Memory Formation Research
@@Home -> NeoCortexResearch -> MemoryFormation
Memory Prediction research covers using HTM/Memory Prediction theory for memorizing and recognizing complex patterns, produce internal representation.
Terms
- short-term memory - lasts for max 18 seconds
- long-term memory - lasts for day or years (undergo forgetting process) - declarative and procedural
- declarative memory - all memories that are consciously available - episodic and semantic
- episodic memory - memory for specific events in time
- semantic memory - knowledge about the external world
- procedural memory - how to perform certain motor behaviour
Long-term memory (LTM)
as per Wikipedia:
- declarative memory - encoded by hippocampus (also by enthorinal and perirhinal) but consolidated somewhere else - probably in temporal cortex
- procedural memory - encoded and probably stored in cerebellum / striatum
- emotional memory - related to amygdala
Sensory Neocortex
- recognize and predict functions, as per Jeff Hawkins
- long-term memory formation by hippocampus - how it is related to neocortex?
- do we have short-term memory in neocortex?
Current Understanding:
- information is supplied by discrete events (not as ongoing flow) - e.g. saccades, which supply fragmentary information to visual neocortex 3 times per second
- neocortex holds generalization structures, averaged perceived information, not episodic memory
- association cortex and frontal cortex (holds feelings) supply feedback via cingulate gyrus to sensory cortex and hippocampus
- associations and emotionally stressed data are stored easier
- temporal cortex (TC) lies between visual sensory cortex (VC) and hippocampus (HC)
- LTM is not stored by hippocampus, but hippocampus is absolutely required to create LTM as per HM patient
- hippocampus is not required to keep short-term memory (18 seconds)
- most appropriate place for LTM is temporal cortex
- VC perceives primary sensory information and transforms to stable internal representation
- VC -> TC flow supplies flow of internal representations, or signal of inability to recognize/predict; TC -> VC is unclear
- HC -> TC flow represents control of memorising by hippocampus
