Study Notes
Biopsychology and Neuroscience
- Biopsychology examines the interplay between biology, behavior, and mental processes.
- Fields involved include biology, neurology, chemistry, computer science, and cognitive psychology.
- Brain activity can translate imagined handwriting into text using advanced technology.
Nervous System
- Composed of a complex network of neurons, responsible for information processing and communication throughout the body.
- Neurons transmit signals via electrical and chemical means, with neurotransmitters relaying messages across synapses.
Neurotransmitters
- Acetylcholine (ACh): Involved in arousal, attention, memory, and muscle contractions.
- Norepinephrine (NE): Impacts arousal and mood.
- Dopamine (DA): Key to movement control and pleasure sensations.
- Serotonin (5-HT): Regulates sleep, mood, anxiety, and appetite.
- Gamma-aminobutyric acid (GABA): Major inhibitory neurotransmitter, crucial for sleep and reducing movement.
- Glutamate: Essential for learning and memory formation, promotes nervous system development.
- Endorphins: Inhibitory regulators involved in pain relief.
Agonists and Antagonists
- Agonists: Mimic or enhance neurotransmitter effects, affecting cell activity.
- Antagonists: Block or reduce responses to neurotransmitters.
Spinal Cord Reflex
- Sensory neurons: Convey messages from sense receptors to the central nervous system (CNS).
- Motor neurons: Transmit messages from CNS to muscles and glands.
- Interneurons: Facilitate communication between sensory and motor neurons.
Autonomic Nervous System
- Regulates involuntary body functions, divided into:
- "Rest and digest" (Parasympathetic)
- "Fight or flight" (Sympathetic)
Endocrine System
- Comprises glands secreting hormones directly into the bloodstream.
- Influences emotions, behavior, and bodily functions.
Brain Structures and Functions
- Hindbrain: Includes brain stem and cerebellum, vital for basic life functions.
- Limbic System: Associated with emotions and memory.
- Cerebral Cortex: High-level cognitive functions; organized into lobes.
Hemispheric Lateralization
- Each hemisphere specializes in different functions:
- Left Hemisphere: Dominant in language processing and logical thought.
- Right Hemisphere: Involved in nonverbal activities and visual-spatial processing.
- Split-brain studies reveal how severing the corpus callosum affects communication between hemispheres.
Neuroplasticity and Changes in Synaptic Connections
- Long-term Potentiation: Strengthens synaptic connections through repeated stimulation.
- Neurogenesis: Formation of new neurons, essential for learning.
- Pruning: Elimination of unused neuron connections to optimize brain efficiency.
Methods to Study the Living Brain
- Brain Lesion Studies: Investigate brain function by examining injured regions, exemplified by Phineas Gage.
- Brain Stimulation: Uses electric currents to elicit neuronal responses, can be invasive (TMS) or non-invasive.
-
Imaging Techniques:
- CT Scan: Provides structural images using X-rays.
- MRI: Offers detailed structural imaging using magnetic and radiofrequency energy.
- fMRI: Measures brain activity by detecting blood oxygen level changes.
- PET Scan: Assesses brain function with radioactive glucose.
- EEG: Records electrical activity of neurons via electrodes on the scalp.
- MEG: Measures magnetic fields from neuronal activity.
- fNIRS: Monitors brain activity through changes in blood oxygen levels.
Additional Findings
- Research using EEG indicates that taking notes by hand may enhance retention and understanding compared to typing.
