How Your Brain Works: Cool Science About Evolution, Depression, and Feelings!

The biological approach in psychology explores brain structure, neurotransmitters, and evolutionary influences on human behavior and mental processes.

  • Evolutionary psychology and natural selection examples demonstrate how behaviors like altruism evolved to enhance survival
  • Neurotransmitters role in depression and schizophrenia is explored through various drug therapies targeting specific chemical messengers
  • Localisation of brain functions and cerebral cortex responsibilities are studied using advanced imaging techniques like PET scans
  • Research methods combine scientific approaches with brain imaging to understand biological bases of behavior
  • Drug therapies target specific neurotransmitter systems to treat mental health conditions

Drug Therapy Components and Mechanisms

Drug therapy addresses mental health conditions through three main categories: anti-psychotics, anti-depressants, and anti-anxiety medications. Each type targets specific neurotransmitter systems to alleviate symptoms.

Definition: Anti-psychotics work by blocking dopamine receptors, helping manage schizophrenia symptoms by regulating neurotransmitter activity.

Example: Prozac, an SSRI antidepressant, works by preventing serotonin breakdown, thereby increasing its availability in the brain.

Highlight: Beta-blockers reduce anxiety by blocking adrenaline receptors on heart cells, demonstrating the direct connection between biological processes and psychological symptoms.

The effectiveness of these treatments has been demonstrated through numerous controlled studies, though side effects and limitations must be considered.

Quote: "Although the drugs are extremely effective in treating disorders, they also come with many side effects like nausea, headache and insomnia."

Page 2: Drug Therapy Approaches

This section details the three main categories of psychoactive medications used to treat mental health conditions. Each type targets specific neurotransmitter systems to address different symptoms and disorders.

Definition: Anti-psychotics work by modulating dopamine activity to treat schizophrenia symptoms.

Example: Prozac, an SSRI antidepressant, works by preventing serotonin breakdown in the brain.

Highlight: Different drug classes target specific neurotransmitter systems: dopamine for psychosis, serotonin for depression, and GABA for anxiety.

Vocabulary: SSRI (Selective Serotonin Reuptake Inhibitor) is a common class of antidepressant medications.

Page 3: Raine's Research on Brain Activity

This section presents a significant research study examining brain activity differences between murderers and controls using PET scanning technology.

Definition: PET (Positron Emission Tomography) scanning reveals brain activity patterns by tracking glucose metabolism.

Example: The study found distinct patterns of brain activity in murderers, particularly in the prefrontal cortex and emotional centers.

Highlight: The research demonstrated significant differences in brain activity between murderers and matched controls, particularly in regions associated with emotion and impulse control.

Evolutionary and Neurological Foundations

The biological approach to psychology examines behavior through three key assumptions: evolutionary influences, brain localization, and neurotransmitter function. Darwin's theory of natural selection explains how beneficial behaviors persist through generations, with altruistic parenting being a prime example of adaptive behavior.

Definition: Environment of Evolutionary Adaptiveness (EEA) refers to the conditions under which specific behavioral traits evolved to enhance survival.

Example: Parents' instinctive protection of offspring represents an evolutionarily advantageous behavior that ensures gene transmission.

The brain demonstrates functional specialization across its regions, particularly in the cerebral cortex's four main lobes. Each area serves distinct purposes, from processing sensory information to managing higher cognitive functions.

Highlight: The cerebral cortex's specialized areas include Broca's and Wernicke's areas, crucial for language processing and comprehension.

Vocabulary: Neurons are specialized cells that form the nervous system's foundation, communicating through chemical messengers at synapses.
