Neuroscience Overview Quiz

Study Notes

Neuroscience

Definition: Study of the nervous system, including the brain's structure and function.
Key Concepts:
- Neurons: Basic building blocks of the brain; transmit information through electrical and chemical signals.
- Neurotransmitters: Chemicals that facilitate communication between neurons (e.g., dopamine, serotonin).
- Brain Structures:
  - Cerebral Cortex: Involved in higher functions such as thought, language, and consciousness.
  - Limbic System: Emotion and memory regulation; includes the amygdala and hippocampus.
  - Brainstem: Controls basic life functions like breathing and heartbeat.
Techniques:
- fMRI (Functional Magnetic Resonance Imaging): Measures brain activity by detecting changes in blood flow.
- EEG (Electroencephalography): Records electrical activity of the brain; used in sleep studies and epilepsy diagnosis.
Applications:
- Understanding neurological disorders (e.g., Alzheimer's, Parkinson's).
- Development of treatments through neuropharmacology.

Cognitive Psychology

Definition: Study of mental processes including perception, memory, thought, and problem-solving.
Key Concepts:
- Information Processing: The brain as a processor of information, similar to a computer.
- Memory Types:
  - Short-term Memory: Temporary storage for information; limited capacity.
  - Long-term Memory: Permanent storage; can be explicit (declarative) or implicit (non-declarative).
- Cognitive Development: Understanding how thinking evolves over a lifespan; heavily influenced by Jean Piaget's stages.
Processes:
- Perception: The interpretation of sensory information; involves attention and recognition.
- Decision Making: Involves evaluating information and choosing a course of action.
- Problem Solving: Strategies for finding solutions, including algorithms and heuristics.
Applications:
- Improvement of learning methods through understanding memory.
- Development of cognitive-behavioral therapies for mental health issues.

Neuroscience

Study focused on the nervous system, encompassing brain structure and function.
Neurons are the fundamental units of the brain, transmitting information via electrical and chemical signals.
Neurotransmitters facilitate neuron communication; notable examples include dopamine (associated with pleasure) and serotonin (linked to mood regulation).

Brain Structures

The Cerebral Cortex is responsible for higher-order functions such as thinking, language, and awareness.
The Limbic System, containing the amygdala and hippocampus, manages emotional responses and memory processes.
The Brainstem oversees essential life-sustaining functions, including respiration and heartbeat regulation.

Techniques

fMRI (Functional Magnetic Resonance Imaging) detects brain activity by monitoring changes in blood flow.
EEG (Electroencephalography) captures electrical brain activity, widely used in research on sleep patterns and epilepsy diagnosis.

Applications

Neuroscience aids in understanding neurological disorders like Alzheimer’s and Parkinson’s disease.
Neuropharmacology contributes to developing innovative treatments for various brain-related conditions.

Cognitive Psychology

Focuses on understanding mental processes such as perception, memory, thought, and problem-solving.
The Information Processing model compares brain function to computer data management and analysis.

Memory Types

Short-term Memory serves as temporary information storage with limited capacity.
Long-term Memory provides permanent storage, categorized into explicit (declarative) and implicit (non-declarative) memory.

Cognitive Development

Jean Piaget's theories provide insight into cognitive development, illustrating that thinking evolves through distinct stages over a person’s lifespan.

Processes

Perception involves interpreting sensory data, shaped by attention and recognition mechanisms.
Decision Making entails assessing information and determining actions based on evaluations.
Problem Solving employs strategies, including algorithms (step-by-step procedures) and heuristics (mental shortcuts), to reach solutions.

Applications

Enhancements in learning methodologies stem from improved understanding of memory dynamics.
Development of cognitive-behavioral therapies addresses mental health challenges, improving therapeutic outcomes.
