Chapter 11 Flashcards
What’s the different between anterograde and retrograde amnesia?
Anterograde- inability to remember inability to remember events that occur after injury
Retrograde- inability to remember events that occur before injury
What’s the difference between episodic and semantic memories?
Episodic- explicit memories for particular events
Semantic- explicit memories for general facts or info
What are the three major structures of the medial temporal lobe?
Hippocampus, amygdala, and Rhinal cortex
What part of the brain is consistently damaged in individuals with korsakoff’s disease?
Mediodorsal nuclei of the thalamus
Which area of the brain has been associated with memory for spatial location?
Hippocampus
What type of information is stored in the inferontemporal cortex?
Visual input
What type of information is stored in the amygdala?
Emotional significance of experiences
What type of information is stored in the cerebellum?
Working memory, temporal order of events.
What type of information is stored in the striatum?
Consistent relationships between stimuli and responses
What is long-term potentiation (LTP)
Facilitation of synaptic transmission following high-frequency electrical stimulation applied to presynaptic neurons
LTP research has focused on which part of the brain
Hippocampus. (We study it in rats)
What is the critical factor in LTP?
Co-occurrence of firing in the presynaptic and postsynaptic cells is necessary for learning and memory
(Does not fire if presynaptic cell fires and postsynaptic does not fire, does not fire if presynaptic cell does not fire and the postsynaptic cell does)
What neurotransmitter is associated with NMDA receptors? Is this neurotransmitter excitatory or inhibitory?
Glutamate. Excitatory.
Describe the type of information stored in the cerebellum
Learned sensorimotor skills
