Kahoot Questions 1 (principles - vision - attention) Flashcards
Cognitive neuroscience primarily bridges between neuroscience and psychology.
True or False
True
Cognitive neuroscience predominantly focuses on clinical populations.
true or false
false
Cognitive neuroscience aims to understand neural realisation of cognitive functions in the level of…
large-scale networks.
The two substances described in Cartesian ontology area:
res extensa and res cogitans
Descartes’s res extensa denotes the mental substance and the thinking soul.
true or false
False
According to Descartes, the sear of the soul and consciousness is in the…
pineal gland.
Equipotentiality is another term for phrenology.
true or false
false (should be Holism, I assume)
According to holism, cerebral cortex function as
an indivisible whole.
the father of Phrenology is…
Franz Joseph Gall.
Patients with Broca’s aphasia have:
compromised speech production and intact speech perception. (“tan, tan”)
Representation of body parts are differently sized in the motor and sensory homunculus.
True or False
True.
Invasive recordings are always more scientifically interesting than non-invasive imaging
True or False
False.
Contemporary cognitive neuroscience conceptualizes structure-function mapping as:…
non-sparse.
Evidences of double dissociation is a final proof of independence of certain cognitive functions and their substrates.
True or False
False.
What is a distal sense?
Hearing
When the ciliary muscles of the eye are relaxed, the lense is accommodated to view objects in the distance.
True or False
True
A translucent part of the eye that gets hit by light first and where most of the light refracts is called the…
cornea.
The retina is the part of eye where…
light gets transformed into neural activity.
Photoreceptors in the human retina are located at the front of retina – where the light first hits the retina.
False.
Lateral processing in the retina is performed by:…
amacrine and horizontal cells
The blind spot is a consequence of an inverted retina.
True or False
True ?
(I thought it is, because the optic nerve enters the retina at that spot, can somebody clarify?)
A: I think it depends on how you interpret “inverted” i.e. whole image inversion or because of photorecptors and ganglion cells dangling around at the wrong side.
Which cells fire action potentials?
Ganglion cells
The optic nerve leads from ganglion cells of the retina into:…
the thalamus
How many types of photoreceptors exist in a healthy human retina?
4 types
One cone photoreceptor always feeds into one ganglion cell.
True or False
False
Receptive fields in the LGN have an excitatory and inhibitory region, therefore coding for contrast.
True
An on-center ganglion cell will respond the strongest if we shine the light:
only on its center
After the optic chiasm, the left optic tract contains information from both left and right visual hemifield.
True or False.
False
Which types of cells we do not find in V1?
Icecube cells
Complex cells can respond to a line of their preferred orientation anywhere in their receptive field.
True or False
False
Cells in the V1 that preferentially fire for a certain line orientation are grouped into:…
orientation columns
Lower-level visual areas are located in and around the…
calcarine sulcus
In V1, the visual field is represented with both vertical (left to right) and horizontal (upper to lower) inversion. True or False
True
Visual scene information in V2 and V3 is separated into quarter-fields.
True
Visual information does not necessarily need to travel through … to get to V1.
the superior colliculus
Area V5 is believed to process color.
True or False
False
Which are the two main visual processing pathways?
Ventral and Dorsal
Receptive fields of neurons in medial temporal lobe(MTL) of left hemisphere capture which part of the visual field?
Most of the field
Top-down attention is guided by endogenous cues.
True or False
True
What is exogenous or bottom-up visual attention?
The capture of attention by salient features
During visual covert attention, gaze and attention are coupled.
False
Top-down attention is neurally regulated by:
frontaparietal network
In Posner cueing task, reactions are the slowest(reaction times longest) in:
invalid trials.
Broadbent’s filter model is a late selection model: True or False
False
In early selection models of attention, stimulus is selected further processing:
before perceptual analysis of the stimulus is complete.
A characteristics of serial visual search is that it:
requires attention
Serial visual search relies on the pop-out effect
False.
