Because the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct. Please include references.
Give a detailed, step-by-step description of the stages of an action potential, including a description of and explanation for the refractory periods and the rising and falling phases as well as return to rest. In your explanation, make sure to include 1) summation principles, 2) key membrane potentials (values), 3) location of voltage changes along the membrane, 4) states of the various voltage-gated channels. The more detail, the better. There are 5 main steps.
There are two types of gated ion channels. Name the 2 types and provide a description of how they work

- Assume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.arrow_forwardA neuron responds to adequate stimulation with _______, a type of self-propagating signal.arrow_forwardLocal anesthetic is often used in dentistry to lessen the sensation of pain during dental procedures.
