Questions in this quiz (19)
1actions words activate the [blank_start]motor[blank_end] cortex and the [blank_start]somatosensory[blank_end] cortex
- Amotor
- Bsomatosensory
2sounds activate the [blank_start]auditory[blank_end] cortex
colours and movements activate the [blank_start]ventral[blank_end] visual stream ([blank_start]occipital[blank_end]/[blank_start]temporal[blank_end] cortex)- Aauditory
- Bventral
- Coccipital
- Dtemporal
3sensory [blank_start]functional[blank_end] theory:
-org of semantic representations is based on relevant [blank_start]sensory[blank_end] and [blank_start]motor[blank_end] features
-ex: action words activate region primary motor cortex for specific [blank_start]body[blank_end] part- Afunctional
- Bsensory
- Cmotor
- Dbody
4Domain-specific theory:
-Organization of semantic representations is based on [blank_start]semantic categories[blank_end]- Asemantic categories
5sensory/functional vs domaine-specific theory:
categories often [blank_start]correlate[blank_end] with sensory/functional distinctions- Acorrelate
6abstract semantic knowledge
-involves multiple [blank_start]modalities[blank_end] with distributed [blank_start]representations[blank_end]
-possible integrating [blank_start]hub[blank_end] in [blank_start]anterior[blank_end] (frontal) temporal lobe- Amodalities
- Brepresentations
- Canterior
- Dhub
7semantic memories usually start as [blank_start]episodic[blank_end] memories
- Aepisodic
8encoding episodic memory:
- individual parts of memory represented in [blank_start]cortex[blank_end]
-[blank_start]hippocampus[blank_end] binds representations together with assistance from the [blank_start]prefrontal cortex[blank_end] and [blank_start]posterior parietal[blank_end] cortex- Acortex
- Bhippocampus
- Cprefrontal cortex
- Dposterior parietal
9retrieval of episodic memory:
- assisted by prefrontal [blank_start]cortex[blank_end] and posterior [blank_start]parietal[blank_end] cortex the hippocampus use [blank_start]pointers[blank_end] to reinstantiate corticol representations- Acortex
- Bparietal
- Cpointers
10roles of PPC PFC during episodic encoding/retrieval:
PFC: keeping track of [blank_start]task at hand[blank_end], [blank_start]executive[blank_end] control of memory processes, [blank_start]goal[blank_end] maintenance, top-down attention
PPC: [blank_start]attentional[blank_end] control during memory processes, [blank_start]top-down[blank_end] and [blank_start]bottom-up[blank_end] attention- Atask at hand
- Bexecutive
- Cgoal
- Dattentional
- Etop-down
- Fbottom-up
11Info enters HC from all around cortex through the [blank_start]hippocampal[blank_end] pathway, goes back out through [blank_start]fornix[blank_end] to cortex (all within [blank_start]medial[blank_end] temporal lobes)
- Ahippocampal
- Bfornix
- Cmedial
12Relational memory theory:
-lesions to [blank_start]fornix[blank_end] an animal can remember basic pairs but can no longer remember [blank_start]transitive[blank_end] relationships,
HC is about linking things together in a general way- Afornix
- Btransitive
13Perirhinal cortex - [blank_start]binding[blank_end] feaures of objects
Parahippocampal cortex: encoding [blank_start]spatial[blank_end] layout
Hippocampus: Encoding [blank_start]relationships[blank_end] more generally- Abinding
- Bspatial
- Crelationships
14Hebbian Learning
-when presynapic action potential leads to postsynaptic potential, connection is [blank_start]strengthened[blank_end]
[blank_start]Early[blank_end] LTP : when strengthening occurs, increased number in NT's released which increases number od postsynaptic receptors
Late LTP: new [blank_start]synapse[blank_end] formed, wiring happens quickly more dendritic spines- Astrengthened
- BEarly
- Csynapse
15LTD: when presynaptic AP does not lead to postsynaptic AP, connection is [blank_start]weakened[blank_end]
-Reduction in NT released, number of [blank_start]receptors[blank_end] and number of [blank_start]synapses[blank_end]- Aweakened
- Breceptors
- Csynapses
16retrieval of episodic memories is [blank_start]reconstruction[blank_end]
-best guess based on:
-[blank_start]memory trace[blank_end], genes, past experience, [blank_start]internal state[blank_end], enviro context- Areconstruction
- Bmemory trace
- Cinternal state
17Amnesia:
Severe [blank_start]anterograde[blank_end] amnesia: Unable to form new LTMs after surgery
[blank_start]Temporally-graded[blank_end] retrograde amnesia: Unable to recall existing LTMs from just before the surgery- Aanterograde
- BTemporally-graded
18Consoldiation:
-New memories depend on reps in [blank_start]cortex[blank_end] and links from [blank_start]hippocampus[blank_end]
-Overtime, [blank_start]reactivation[blank_end] due to retrieval reduce [blank_start]dependence[blank_end] on hippocampus
-Old memories depend on representations and links in [blank_start]cortex[blank_end]- Acortex
- Bhippocampus
- Creactivation
- Ddependence
- Ecortex
19-Hippocampus related with [blank_start]episodic[blank_end] new memories
-Cortex relates with [blank_start]semantic[blank_end] old memories- Aepisodic
- Bsemantic
