Changeux model

The Changeux model explains how nerve cells in the brain communicate using chemicals called neurotransmitters and receptor proteins. It suggests that receptors have multiple sites where neurotransmitters can bind, leading to a change in the receptor’s shape. This change activates the receptor and allows signals to pass between neurons, facilitating communication. The model highlights that this process is highly specific and efficient, with receptors acting like switches that turn signals on or off based on neurotransmitter binding. In essence, the Changeux model describes how brain cells translate chemical signals into electrical responses, enabling thought, sensation, and movement.
