Chapter 11 Flashcards
Describe a Semantic memory
Explicit memories for facts and info
Describe the difference between anterograde and retrograde amnesia
Anterograde Amnesia: Inability to remember events that occur after injury
Retrograde Amnesia: Inability to remember events that occurs before injury
What are three major structures of the medial temporal lobe
Amygdala
Hippocampus
Rhinal Cortex
Describe an Episodic Memory
Explicit memories for events and experiences
What area 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
Describe the type of information that is currently thought to be stored by the inferotemporal cortex
Visual input
Describe the type of information that is currently thought to be stored in the amygdala
Emotional significance of experiences
Describe the type of information that is currently thought to be stored in the cerebellum
Learned sensorimotor skills
Describe the type of information that is currently thought to be stored in the striatum
Consistent relationships between stimuli and responses
What is long term potentiation (LTP)? LTP research has focused on which part of the brain?
- Facilitation of synaptic transmission following high frequency electrical stimulation of presynaptic neurons
- Studied in rat hippocampus most frequently
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
