M6 Sensory Systems & Vision Flashcards
Sensory information that comes primarily from sources in the muscles and joints and from bodily movement is called
Proprioception
Structure located in parallel with muscle fibers that provides information about muscle length
Muscle spindle
Small stretch receptors located in the tendons that provide precise information about muscle tension
Golgi tendon organ
Information about touch is relayed from the thalamus to the
Parietal lobe
Information about audition (hearing) is relayed from the thalamus to the
Temporal lobe
TF: Information about smell is relayed from the thalamus to the occipital lobe
False
What is associated with frontal lobe (VIA)
Voluntary motor function
IQ Center
Aggression
Images expanding faster on the retina are
Approaching faster
What is the name of the variable providing optical information about time-to-contact?
Tau
Visual information, used specifically for the identification of objects within the visual environment, that is sent from the eye to the inferotemporal cortex
Ventral stream
Visual information travels from the retina to this part of the brain
Primary visual cortex
Visual information, used specifically for the control of movement within the visual environment, that is sent from the eye to the posterior partietal cortex
Dorsal stream
TF: In the Titchener-Ebbinghaus and Muller-Lyer illusions, it is the ventral stream (not the dorsal stream) that is ‘fooled’ by the illusion
True
The “Moving Room” experiments provided evidence for:
Visual dominance
Sensory information from within body
Interoceptors
Sensory information from outside the body
Exteroceptors
Vision, Hearing, Smell are examples of
Exteroceptors
Where does Afferent Information go? (3)
4 Cerebral lobes (FPTO)
Lobe dealing with touch
Parietal lobe
Lobe dealing with hearing and olfactory
Temporal lobe
Lobe dealing with vision
Occipital lobe
Frontal lobe of cerebrum & limbic system form
Intention to ACT
Receives a copy of the
motor commands sent out
to muscles (effectors) =
“efference copy” & is used as reference of comparison
Cerebellum
TEST: The 3 stages of information processing occur in which component of the closed loop control system?
Executive (control center)
Images expanding slower on retina are approaching…
Slower
Brain damage occurring to the parietal lobe (Dorsal stream)
-Able to identify objects but have difficulty interacting with them
Optic Ataxia
Brain damage occurring to the temporal lobe (Ventral stream)
-Able to interact with objects but difficulty identifying what they are
Visual Agnosia
