c-Fos

c-Fos is a protein that acts as a marker indicating when certain brain cells become active. When neurons are stimulated by experiences, emotions, or stimuli, c-Fos is produced rapidly. Scientists use its presence to identify which areas of the brain are involved in specific tasks or responses. Essentially, c-Fos helps researchers observe patterns of brain activity, offering insights into how the brain processes information, reacts to stimuli, or adapts to changes. It is a valuable tool in neuroscience for understanding neural function and connectivity.
