CH:09 Mechanisms Of Memory Formation Flashcards
Amnesia
Memory loss
Alzheimer’s disease
a disease which progressively destroys neurons in the brain, causing memory loss
Amygdala
an almond-shaped structure, located in the medial temporal lobe of the brain. It is central in emotion, aggression and in implicit learning. It is vital in initiating and processing emotional responses and forming emotional memories
Anterograde amnesia
inability to encode and store new memories.
Axon
the part of a neuron along which the electrochemical nerve-impulse is transmitted
Consolidation
process in which the brain forms a permanent representation of memory
Dendrite
the tree-like element of a neuron that receives information from other neurons.
Hippocampus
finger-sized curved structure that
lies in the medial temporal lobes. It is responsible for the formation and consolidation of explicit (declarative) memories and acts to transfer these to other parts of the brain for storage as long-term memory. Also responsible for spatial memory and navigation
Neuron
nerve cells, responsible for communication within the body. They receive, process and transmit information.
Neurotransmitter
chemicals that help the communication across nerve synapses
Retrograde amnesia
inability to recall previously stored memories. This is a problem with retrieval
Soma
cell body of a neuron. Controls metabolism and maintenance of the cell
Synapse
the connection between two neurons. It is the junction between two neurons where the end of the presynaptic neuron comes into clost proximity with the receptor sites on the dendrites of a post synaptic neuron,
Synaptic transmission
The process of neurons communication with other neurons via a chemical process
Brain trauma
Refers to physiologically based amnesia. It is typically partial and selective amnesia. Can be caused by traumatic head injury, disease, seizure, malnutrition or chemical damage due to drugs
