their particular wavelength tuning.
What is the name of area in the Inferotemporal area of the temporal lobe that specializes in recognizing familiar faces group of answer choices?
The fusiform face area (FFA, meaning spindle-shaped face area)
is a part of the human visual system (while also activated in people blind from birth) that is specialized for facial recognition. It is located in the inferior temporal cortex (IT), in the fusiform gyrus (Brodmann area 37).
What is the relationship between V1 and the retina quizlet?
What is the relationship between V1 and the retina?
V1 contains a map of the retina
. What is one difference between simple cells and complex cells? A complex cell will respond to a dark bar on a light background and a light bar on a dark background, but a simple cell will only respond to one or the other.
What term refers to an acquired deficit in identifying and recognizing objects even though vision remains intact?
From Wikipedia, the free encyclopedia. Visual agnosia is an impairment in recognition of visually presented objects.
What is one difference between simple cells and complex cells quizlet?
complex cells have no inhibitory surround.
Simple cells have separate excitatory and inhibitory zones
. Both found in primary visual cortex (V1), both are orientation-selective cells. what is a special type of complex cell?
What is the pathway and where pathway?
In the currently prevailing view, the different maps are organised hierarchically into two major pathways, one involved in recognition and memory (the
ventral stream
or ‘what’ pathway) and the other in the programming of action (the dorsal stream or ‘where’ pathway).
Why do humans perceive faint light better in the periphery of the eye?
Why do humans perceive faint light better in the periphery of the eye? a.
Receptors in the periphery are closer to the pupil
. … More receptors in the periphery than in the fovea funnel input to each ganglion cell.
Which side of the brain recognizes faces?
It is suggested that any
greater right hemisphere
involvement in the recognition of upright faces is due to our greater expertise at recognizing faces than other stimulus types.
Does the FFA receive information from other brain regions?
Indeed,
the OFA appears to receive information early from the visual cortex
before being analyzed by higher cortical areas. Along these same lines, the OFA has been implicated to be involved in processing fluid physical face changes, rather than more static identity cues.
What part of the brain matches faces to names?
There is a part of the brain dedicated to recognising faces – called
the Fusiform Face Area
– positioned in the part of the brain called the Temporal Lobe, which can be found roughly in the area behind your ears.
What are the two pathways of visual streams for visual processing in the human brain?
The
ventral stream (or “vision-for-perception” pathway)
is believed to mainly subserve recognition and discrimination of visual shapes and objects, whereas the dorsal stream (or “vision-for-action” pathway) has been primarily associated with visually guided reaching and grasping based on the moment-to-moment analysis …
What are the what pathways of the brain?
As visual information exits the occipital lobe, and as sound leaves the phonological network, it follows two main pathways, or “streams”. The
ventral stream
(also known as the “what pathway”) leads to the temporal lobe, which is involved with object and visual identification and recognition.
What are color blobs?
Blobs are
sections of the visual cortex where groups of neurons that are sensitive to color assemble in cylindrical shapes
. They were first identified in 1979 by Margaret Wong-Riley when she used a cytochrome oxidase stain, from which they get their name. … Blobs are on the parvocellular pathway.
What is one difference between simple cells and complex cells?
But, unlike simple cells,
they respond to a variety of stimuli across different locations
. For example, a complex cell will respond to a dark bar on a light background and a light bar on a dark background. In contrast, a simple cell only responds to one but not the other.
What is visual agnosia quizlet?
Visual agnosia.
The inability to perceive or identify a stimulus, despite normal vision sensation
. You just studied 6 terms!
What is the difference in function between simple cells and complex cells in the visual cortex quizlet?
Understand the difference between simple cells and complex cells. Like simple cells, each complex cell is tuned to
a particular orientation and spatial frequency and show ocular preference
. 2. Know how the same stimulus can results in different patterns of responses for simple and complex cells.
