Study Notes

Key Terms and Concepts in Neuroscience

Lesion: Tissue destruction in the brain which can occur naturally or be experimentally induced by scientists targeting specific areas.
Electroencephalogram (EEG): A method to measure brain electrical activity. Electrodes on the scalp amplify and record the brain waves as they change.
CT Scan: Utilizes multiple X-ray images taken from different angles, combined through computer technology to visualize brain structure and identify damage.
PET Scan: Visualizes brain activity by tracking the movement of radioactive glucose during mental tasks, revealing metabolic processes within various brain regions.
MRI Scan: Employs magnetic fields and radio waves to create detailed images of soft tissues, primarily used for visualizing brain and spinal structures.
fMRI Scan: Advanced imaging technique that shows brain blood flow and activity, allowing simultaneous assessment of brain structure and function.
Brainstem: Fundamental part of the brain responsible for vital life functions like breathing and heartbeat; it extends from the spinal cord into the skull.
Pons: Sits above the medulla and plays a key role in coordinating movements and ensuring communication between different brain areas.
Medulla: Critical for autonomic functions, its location at the base of the brainstem allows it to oversee vital processes like heartbeat and respiration.
Reticular Formation: A network of neurons in the brainstem essential for regulating arousal and consciousness; damage here may lead to a coma.
Thalamus: Functions as the brain's sensory relay station; sends sensory information (except for smell) to the appropriate areas in the cerebral cortex.
Cerebellum: Located at the back of the brain; coordinates voluntary movement, balance, and processes sensory input.
Limbic System: Emotionally significant part of the brain; includes structures such as the hippocampus, amygdala, and hypothalamus linked to emotional responses and drives.
Amygdala: Small, almond-shaped clusters in the limbic system associated with emotional processing, particularly fear and pleasure.
Hippocampus: Key structure for memory formation and retrieval; significantly involved in learning processes.
Hypothalamus: A vital regulatory center that manages bodily functions like hunger, thirst, temperature, and governs the endocrine system through the pituitary gland.
Cerebral Cortex: The outer layer of the brain involved in higher-order functions like thinking, decision-making, and sensory processing; often referred to as the brain's control center.
Glial Cells: Supportive cells in the nervous system that care for neurons, potentially aiding in learning and cognitive functions.
Frontal Lobes: The cerebral cortex section responsible for voluntary movement, complex cognitive tasks like planning, and regulation of behavior; positioned behind the forehead.
Parietal Lobes: Located at the top of the brain, these lobes process sensory information related to touch and spatial orientation.
