Study Notes
Role of the Hippocampus
- Essential for forming new memories and consolidating them into long-term storage.
- Involved in spatial navigation and contextual learning.
Moderate Stress and Memory
- Can temporarily enhance memory consolidation by promoting the release of neurotransmitters.
- Provides a heightened sense of alertness, which may improve focus on tasks.
Chronic Stress Effects on the Hippocampus
- Leads to structural changes such as reduced volume and neurogenesis.
- Impairs the ability to retrieve memories and learn new information.
Prefrontal Cortex and Corticosteroids
- When stimulated by corticosteroids, the amygdala releases stress hormones that can impair the prefrontal cortex.
- Resulting impairments affect decision-making, impulse control, and working memory.
Chronic Stress and Memory Acquisition
- Detrimentally affects the ability to acquire new memories and learn.
- Alters brain function, making it difficult to process and store new information.
Brain Area for Memory Consolidation
- The hippocampus is crucial for consolidating sensory experiences into lasting memories.
- Involves integrating and stabilizing information from various sensory modalities.
Process of Memory Formation
- Encoding is the term used for the process through which facts become memories.
- Involves initial perception and registration of new information for future retrieval.
Impact of Short-Term Stress on Memory
- Short-term stress negatively affects working memory and focuses attention on immediate tasks.
- Can lead to confusion and decreased problem-solving abilities.
Memory and Stress-Induced Blankness
- A "blank mind" during stress indicates an overload of cognitive processing.
- Hinders the ability to retrieve previously learned information.
State Disrupted by Stress
- Homeostasis refers to a state of calmness and tranquility.
- Stressors disrupt this balance, leading to heightened anxiety and cognitive impairment.
