Neuroscience
Term | Definition |
---|---|
Hippocampus | Crucial for the formation of new long-term declarative memories (episodic and semantic). It is heavily involved in spatial memory and contextual memory |
Amygdala | Involved in emotional learning, particularly fear conditioning. It modulates memory consolidation based on emotional significance |
Prefrontal Cortex | Responsible for decision-making, planning, and working memory. It plays a role in the organization and retrieval of information |
Cerebellum | Important for motor learning and classical conditioning of motor responses (e.g., eye-blink conditioning) |
Basal Ganglia | Involved in procedural learning, habit formation, and motor skills. |
Dopamine | Central to reward-based learning. Reinforces behaviors by increasing the likelihood of repeating actions that lead to rewards. |
Acetylcholine: | important for attention and encoding new memories |
Glutamate | Key in synaptic plasticity, involved in both LTP (long-term potentiation) and LTD (long-term depression). |
LTP (Long-Term Potentiation) | Strengthening of synaptic connections through repeated stimulation, associated with learning and memory formation. |
LTD (Long-Term Depression) | Weakening of synapses, which may contribute to forgetting or refining neural networks by eliminating unnecessary connections. |
Sleep in Memory | Sleep helps consolidate newly acquired memories, especially procedural and declarative memories. REM sleep is particularly involved in processing emotional and skill-related memories. |
