Study Notes
Brain-Mind Connection
- Brain activity directly correlates with perceptions and emotions, emphasizing its role in shaping personal identity.
- Perception is a product of the brain rather than an external phenomenon.
- Mental and brain activities are intertwined; critical assessment of behavior explanations is essential.
Types of Biological Questions
- Physiological: Studies the relationship between behavior and brain physiology.
- Ontogenetic: Investigates how individual behaviors develop over time.
- Evolutionary: Explores the historical evolution of behavioral capacities.
- Functional: Examines the purpose and adaptive significance of behaviors.
Careers in Biological Psychology
- Career opportunities include research positions, medical fields, and counseling/psychotherapy practices.
The Use of Animal Research
- Why Study Animals?: Behaviors can be more easily researched in animals due to similar biological mechanisms; ethical constraints limit human experimentation.
- Ethical Considerations: Animal research poses ethical dilemmas due to potential distress, regulated to reduce harm while enabling vital studies.
Thought Questions for Reflection
- Consciousness: Questions the usefulness and unique advantages of consciousness.
- Behavior Evolution: Discusses the challenges posed by studying behavioral evolution without fossil evidence.
Understanding Neurons and Their Role in Behavior
- Neurons are critical to understanding behavior and cognition, with learning linked to the principle “cells that fire together, wire together.”
Key Concepts
- Neuronal Anatomy: Neurons have a complex structure including the soma, dendrites, axon, and presynaptic terminals; shapes vary by function.
- Energy Requirements: Neurons utilize glucose for energy; the brain accounts for 20% of oxygen and 25% of glucose consumption despite being 2% of body weight.
- Thiamine and Neuronal Function: Vitamin B1 (thiamine) is vital for glucose metabolism; deficiencies can cause serious issues like Korsakoff’s syndrome.
- Blood-Brain Barrier: Protects the brain by allowing only specific substances to enter; glucose transport facilitated by active proteins.
Key Points to Remember
- Glial cells support neuronal function and enhance brain activity.
- Behavior arises from the interplay of neuron communication rather than isolated neuronal actions.
Key Terms
- Neurons: Cells responsible for transmitting information.
- Glia: Supportive cells in the nervous system.
- Blood-Brain Barrier: A selective barrier regulating substance entry into the brain.
- Active Transport: Movement of substances against their concentration gradient across membranes.
Thought Question
- Consider the effects of heroin and morphine; investigate how their similarities influence their interactions with the blood-brain barrier and the speed of their effects.
