In step 2 the neuron is re-polarized when

NettetPart 2: Changing Neural Activity An article by Sidiropoulou et al. (2009), discusses how dopamine and cocaine experiences affect the properties of neurons. Specifically, in their relation to the generation of an action potential, which sends a signal/impulse to another neuron, muscle, or gland. When people are partaking in short-term memory activities, … NettetIn neurons, the cell enters a state of hyperpolarization immediately following the generation of an action potential. While hyperpolarized, the neuron is in a refractory period that lasts roughly 2 milliseconds, during …
