- 1the basic relationship type of learning done in the cortex is calledunsupervised learning
- 2the reward learning done in the basal ganglia is calledreinforcement learning
- 3the learning with error done in the cerebellum is calledsupervised learning
- 4what two parts of the brain does spatial cognition involvehippocampus (in temporal lobe)
posterior parietal cortex - 5what does relational learning includeestablishment and retrieval of memories of events and episodes or spatial relationships (in spatial mem)
- 6what is anterograde amnesia asc. withdamage to the temporal lobe
- 7what is anterograde amnesiainability to learn new info
- 8who is a case study for anterograde amnesia and explainHM- epileptic patient, bilateral surgical removal of temporal lobe, memory of old events retained from up to 5-10yrs prior to dmg bc LTM not stored in hippoc) but new info from after was not.
- 9what does the case of HM tell ushippocampus is not location for LTMs nor for retrieval of it. not the location of immediate STMs, involved in converting immediate or STMs into LTMs
- 10what happens if your spatial memory is impairedcant navigate around town and cant find way home
- 11can the size and activity of the hippocampus increase and decrease with diff experience and what is evidence for thisyes it can. e.g. maguire london taxi drivers, strong activation of right hippomcapus correlated w driving experience when describing route bc higher spatial cog and navigation so therefore more posterior hippoc vol for storage and mental maps
- 12how many new neurons are estimated to be added to the hippoc everyday700
- 13how mnay of the adult hippoc cells are renewed or renewableone third
- 14what is the name of the evidence for the relational learning in lab animals and explainmorris water maze. opaque qater and platform so the location of it is relative to other objects,, dependent on NMDA learning and if hippocampus lesioned then rat doesnt know how to get there, but if not it can learn to swim if releeased from same place
- 15what are the special cells in the hippocampus and exactly where are theyplace cells - dorsal posterior hippocam
- 16what are place cellshave place fields where individual cells fire sequentially as rat runs on along track. tell you where abouts you are and goes in a sequence
- 17what do place cells have a role inmemory consolidation
- 18what happens in the place cells when the rat stops running the track and what does this implycells rapidly fire in reverse order, implying functional role of spontaneous (resting) activity in learning and mem consol
- 19where do the place cells get their info fed fromgrid cells
- 20specifically where are grid cellsentorhinal cortex
- 21what do grid cells do and where do they get info fromcombine diff spatial scales to activate place cells for unique locations,, receive high level spatial info from neocortex (inc. posterior parietal cortex)
- 22grid cells help usnavigate our enviro
- 23what is the hippocampus in terms of mapsallocentric- info abt environment
- 24what is the PPC in terms of mapsegocentric- relative to our position
- 25is the PPC involved in hemispheric lateralisationyes
- 26what info does the left PPC hemisphere code forinfo abt right visual field
- 27what info does the right PPC hemisphere code forboth visual fields
- 28what is the name of damage to the left parietal lobe and explain what happensapraxia
difficulty carrying our purposeful movements in absence of paralysis or muscular weakness - 29what is the name of damage to the right parietal lobe and explain what happensneglect.
difficulty in detecting or using info about items in external space - 30what is evidence for neglected info still being available in PPC damagewent to a big ol place in milan, asked to describe it and then imagine they walked to the end and turned around and they could. so hippocampus mem system intact but parietal viewpoint related retrieval was im[aired
- 31what is a saliency mapcombining visual input w attention
- 32where does the PPC sit and where does it projectsits bt sensory areas (visual, auditory, somatosensory);; projects to premotor and motor cortex and to cerebellum
- 33what are the four sub divisions of the PPCeye movement
spatial coding
reaching and pointing
grasping - 34when planning actions, what two things are needed to be combinedretinal / eye position signals WITH tactile visual and auditory signals
- 35what is the name of the sulcus in the middle of the parietal lobeintra parietal sulcus
- 36when you open up the intra parietal sulcus what four things do you findlateral inter parietal area (LIP)
medial inter parietal area (MIP)
anterior inter parietal area (AIP)
ventral inter parietal area (VIP) - 37what does the LIP dopredictive remapping of parietal receptive fields and about intended eye movements, it responds before the stim arrives in the rf. provide updates of attention to final eye position before saccade starts
- 38what does the VIP doencodes space and motion around your head, looks at receptive fields in near space, responds to looming visual or auditory stimuli
- 39what does the MIP doreaching and pointing. (if this is affected if her arm moved she could see it but feel like it hasnt moved) involved in updating of body schema and illusions of it too
- 40what does the AIP dograsping, produces a map which would activate when grasping and active touch. reacts differntly to diff hand postures.
- 41what is the name of the illness where you dont know your arm has moved and struggle graspingoptic ataxia
- 42what is motor cognition broadlyconcerned with understanding action representations and associated with higher mental processes
