This illustration shows a synapse. When an action potential arrives at a synapse, the positive charge causes the opening of voltage gated calcium channels. Calcium pours into the synaptic button and binds to several proteins, changing their shape. The activated proteins dynamically rearrange the blue cytoskeleton to transport green vesicles filled with yellow neurotransmitters to the synaptic cleft, which is filled with red adhesion proteins. Calcium-activated SNARE proteins bind to both the

Normal brain, coloured (MRI) scan. Sagittal view of a human head and neck, showing the brain and upper spinal cord (red/orange). The cerebrum (folded region) is the largest part of the brain and is made up of two hemispheres. It is responsible for conscious thoughts and actions, memory and personality. The branched structure at the back of the brain is the cerebellum, which controls voluntary movement and maintains posture and balance. Credit: SOVEREIGN, ISM/SCIENCE PHOTO LIBRARY
