Tool

Definition

In the context of measuring electrical activity in the brain, a tool refers to an instrument specifically designed to record and monitor electrical signals produced by neurons. These tools provide valuable information about brain function and are used in various research and clinical settings.

Electroencephalogram (EEG):

An EEG is a non-invasive tool used to measure electrical activity in the brain by placing electrodes on the scalp. It provides information about brainwave patterns associated with different states such as sleep or alertness.

Functional Magnetic Resonance Imaging (fMRI): fMRI is an imaging technique that measures changes in blood flow within the brain to track neural activity. It helps researchers identify which areas of the brain are active during specific tasks or experiences.

Single-Unit Recording: Single-unit recording involves inserting tiny electrodes directly into individual neurons to record their electrical activity. This technique provides highly detailed information about specific neuron firing patterns and responses.
