PSY E111 Lecture Notes - Lecture 12: Axon Terminal, Resting Potential, Action Potential
Document Summary
After the cells reach -50mv, the cell will become more and more positive because the ion. Spreading of the action potential and repolarization. Receiving a chemical signal: action potential reaches axon terminal buttons, triggers release of neurotransmitters, bind to receptors, excitatory or inhibitory messages. Communication between neurons: stimulates adjacent ions and spread of the action potential, repolarization, negative after-potential/refractory period. Excitatory: makes it more likely that an action potential will occur in the next neuron. The neuron is at rest when it is at -70mv becomes more and more positive, reaching +30mv: if inhibitory transmitter are present, they will reduce the charge (make it more. How does the electrochemical transmission of a message between neurons work? again, and the sodium leaves the cell at a slower rate so the cell charge is now -90mv (negative after potential/refractory period) If the call body gets enough stimulation then it will give a message to the ion to open up.
