mechanism of memory formation
Term | Definition |
---|---|
Alzheimer's disease | A disease which progressively destroys neurons in the brain, causing memory loss. |
Amnesia | Memory loss. |
Amygdala | 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 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. |
Dementia | A neurological disorder affecting higher mental functions, and may be caused by disease or brain damage. |
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 consolidation of explicit (declarative) memories and acts to transfer these to other parts of the brain for storage as long-term memory. |
Neuron | Nerve cells, responsible for communication within the body. |
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. |
