6. Which of these is NOT true of hippocampus function re; memory?

  • Receives connections from only auditory and visual sites
  • Receives connections from ALL modalities (e.g auditory, visual, smell, emotion)
  • Contains multiple nested feedback loops (associative learning)
  • Neurons have special properties supporting memory (e.g LTP)

7. Which of these is NOT a key theory of hippocampal coding?

  • Redintegration theory
  • Recollection v.s familiarity
  • Cognitive maps
  • Relational memory

8. In a study of transgenic mice, what was impaired when NMDA receptors on CA1 were knocked out?

  • Classical learning
  • Semantic memory
  • Spatial learning
  • Semantic memory and position encoding

9. What makes hippocampal cells special for LTP?

  • The synapses at the hippocampus are divided, containing more dendritic spines to enhance LTP
  • Large CA output @ the CA1 and CA3 receptors
  • Large amount of NMDA receptors @ the CA1 and CA3 synapses
  • Dopamine release is triggered by LTP

10. Which of these acts importantly in spatial layout coding?

  • Rhinal sulcus
  • Perirhinal cortex
  • Parahippocampal cortex
  • Entorhinal cortex

11. Where does the hippocampus receive its input?

  • Rhinal sulcus
  • Dendate gyrus
  • Subiculum
  • Amygdala

12. Which of these is NOT a change driven by LTP maintenance at the synapse?

  • Decrease in receptor density
  • Divided synapse
  • Increase in receptor density
  • Enlarged synapse
  • Formation of new dendritic spines

13. How do NMDA receptors facilitate LTP?

  • NMDA expel MG2+ from the channel, creating a greater influx of NA and CA and a lower action potential
  • NMDA expel MG2+ from the channel, creating a greater influx of NA and CA and a greater action potential
  • NMDA expel glutamate from the channel, creating a greater influx of NA and CA and a greater action potential
  • NMDA expel MG2+ from the channel, creating a greater influx of glutamate and a greater action potential

14. Which of these acts importantly in object recognition?

  • Entorhinal cortex
  • Perirhinal cortex
  • Parahippocampal cortex
  • Rhinal sulcus

15. According to Hebb (1949), what is LTM a result of?

  • Neural networking
  • Structural modification of cell assemblies
  • Structural changes in cell axons and synapse
  • Multiple nested feedback loops

16. Which of these characterises cognitive maps re; coding in the hippocampus?

  • The hippocampus provides a internal map coding for spatial relations between objects in the environment
  • Relational frameworks can be disassociated from associations. e.g can learn which cup was rewarded with food, but couldnt infer the BEST cup to search if one was rewarded more than another
  • A unique role of the hippocampus in mental time travel, recollection involves relations between items and contexts v.s familiarity = declarative memory

17. Within the hippocampus, what are the main cell fields called?

  • CA3 only
  • B1 and B3
  • CA1 and CA3
  • CA1 only

18. In the anterior/posterior gradient of the hippocampus, what does the anterior cortex receive more input from?

  • The parahippocampal cortex, it has more place cells
  • The amygdala and perirhinal cortex, encodes emotional memories and item familiarity/salience
  • The entorhinal cortex, it has more place cells
  • The amygdala and entorhinal cortex, encodes emotional memories and item familiarity/salience

19. What feature of LTP makes memory durable?

  • Synaptic consolidation
  • Single high frequency train induction
  • Specificity
  • Associativity

20. Which of these characterises relational memory re; hippocampal coding?

  • Relational frameworks can be disassociated from associations. e.g can learn which cup was rewarded with food, but couldnt infer the BEST cup to search if one was rewarded more than another
  • A unique role of the hippocampus in mental time travel, recollection involves relations between items and contexts v.s familiarity = declarative memory
  • The hippocampus provides a internal map coding for spatial relations between objects in the environment
