Memory Lecture Flashcards
The three components of memory are _
Encoding
Storage
Retreival
Explicit memory (vs. implicit) is _. It is also known as _
Concious retreival of information
Declarative memory
Semantic memory (vs. episodic) is_
Memory of general declarative information (e.g. facts)
Episodic memory (vs. semantic) is _
Memory of event with persona connection
Short term memory refers to _
Memory that is held in consciousness for less than 40 seconds
Long term memory refers to _
Memory that is retreived after it has left conciousness (more than 1 minute)
Anterograde amnesia is _
Forgetting things “after” event
Retrograde amnesia is _
Forgetting things “before” event
Implicit memory _
Facilitation of current behaviors based on past experience
Proceedural memory
Motor learning involving incremental acquisiting of skills, resistant to forgetting
Priming memory is
Short lived enhancement based on recent exposure
Attention is dissociated from memory. Its definition is _
Orientation to and action upon selected sensory percepts
On a molecular level, memory involves (2)
Alterations in synaptic firing
Alterations in cellular morphology
The 2 major structures involved with anterograde long term memory are _
Thalamus
Hippocampus
Following medial temporal lobe lesion, what types of memory are affected?
Long term episodic memory
- complete loss of anterograde, graded of retrograde memory
Medial temporal lobe lesions are seen with what disease?
HSE - Herpes simplex encephalitis
Damage to the left anterior thalamus leads to _
Moderate anterograde verbal amnesia
Damage to the basal forebrain results in _
Deficits in time-tagging of information. Patients tend to fill in the blanks
Executive function deficit
Lesions to hippocampus result in retrograde amnesia. What is the effect of time?
More severe amnesia with memories closer to event. Earlier memories preserved
Semantic dementia is associate with what type of damage?
Widespread bilateral damage to the posterior cortical regions
Working memory is affect/not affected in temporal lobe amnesia
Not affected
Implicit memory (learned by repeated exposure) is accessible to the consciousness. True or false
False
Proceedural memory, a type of implicit memory is preserved in alzheimers disease. true or false
True
Frontal dysexecutive amnesia is an amnesia syndrome. It is characterized as _. The lesion would be found where?
Patient forgets to remember
Dorsolateral prefrontal cortex
Acute amnesic syndrome is can be caused by _ (4)
Stroke
Traumatic brain injury
Anoxia
HSE
Signs of amnesia due to anoxia can be seen via imaging , true or false
True
Transient global amnesia is _. It is caused by _
Sudden onset anterograde and retrograde amnesia
Caused by emotional events, stress, physical activity
In alzheimers patients, neural fibrilary tangles accumulate in what structure?
Hippocampus
HSE lesions in the right medial temporal lobe lead to _
HSE lesions in the left medial temporal lobe lead to _
Visual impairments
Verbal learning impairments
