Study Notes
Brain Vocabulary Overview
- Ablation: Refers to the surgical removal of brain tissue, often to treat various neurological disorders.
- Axial Plane: Also known as the horizontal plane, crucial for understanding brain imaging.
- Basal Ganglia: Subcortical structures in the cerebral hemispheres that play a critical role in the regulation of voluntary movements.
- Brain Stem: The core part of the brain consisting of the medulla, pons, midbrain, and diencephalon, vital for basic life functions.
- Callosotomy: A surgical procedure involving the severing of the corpus callosum, primarily used to manage severe epilepsy.
Research and Imaging Techniques
- Case Study: In-depth examination of patients with natural brain lesions providing insights into brain function.
- Cerebellum: Located at the back of the brain, also called the "small brain," involved in coordination and balance.
- Cerebral Cortex: The outer layer of gray matter in the cerebrum noted for its convoluted structure.
- Cerebral Hemispheres: Include the cerebral cortex, white matter, and subcortical structures, essential for complex functions.
- Cerebrum: Typically refers to the cerebral cortex and its underlying white matter, sometimes inclusive of subcortical structures.
Hemispheric Functions and Neuroimaging
- Contralateral: Indicates how each hemisphere of the brain processes information from and controls the opposite side of the body.
- Converging Evidence: Refers to findings corroborated by multiple independent studies utilizing various methodologies.
- Coronal Plane: A vertical slice of the brain from head to foot, likened to slices of bread.
- Diffuse Optical Imaging (DOI): A neuroimaging method that assesses brain activity through light changes measured on the skull.
- Electroencephalography (EEG): A technique that records electrical activity in the brain using multiple scalp electrodes.
Brain Regions and Their Functions
- Frontal Lobe: Positioned at the front of the cerebrum, responsible for motor functions, planning, language, judgment, and decision-making.
- Functional Magnetic Resonance Imaging (fMRI): A technique that detects brain activity through blood oxygen level changes, important for functional mapping.
- Gray Matter: Composed of neuronal cell bodies, primarily found in the outer regions of the brain.
- Gyri and Sulci: Gyri are the folds between sulci (the grooves), collectively shaping the cerebral cortex.
Anatomical Plans and Brain Processes
- Horizontal Plane: A slice running parallel to the ground, dividing the brain into top and bottom sections, akin to a hamburger bun.
- Lateralized Functions: Specific brain functions predominantly located in one hemisphere; for example, language is typically associated with the left hemisphere.
- Lesion: A region of the brain that has experienced damage due to injury or disease, providing crucial information for research.
- Limbic System: Comprising of the amygdala and hippocampus, key in emotional regulation and memory processes.
Neurotransmission and Brain Imaging Characteristics
- Metabolite: Essential substances required for life maintenance within an organism.
- Motor Cortex: The area in the frontal lobe that governs voluntary movements and represents body functions contralaterally.
- Myelin: Fatty substance formed by glial cells that insulates neuronal axons, crucial for efficient electrical impulse conduction.
- Nomenclature: The system of names used in the study of brain structure and function to avoid confusion.
Functional Areas of the Cerebrum
- Occipital Lobe: The region located at the back of the cerebrum that is primarily responsible for vision.

- Sagittal Plane: A vertical slice that divides the brain into left and right hemispheres, resembling a baked potato cut lengthwise.
- Somatosensory Cortex: Located in the parietal lobe, responsible for processing bodily sensations with contralateral representation.
- Spatial Resolution: Describes the image's detail level; high spatial resolution allows the imaging of small brain structures.
- Split-brain Patient: Someone who has undergone a callosotomy, providing insights into lateralization of brain function.
Neurostimulation Techniques
- Transcranial Direct Current Stimulation (tDCS): A method that applies mild electrical currents to specific brain areas to modulate activity.
- Transcranial Magnetic Stimulation (TMS): Involves applying a magnetic pulse to the head to induce electrical currents, influencing neurological activity.
- Transverse Plane: Equivalent to the horizontal plane, providing another perspective for brain sectioning.
- Visual Hemifield: Each hemisphere's control over corresponding halves of visual space, with the right hemisphere processing the left hemifield and vice versa.
White Matter
- White Matter: Inner areas of the cerebrum consisting of axons insulated by myelin, critical for efficient communication between brain regions.
