    Study Notes

    Brain Overview

    • The brain is the central data center of the body, controlling thoughts, feelings, and behaviors.
    • Located in the cranial cavity, it consists of three main parts: cerebrum, cerebellum, and brainstem.
    • The cerebral cortex is the largest part of the brain, associated with higher-level functions including sensory interpretation, speech, reasoning, and emotional processing.

    Cerebral Hemispheres

    • The cerebrum has two hemispheres, right and left, joined by the corpus callosum for inter-hemispheric communication.
    • Each hemisphere controls the opposite side of the body due to contralateral control.
    • The left hemisphere is dominant for language, analytical thought, and motor control of the right side.
    • The right hemisphere excels in creativity, spatial abilities, and interpreting non-verbal cues and emotions.

    Language and Aphasia

    • Broca's area (left frontal lobe) is critical for speech production; damage leads to Broca's aphasia, characterized by difficulty speaking but preserved understanding.
    • Wernicke's area (left temporal lobe) is essential for language comprehension; damage leads to Wernicke's aphasia, resulting in fluent but nonsensical speech and poor comprehension.

    Brain Lobes

    • Each hemisphere is divided into four lobes: frontal, parietal, temporal, and occipital.
    • The frontal lobe (thinking, planning, memory) is at the front; the parietal lobe (touch processing) is in the middle; the occipital lobe (visual information) is at the back; the temporal lobe (hearing, language) is below the parietal lobe.

    Cerebellum

    • Located under the cerebrum, the cerebellum coordinates voluntary movements, maintains balance, and is involved in motor learning.
    • Damage to the cerebellum results in issues with coordination and stability, while alcohol consumption affects its functioning.

    Brainstem

    • The brainstem regulates vital life functions such as respiration, attention, and motor responses; it connects the cerebrum and cerebellum to the spinal cord.
    • Composed of the medulla, which controls heart rate and breathing, and the pons, which helps regulate movements and equilibrium.

    Limbic System

    • The limbic system, situated between the brainstem and the cerebral hemispheres, manages emotions, memory, and behavior.
    • Key components include:
      • Amygdala: governs fear and aggression responses, learning from threatening experiences.
      • Thalamus: processes and relays sensory information and helps regulate sleep.
      • Hypothalamus: regulates hunger, thirst, body temperature, and emotional responses through interactions with the endocrine system.
      • Hippocampus: essential for the formation of long-term memories; damage leads to an inability to create new memories.

    Cognitive Psychology

    • Cognitive psychologists study information acquisition, perception, processing, and memory storage.
    • Technologies like MRI help researchers visualize brain activity and investigate how structural differences affect health, personality, and cognitive function.

    Brain Overview

    • The brain controls thoughts, feelings, and behaviors; it acts as the body's primary data center, located in the cranial cavity.
    • Three main parts: cerebrum (higher-level functioning), cerebellum (coordination), brainstem (automatic functions).
    • The cerebral cortex is the outer layer of the cerebrum, responsible for advanced processes like touch, vision, hearing, speech, reasoning, emotions, and movement.

    Cerebral Hemispheres

    • The cerebrum has two hemispheres (right and left), connected by the corpus callosum.
    • Each hemisphere controls the opposite side of the body due to contralateral control.
    • Left hemisphere: Speech, comprehension, math, writing; dominant for hand use and language in roughly 92% of individuals.
    • Right hemisphere: Creativity, spatial ability, non-verbal communication; better at processing music and interpreting emotions and facial expressions.

    Analytical Functions and Aphasia

    • Left hemisphere handles complex language functions, analytical thought, and movement coordination.
    • Broca's area (left frontal lobe) is responsible for speech production; damage leads to Broca's aphasia.
    • Wernicke's area (left temporal lobe) is responsible for language comprehension; Wernicke's aphasia results in nonsensical speech and difficulty understanding.

    Brain Lobes

    • Each hemisphere is divided into four lobes: frontal (thinking, planning), parietal (touch processing), occipital (visual processing), and temporal (hearing, language).
    • The lobes are interconnected, working collaboratively for brain functions.

    Cerebellum Functions

    • Located under the cerebrum, it coordinates voluntary movements, posture, and balance.
    • Impaired cerebellum function leads to issues with walking and steadiness, especially exacerbated by alcohol consumption.
    • Contributes to emotional responses and sensory discrimination.

    Brainstem Responsibilities

    • The oldest brain region, governing life-sustaining activities such as breathing and heart rate.
    • Comprises the medulla (regulates vital functions) and the pons (regulates movement and equilibrium).
    • Houses the reticular formation, which processes incoming stimuli and affects attentiveness and sleep patterns.

    Limbic System

    • Positioned between the brainstem and cerebral hemispheres, essential for memory, emotions, and behavior.
    • Major structures: amygdala (fear and aggression regulation), thalamus (sensory processing), hypothalamus (regulation of hunger, thirst, and body temperature), and hippocampus (long-term memory storage).

    Cognitive Psychology and Brain Research

    • Cognitive psychologists study the acquisition and processing of information, language learning, and cognition-emotion interplay.
    • MRI technology allows researchers to visualize brain activity, enhancing understanding of brain function and its effects on personality and health.
