Action Potential | Graded Potentials
Dr Matt & Dr Mike・2 minutes read
Neurons and copper wires transmit signals differently: neurons use ions and action potentials, while copper wires pass electrons. Dr. Mike Tadarovich explains how ions like sodium and potassium create charge differences in neurons, triggering signals through excitatory and inhibitory neurotransmitters like glutamate and GABA.
Insights
- Neurons and copper wires transmit signals differently: while copper wires use electrons, neurons utilize ions like sodium and potassium in an action potential process.
- Excitatory and inhibitory neurotransmitters, such as glutamate and GABA, play crucial roles in altering a neuron's charge, either making it more positive or negative, thus influencing signal transmission.
