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.
