What is your estimate for the gNa and for gK? If you are more comfortable, use PNa and PK. Remember, these values should be between 0 and 1. What is the resting membrane potential for this cell? Draw an action potential for this neuron in this solution. Keep in mind that this neuron is in unusual solutions. Label each axis and indicate inward and outward currents.

The recent spotlight on glial cell function has revealed numerous ways in which these cells influence nervous system physiology, but how these roles manifest during CNS development remains unknown.

Do microglia help “sculpt” the brain during development?arrow_forward

Although the procedure calmed patients, it had side effects such as apathy and a seriously disrupted personality.
