What is bioelectricity?

Bioelectricity is a concept in biology that involves the generation and use of electrical signals by living organisms, like an electric power grid. At the heart of bioelectricity are tiny, charged particles called ions, which are found inside cells. These ions can move in and out of cells through specialized channels in the cell membranes. When ions move, they create an electrical flow or current, like electricity flowing through wires.

This electrical activity is crucial for many biological processes. In the nervous system, for example, bioelectric signals travel along nerve cells to transmit information from the senses to the brain, enabling movement. In muscles, bioelectricity helps control muscle contractions, allowing walking, talking, and various other actions. Bioelectricity also plays a role in regulating heartbeats, triggering chemical reactions, and helping to heal wounds. Scientists are still discovering many of its secrets and exploring its potential in areas like regenerative medicine and bioengineering.Footnote 1

Why learn about bioelectricity?

A deep understanding of bioelectricity can be beneficial for a variety of careers, including:

  • Biomedical researcher: Works in academic institutions, pharmaceutical companies, or research organizations to investigate the role of bioelectricity in various biological processes.

  • Clinical electrophysiologist: Specializes in diagnosing and treating conditions related to the electrical activity of the heart or nervous system. They perform procedures like electrocardiograms (ECGs) and electromyography (EMG) to help diagnose and treat patients with heart arrhythmias, neuromuscular disorders, and more.

  • Biomedical engineer: Designs and develops medical devices and equipment, such as EEG (electroencephalogram) machines, pacemakers, and neurostimulation devices.

  • Neuroscientist: Studies the brain and nervous system, including the bioelectric signals that drive neural communication.

  • Clinical neurophysiologist: Diagnoses and treats neurological disorders, and assesses and manages conditions like epilepsy, nerve injuries, and neuromuscular disorders.
