- How the Brain Acquires new Memories
- Key Brain Regions
- Hippocampus
- Staresina & Davachi (2009). Combined, spatial discontiguous or spatiotemporally discontiguous.
- The spatiotemporally condition showed the most hippocampaldemands.
- Perirhinal cortex shows subsequent memory effects for object recognition
- The spatiotemporally condition showed the most hippocampaldemands.
- Staresina & Davachi (2009). Combined, spatial discontiguous or spatiotemporally discontiguous.
- PFC
- Otten et al (2009). LoP task. Activity in left IFG for SME for the deep condition rather than shallow.
- Blumenfeld and Ranganath 2007) PFC shows greater activity when items successfully remembered, not when forgotten
- Otten et al (2009). LoP task. Activity in left IFG for SME for the deep condition rather than shallow.
- Parietalcortex
- Uncapher et al (2009). Dorsal parietal recruited for remembered items (top down attention). Increased ventral parietalactivity for forgotten items.
- Hippocampus
- Models of memory acquistion
- Learning and memory in aplasia
- Maze learningmice
- Eye blink conditioning in rabbits
- Hand-eye coordination in monkeys
- Spatial navigation in taxidrivers.
- How to study memory encoding
- Subsequent memory paradigm: record activation for words remembered vs words forgotten. DDM = R - F
- Pattern seperation: Seperate disctinct items that make up a memory
- Pattern completion: partial activation reactivates the pattern of activity that occurred when experienced an episode.
- Brain Oscillations
- Gamma(40Hz)
- Markram et al (1997). The increase in coplingbetween cells when stimulated simultaneouslyStimulating in gamma range achieves greater degree of LTp.
- Sederberg et al (2008). Intracranial EEG. Patients show gamma activity in hippocampus for subsequently remembered items.
- Jutras et al., (2009) Monkeys show more recognition of an item through eye gaze also show high gammaactivity in hippocampus.
- Fell et al., 2001). Higher gamma synchrony between rhinal cortex and hippocampus for later remembered vs forgotten items.
- Jutras et al., (2009) Monkeys show more recognition of an item through eye gaze also show high gammaactivity in hippocampus.
- Sederberg et al (2008). Intracranial EEG. Patients show gamma activity in hippocampus for subsequently remembered items.
- Markram et al (1997). The increase in coplingbetween cells when stimulated simultaneouslyStimulating in gamma range achieves greater degree of LTp.
