Chad is reading when he sees an insect land on the corner of his book. He then makes an eye movement to look at the insect. The structure of the visual system that is most likely responsible for making this eye movement is:
A) the extrastriate cortex.
B)
C - The superior colliculus
The flow of information in the LGN is best described as:
A) unidirectional, with signals going from the LGN to the retina.
B) unidirectional, with signals going from the LGN to the cortex.
C) unidirectional, with signals going from the retina to the LGN.
D - BI-Directional, with signals coming from the retina and the cortex to the LGN
Graphing the response of a simple cortical cell results in the:
A) orientation tuning curve.
B) response compression curve.
C) motion-directive sensitivity function.
D) response expansion curve.
A - Orientation tuning curve
When you stare at a grating of wide bars for 55 seconds, then look at a grating with narrow bars, the narrow bars will:
A) seem to change orientation.
B) be unaffected by the adaptation period.
C) seem to be thinner than they actually are.
D) seem to be w
C - seem to be thinner than they are
When a kitten is exposed to an environment of just horizontal lines, the kitten:
A) would pay attention only to horizontal lines.
B) would have cortical cells that only respond to vertical lines.
C) would have cortical cells that respond to horizontal lin
C - Would have cortical cells that respond to horizontal line, but none to verticle line
Object discrimination problem: ________. Landmark discrimination problem :________.
A) temporal lobe; parietal lobe
B) parietal lobes; temporal lobes
C) parietal lobes; occipital lobes
D) LGN; thalamus
A - temporal lobe; parietal lobe
The tilted frame in the rod-and-frame test influenced the alignment of the rod in the ________ task(s).
A) neither matching, nor grasping
B) grasping
C) both matching and grasping
D) matching
D - matching
An area in the ________ called the ________ is specialized to recognize faces.
A) occipital lobe; RBC
B) parietal lobe; area 4H
C) parietal lobe; FFA
D) temporal lobe; FFA
D - temporal lobe; FFA
After training participants on the recognition of "Greeble" stimuli, Gauthier et al. found that the neuron in the FFA responded:
A) weakly to Greebles, but strong activity to human faces.
B) unpredictably to Greebles, and inhibited activity for human face
C - as well to Greebles as to human faces
The area on the retina that influences the firing rate of the neuron is called the
receptive field
A neuron with an excitatory center- inhibitory surround receptive field will respond most when we stimulate
only the center
center-surround receptive field occur in neurons
for both skin senses and vision
grandmother cells" are mostly associated with ____ coding
specificity
An advantage of __________ coding of visual object representation is that a large number of stimuli can be signaled by a few neurons.
disturbed
A neuron studied by Quiroga et al. studied sensory coding by
using implanted electrodes in the hippocampus of epileptic patients
A neuron studied by Quiroga et. al responded to
(a photograph of Halle Berry's face, a photograph of halle berry dressed as cat woman, the word "halle berry" physically represented)
All of these caused the cell to fire.
____ reacts to light to start the process of transduction
retinal
What are single and double dissociation?
Single dissociation: Feature A is present, but feature b is not, but the two functions are not independent from one another. Example: hypnosis.
Double dissociation: Feature A is present, feature B is not, and they are independent from one another. Example
What are brain maps and modules? give an example.
Retinotopic map: correspondence between points on the LGN and the point on the retina creates a retinotopic map. Example:Looking at points A, B, and C on a cup where they line up within the eye.
Modules: neurons that respond to similar stimuli are often g
