The Anatomy of Memory and Emotion Flashcards
(37 cards)
Explicit/Declarative Memory:
Memories, which can be consciously recalled as facts and events
Implicit Memory:
acquisition of motor and cognitive skills; which manifest across a wider range of situations
Memory Flow Chart:
Episodic Memory:
- makes the acquisition and retrieval
of information about specific
personal experiences that occur at a
specific time and place
Working Episodic Memory:
- supports the temporary storage and
maintenance of internal
representations
Long term episodic:
- more permanent form of memory,
permitting the acquisition and
retrieval of information after long
periods
Semantic Memory:
- a form of explicit/declarative
memory - refers to individual general
knowledge (facts)
(when examining test vocab/amnesiac patients fail to acquire new vocab)
Semantic Memory Examination:
- Word Association Test
1) Phonological Fluency = subject is
asked to recall as many words as
possible starting with a letter (F,A,S)
2) Categorical Fluency = subjects
required to produce as many
responses to conceptual categories
as they can in a minute
(animals/fruit)

Procedural Memory:
- a form of implicit memory referring
to the acquisition of motor and
cognitive skills - three stages: cognitive, association
and autonomous
Perceptual Learning:
- form of procedural implicit learning
- indicates that the ability of sensory
systems to respond to stimuli is
improved through experience
Classical Conditioning:
- learning process
- occurs when two stimuli are
repeatedly paired - response which initially is elicited by
the second stimulus is eventually
elicited by the first alone
Hippocampus functions (3):
- episodic memory: what you had for
breakfast - encoding and recollection of long-
term memories: early life events,
info, experiences - spatial processing and navigation:
place cells
Hippocampus: Anatomy:
- locations
- structures and cells
- medial temporal lobe and bilateral
- Cornu Ammonis: CA1-4, Dentate
Gurus, Subiculum - CA1-4 are densely packed with
pyramidal cells = hippocampus
proper - DG = granular cells, episodic memory
- Subiculum = pyramidal cells,
plasticity
Hippocampus:
Hippocampus: Inputs:
- multiple areas of the cerebral cortex
(prefrontal, cingulate, temporal etc) - these project via the entorhinal
cortex into the hippocampus via the
subiculum
Hippocampus: Outputs:
- via the subiculum to
- prefrontal cortex, amygdala,
mamillary bodies etc - **fornix is a major output pathway
Hippocampus Inpur and Outputs:
Hippocampus: Connections:
Damage to the hippocampus can cause (3):
- amnesia = memory loss; anterograde
- difficulties in spatial navigation
- regulatory problems: sleep, impulse
control
What is shown below? Function?
- working memory, requires effort
Dorsolateral prefrontal complex
Parahippocampal gyrus:
- recognition memory
Categorical memory, word recognition, objects, people and faces are found in which cortices
temporal cortices
Association cortices are involved with
semantic memory
