NE202: Lecture #18 - Memory (Pt. 3) | Ch. 9
Adapted notes from Dr. David Somers' 18th lecture (Thursday, April 1, 2021) for CAS NE202 at Boston University for the spring semester of 2021
Terms in this set (16)
A neurodegenerative disease that resembles Patient H.M.'s condition in the broad sense. This disease causes degenerative memory loss, which diffuse damage in the brain. However, the MTLs degenerate early.
(True or False) MRI and PET scans can reveal MCI prior to AD diagnosis (if they do develop AD or some other type of dementia, if at all). It is also important to note that MCI is not dementia quite yet.
The one thing that seems protective against AD.
- Entorhinal/perirhinal cortex
What are the key structures within the MTLs?
- Cognitive map theory (O'Keefe & Nadel)
- Relational memory theory (Eichenbaum & Cohen)
- Episodic memory theory (Tulving)
What are the three theories of hippocampal memory function? Can these three be commensurate?
Cognitive Map Theory (O'Keefe & Nadel)
A theory of hippocampal memory function that posits that the hippocampus serves as a cognitive spatial map. This theory highlights a role for
, which fire for a particular location.
Relational Memory Theory (Eichenbaum & Cohen)
A theory of hippocampal memory function that posits that the hippocampus serves the general purpose of mediating new associations (not just spaces/places, like it is posited to do in the
cognitive map theory
). This places the HPC as the re-joining point of the dorsal (paraHPC) and ventral (perirhinal) streams, with the HPC sitting at the top of the hierarchy, giving it the role of
Episodic Memory Theory (Tulving)
A theory of hippocampal memory function that posits that the hippocampus functions for episodic, not semantic memories.
(True or False) The
cognitive map theory
has won a Nobel Prize.
A neuron that selectively fires when the animal crosses the intersection points of an abstract grid map of the local environment. This type of cell is found in the entorhinal cortex.
- Cereal treats were placed in one of two beakers filled with sand
- The sand was scented
- Only non-lesioned rats were able to correctly pick the treat beaker across predetermined pairs, thus only they learned
Describe the experiment that lent support to the
relational memory theory
A neurological patient who had more extensive brain damage than H.M. (MTLs, dorsolateral PFC, OC, PC) and retrograde (>10 years; all episodic lost but some semantic left) and anterograde amnesia (able to learn semantic info @ slower rate). His case lent support to the
episodic memory theory
of hippocampal memory (since he still had encoding/retrieval of semantic memories), along with the presence of
A type of amnesia in which a person has amnesia while growing up. In these cases, these kids have relatively normal working memory, but lowered episodic memory. Surprisingly, they had average-low average IQ, meaning their semantic memory was likely not as impaired as episodic memory. These individuals provide evidence for a distinction between semantic/episodic memory.
Somewhat the reverse of AD (where episodic is lost due to MTL, but some semantic remains); due to left anterior temporal lobe atrophy. This is marked by loss of both linguistic and non-linguistic semantic knowledge (they can't speak), but non-verbal episodic memory is spared.
- Encoding (transfer sensory data into a mental representation)
- Storage (keep encoded information)
- Retrieval (pull out information stored in memory)
All 3 steps must work for memory to work.
What are the three component processes of memory?
Storage/retrieval because it's hard to tell why one failed rather than the other. Encoding is easier because it's a distinct moment in time. Usually, retrieval is the step at fault.
Which two steps of the component processes of memory are harder to separate out experimentally?
