|
Medial temporal region
|
Forms, organizes, consolidates, and retrieves memories
|
|
|
Cortical areas role in the formation of memories
|
-Important for long-term storage of knowledge about facts and events and for how this knowledge is used in everyday situations.
-Cortical areas in the cerebral cortex play a distinct role in complex aspects of perception, movement, emotion, and cognition. |
|
|
Declarative memory
|
Our ability to learn and consciously remember everyday facts and events.
|
|
|
Working memory
|
A transient form of declarative memory in which information from new experiences initially enters.
|
|
|
Semantic memory
|
A form of declarative knowledge that includes general facts and data.
|
|
|
Episodic memory
|
Memory of specific personal experiences that happened at a particular place and time.
-The temporal lobe areas serve a critical role in the initial processing and storage of these memories. |
|
|
Role of the parahippocampal region in the formation of memories
|
Processes “what,” “where,” and “when,” information about specific events.
|
|
|
Nondeclarative knowledge
|
The knowledge of how to do
something that is expressed in skilled behavior and learned habits. -It requires processing by the basal ganglia and cerebellum, and it occurs prominently in the hippocampus, as well as in the cerebral cortex and other brain areas. |
|
|
Long-term potentiation (LTP)
|
A long lasting increase in the strength of a synaptic response following stimulation that occurs prominently in the hippocampus. LTP occurs through changes in the strength of synapses at contacts involving N-methyl-d-aspartate (NMDA) receptors
|
|
|
Molecular reactions that play a role in the stabilization of the changes in synaptic function that occur in LTP
|
-entry of calcium ions into the synapse which activates the cyclic adenosine monophosphate molecule (cAMP)
-cAMP activates enzymes which increase the number of synaptic receptors, making the synapse more sensitive to neurotransmitters. |
|
|
role of cAMP
|
activates another molecule, called cAMP-response element-binding protein (CREB).
-CREB operates with the nucleus of the neuron to activate a series of genes, many of which direct protein synthesis, and increase the neuron's responsiveness to stimulation. |
