Unit 3: Mechanism Of Memory Formation Flashcards
What is Alzheimer’s disease?
Alzheimer’s disease is a disease which progressively destroys neurons in the brain, causing memory loss.
What is amnesia?
Amnesia is memory loss
What is the amygdala?
The amygdala is an almond shaped structure, located in the medial temporal lobe of the brain that is central in emotion, aggression and in implicit learning. It is vital in initiating and processing emotional responses and in forming emotional memories.
What is anterograde amnesia?
Anterograde amnesia is the inability to encode and store new memories
What is an axon?
Axon is the part of a neuron along which the electrochemical nerve impulse is transmitted
What is consolidation?
Consolidation is a process in which the brain forms a permanent representation of memory.
What is dementia?
Dementia is a neurological disorder affecting higher mental functions, and may be caused by disease or brain damage.
What are dendrites?
Dendrites are the tree-like element of a neuron that receives information from other neurons.
What is the hippocampus?
The hippocampus is a finger-sized curved structure that lies the the medial temporal lobes. It is responsible for consolidation of explicit (declarative) memories and acts to transfer these to other parts of the brain for storage as long-term memory.
What is a neuron?
Neurons are nerve cells, responsible for communication within the body.
What is a neurotransmitter?
Neurotransmitters are chemicals that help the communication across nerve synapses.
What is retrograde amnesia?
Retrograde amnesia is the inability to recall previously stored memories. This is a problem with retrieval.
What is a soma?
Soma is the cell body of a neuron. It controls metabolism and maintenance of the cell.
What is a synapse?
A synapse is the tiny gap between the dendrite of one neuron and the axon terminal of another, of which neurotransmitter are released into.
