Active Regions

Definition

Active regions refer to the specific areas of the brain that are involved and engaged during a particular cognitive task or mental process.

Analogy

Think of active regions as the bustling city centers within our brains. Just like how certain neighborhoods in a city are vibrant and full of activity, active regions in our brains are buzzing with neural activity when we are engaged in tasks like memory recall.

Functional Magnetic Resonance Imaging (fMRI): This brain scanning technique uses magnetic fields to track changes in blood flow, allowing researchers to identify active regions of the brain during different mental processes.

Positron Emission Tomography (PET) Scan: A PET scan involves injecting a small amount of radioactive substance into the bloodstream, which then highlights areas with increased metabolic activity, providing information about active regions.

Electroencephalogram (EEG): An EEG measures electrical activity in the brain through electrodes placed on the scalp, providing real-time information about brain wave patterns and identifying active regions.
