The teams succeeded in creating action potentials within the neurons by exciting quantum dots nearby. The stimulation of the QD created a negative charged surrounding it and opened up the ion channels in the neurons. The ion channels are vital to stimulating the brain cells by allowing positive charges to flow into the cell and create an action potential. Additionally, the action potential in neurons is what sends messages to other neurons or nerve cells within the body allowing a form of communication to occur. The goal is to use quantum dots to control the abnormal signal firing within the brain...
