    Study Notes

    Understanding the Connection Between Biology and Psychology

    • Psychologists integrate biological understanding with psychological processes, highlighting the brain's role in shaping thoughts and emotions.
    • Ancient beliefs placed the mind in the heart (Aristotle) versus the brain (Hippocrates), which has been largely corrected by modern science.
    • The study of phrenology, proposed by Franz Gall, suggested that bumps on the skull correlate to mental abilities, though later disproven, it introduced ideas about brain function localization.

    Advances in Biological Psychology

    • Biological psychologists utilize modern technologies to explore relationships between genetics, neural activity, and psychological phenomena.
    • Key discoveries reveal that experiences wire the brain and that discrete brain systems handle specific functions, integral to constructing perceptions and memories.
    • The concept of the biopsychosocial model emphasizes understanding behavior by examining interactions among biological, psychological, and social systems.

    Neurons and Neural Structures

    • Neurons are the basic building blocks of the nervous system, consisting of a cell body, dendrites (input), and axons (output).
    • Neurons communicate through action potentials, which are brief electrical charges traveling down axons at varying speeds.

    Neural Communication Mechanics

    • The synapse, a junction between neurons, plays a critical role in neural communication.
    • Action potentials trigger neurotransmitter release, which cross the synaptic gap to bind to receptors on receiving neurons, influencing their firing.

    Neurotransmitters and Their Functions

    • Numerous neurotransmitters affect behaviors and emotions, with systems that can enhance or inhibit responses based on receptor types.
    • Reuptake mechanisms recycle neurotransmitters, with certain medications (e.g., SSRIs) designed to affect this process to treat conditions like depression.

    Overall Neural Dynamics

    • Neural responses are all-or-none; a strong stimulus can increase firing rate but doesn't influence the action potential's strength.
    • Neurons operate as complex decision-making devices, influenced by signals from numerous other neurons, engaging in an intricate electrochemical communication process.### Neurotransmitters and Their Functions
    • Acetylcholine (ACh) is vital for muscle action, learning, and memory.
    • Dopamine influences movement, learning, attention, and emotion; an imbalance can lead to schizophrenia (oversupply) or Parkinson's disease (undersupply).
    • Serotonin affects mood, hunger, sleep, and arousal; drugs that increase serotonin levels are often used to combat depression.
    • Norepinephrine regulates alertness and arousal; its levels can impact mood.
    • GABA is a primary inhibitory neurotransmitter, helping to prevent excessive neuronal activity.
    • Glutamate serves as the major excitatory neurotransmitter and plays a crucial role in memory. Overactivity can lead to migraines or seizures.
    • Endorphins act as natural painkillers and mood enhancers; excessive opiate use can deplete natural endorphin levels.

    Impact of Drugs on Neurotransmission

    • Agonists are molecules that enhance neurotransmitter activity; they may mimic neurotransmitters or block their reuptake.
    • Antagonists inhibit neurotransmitter action by blocking receptor sites or preventing neurotransmitter release.
    • Examples: Curare blocks ACh action causing paralysis, while morphine mimics endorphins to alleviate pain and elevate mood.

    Nervous System Overview

    • The central nervous system (CNS) comprises the brain and spinal cord, acting as the command center for processing information.
    • The peripheral nervous system (PNS) connects the CNS to the body’s sensory receptors, muscles, and glands; it consists of sensory (afferent) and motor (efferent) neurons.

    Neurons

    • Sensory neurons transmit information from body tissues and sensory receptors to the CNS.
    • Motor neurons carry instructions from the CNS to muscles and glands.
    • Interneurons communicate internally within the CNS and process signals between sensory inputs and motor outputs.

    Peripheral Nervous System Components

    • The somatic nervous system enables voluntary control over skeletal muscles.
    • The autonomic nervous system (ANS) regulates involuntary actions, controlling glands and internal organ muscles, and is split into sympathetic (arousing) and parasympathetic (calming) systems.
    • Sympathetic responses include increased heart rate and blood pressure, while parasympathetic responses promote relaxation and energy conservation.

    Neurotransmitter Pathways and Their Effects

    • Disturbances in neurotransmitter pathways can lead to various disorders, emphasizing the interconnectedness of neurotransmission and behavior.
    • Natural neurotransmitter levels are critical; artificial alterations through drugs can disrupt this balance, often leading to dependence or withdrawal symptoms.

    • Neurons cluster for efficient communication, connecting in layers to facilitate quick transmission of information.
    • Learning involves strengthening connections between neurons; "neurons that fire together wire together."
    • The spinal cord serves as a two-way information highway between the brain and peripheral nervous system (PNS).
    • Reflex responses, like the knee-jerk reaction, involve a simple neural pathway of sensory and motor neurons, sometimes using interneurons.

    Reflexes and Sensory Processing

    • Reflex arcs operate independently of brain involvement, allowing quick responses to stimuli.
    • An example includes touching a flame, where the sensory neurons activate motor neurons to withdraw the hand instantly.
    • Information must reach the brain for sensations like pain or pleasure to be felt.

    Endocrine System Functions

    • The endocrine system includes glands that release hormones into the bloodstream, influencing various bodily functions and emotions.
    • Hormones travel slower than neural signals, akin to an old-fashioned letter compared to a text message.
    • The pituitary gland, controlled by the hypothalamus, is considered the master gland, influencing other endocrine glands and functions.

    Connection Between Nervous and Endocrine Systems

    • Both systems utilize chemical messengers but differ in speed and duration of effects.
    • The adrenal glands release hormones during stress, which prepare the body for the fight-or-flight response.
    • Feedback loops exist between the nervous system and endocrine system, such as stress triggering hormone release that affects brain activity.

    Neuron Types and Nervous System Division

    • The central nervous system (CNS) comprises the brain and spinal cord, acting as the decision maker.
    • The PNS connects the CNS to the body; it includes:
      • Somatic nervous system for voluntary muscle control.
