ch 12 Flashcards
Henry Molaison’s (HM’s) life would forever be changed in 1953, when doctors removed his___in an attempt to treat his seizures.
temporal lobes
As a result of his surgery, what deficits did HM show?
difficulty learning and retaining new info
___amnesia is an inability to remember events that occurred PRIOR to the impairment. ___amnesia is an impairment in forming NEW memories.
retrograde; anterograde
research suggests that HM developed amnesia because the surgery destroyed his___and the surrounding area.
hippocampus,
when psychologists talk about memory consolidation, they are referring to
the process in which the brain forms a more or less permanent physical representation of a memory
Water maze research with rats demonstrated that blocking glutamate activity in the hippocampus…
impaired recall
indicates that hippocampus has role in retrieval as well as consolidation
Which of the following statements about the permanent storage of memories in the brain is true?
?
When a presynaptic neuron is active at the same time that a postsynaptic neuron fires…
the synapse between them will be strengthened
Your memory for the events that have occurred over the course of the semester would be considered…
declarative memory
The most common cause of dementia is___, A disorder that involves progressive brain deterioration, impaired memory and other cognitive impairments, and changes in emotional and behavioral functioning
Alzheimer’s
a simple phrase that best summarizes the Hebb rule is…
?
Long-term potentiation (LTP) involves:
Definition: increase in synaptic strength resulting from the simultaneous activation of presynaptic neurons and postsynaptic neurons
involves: cascade of events at synapse. NT involved is glutamate
After LTP occurs, changes in gene activation and proteins synthesis occur within neurons. This leads to many physical changes in the neurons that are associated with memory and learning. Which of the following is one of these changes?
generation of new neurons in hippocampus
Why does sleep appear to be important for learning and memory?
because the hippocampus transfers information to the cortex during times when hippocampus is less occupied. During sleep neurons in hippocampus and cortical areas repeat the pattern of firing that occurred during learning
Research demonstrates that after a memory has been recalled, it is vulnerable to being altered. For a long time we have known that memories change over time. However, researchers now believe that this occurs because…
extinction, forgetting, reconsolidating
