lecture 20 Flashcards
temporal lobe
which cortex are included in the temporal lobe
neocortxe, limbic cortex, and olfactory
subcortical structures of the temporal lobe
amygdala and hippocampus
sulci and gyri of the temporal lobe
(top to bottom)
sylvian fissure, superior temporal gyrus, superior temporal sulcus, middle temporal gyrus, inferior temporal sulcus, inferior temporal gyrus
auditory and visual area location
auditory is superior, visual is inferior
what is the temporo-parietal junction involved in
attention, memory, and social decision making
where is the insula
deep within the sylvian fissure
where is the pyriform cortex and what is it associated with
anterior, superior, medial part of temporal lobe, olfactory sense
where do sensory systems project to
the temporal lobe
where does output from the temporal lobe go to
the frontal and parietal lobes, plus the limbic system and basal ganglia
where does visual and auditory info project to and what does it support
medial temporal lobe, long-term memory
what are hierarchical visual and auditory pathways used for
object recognition
____ auditory pathways dircet movements in response to ____ info
dorsal, auditory
what pathways support object categorization in the STS
polymodal visual and auditory
pathways to the frontal lobe are important for what
motor control and short term memory
____ projections to the ____ are important for odor perception and memory
olfactory bulb, pyriform cortex
the temporal lobe is important for analyzing what kind of info
sensory
the temporal lobe does ____
(4 things)
auditory input processing, visual object recognition, long-term memory storage, olfactory input processing
why/how does attention shift
deciding what feature is most relevant
what makes for accurate perception and memory
being able to quickly categorize objects
what can damage to the temporal lobe result in
defecits in identifying nd catgeorizing stimuli
what does cross-modal matching enable
integration of visual and audiotyr info, likely involves the STS
where is sensory input combined and stored
sturtcures of the medial temporal lobe
what is the affective response
the subjective feeling about a stimulus
what structure does the affective response involve
the amygdala in the medial temporal lobe
what does the affective repsonse do
associates the stimulus with positive, negative, or neutral consequences
damage to the amygdala results in what
inability to have an emotional repsonse to threatening stimuli
what does the hippocampus contain
place cells to encode location in space, and support navigation
what does the superior temporal sulcus do
detects biological motion, movement relevant to the species
why is it important to detect biological motion
understanding intentions of others
what types of bilogical motion does the STS detect
body motion, facial movement, voice cues
cells in STS are sensitive to what
mouth movements and vocal characteristics, other cells are sensitive to motion in certain directions or specific facial expressions
fusiform face area vs sts face area
fusiform - invariant (unchanging) - identity, gender, form
sts face area - changeable - expression/gaze, motion
what activates different combos of cells in TE
overall features objects possess, combos of orientation, size, colour, and texture
____ and ____ alter response patterns of TE neurons
experience and training
neurons in the TE area form ____ that respond to ____
cortica columns, categories of shapes
T/F
some cells responf selectively to facial identity, and some to expression
true
there are specific cortical regions within the ____ and ____ lobes involved in recognizing ____ faces
occipital, temporal, upright
lesions to the ____ temporal lobe have a greater impact on the ability to process faces than to the other side
right
