3 Neural circuits of learning and memory Flashcards
What are the 4 step of memory formation
(1) Encoding
(2) Storage
(3) Consolidation
(4) Retrieval
Which brain region is involved in the sensory memory?
Neocortex
Which brain region is involved in the working memory?
Frontal lobe
What are the 2 types of short term memory?
sensory memory and working memory
What are the 2 main types of long term memory?
Declarative (Explicit) memory and Non-declarative (Implicit) memory
What are the 2 types of declarative (explicit) memory?
Semantic memory and episodic memory
What are the 4 types of Non-declarative (implicit) memory?
priming, procedural, associative learning (conditioning), and non-associative learning (habituation, sensitization)
Which brain region is involved in the declarative (explicit) memory?
Medial temporal lobe, Hippocampus, Thalamus
Which brain region is involved in priming?
Neocortex
Which brain region is involved in procedural memory?
Striatum, motor cortex, cerebellum
Which brain region is involved in associative learning (conditioning)?
Amygdala, cerebellum
Which brain region is involved in non-associative learning (habituation, sensitization)?
reflex pathways
Which takes larger to learn, implicit memory or explicit memory?
Implicit memory
Which is more robust and may last for all our life even in the absence of further practice, implicit or explicit memory?
Implicit memory
What is memory engram?
The physical representation or location, aka memory trace
What are the key points of Donald Hebb’s cell assembly hypothesis?
(1) External events are represented by cortical cells
(2) Cells reciprocally interconnected
(3) Short-term memory is actively reverberated through the connections of cell assembly
Memory consolidation is distinguished into which two specific processes?
(1) Synaptic consolidation
(2) Systems consolidation
Implicit memory is heterogeneous collection of memory or homogeneous collection of memory?
Heterogeneous
Lesion of hippocampus lead to which type of amnesia?
Anterograde amnesia
Where are the grid cells located?
In the entorhinal cortex
Standard radial arm maze learning is implicit learning or explicit learning?
Explicit
Modified radial arm maze learning is implicit learning or explicit learning?
Implicit
Standard radial arm maze learning is associated with which brain region?
Hippocampus
Modified radial arm maze learning is associated with which brain region
striatum
