CT Scan (Computed Tomography)

A computer-controlled x-ray that provides a clear picture of brain structure.

PET Scan (Positron Emission Tomography)

A method that uses radioactive sugar to visualize active brain areas.

MRI (Magnetic Resonance Imaging)

A technique that uses magnetic fields and radio waves to create detailed images of brain structure.

fMRI (Functional MRI)

A method that measures and tracks changes in brain activity over time.

NIRS (Near Infrared Spectroscopy)

A newer method that uses infrared light to track blood oxygen levels in the brain.

Hindbrain

The most primitive part of the brain responsible for basic life functions.

Limbic System

A set of brain structures involved in learning, emotion, memory, and motivation.

Cerebral Cortex

The outer wrinkled part of the brain responsible for higher thought processes, sensory interpretation, and decision-making.

Broca's Area

Association Areas of the Brain

Regions that integrate information from different brain areas and support higher mental functions.

Neuroplasticity

The brain's ability to change and adapt through experience.

Autonomic Nervous System

Part of the nervous system that regulates involuntary body functions, divided into sympathetic and parasympathetic divisions.

Reflex Arc

A neural pathway that controls reflex actions, involving sensory neurons, interneurons, and motor neurons.
