Comment on the use of Neurons in Action software to help you understand membrane excitability

Describe the action potential conduction and neurotransmission process from one neuron to another, electrically (including saltatory conduction) and chemically. Please include peer reviewed references.

Discuss the concept of thought-controlled input devices and their potential in medical applications and assistive technology. What ethical considerations arise when using thought-controlled devices?

Quick question on the process of movement    Multiple sclerosis is a disease in which the peripheral neurons lose their myelin sheath. In this disease, voluntary movement of the limbs is slowed because;  Pick the ones that are true  the rate of opening of ligand-gated Na+ channels is decreased.   the generation of the action potential is blocked at points along the unmyelinated region due to the absence of voltage-gated channels   the action potential amplitude is degraded at the Nodes of Ranvier of the peripheral neuron.   The Schwann cells are targeted and destroyed by the immune system, affecting saltatory propagation.   the rate of opening of ligand-gated Na+ channels is decreased.

Indicate where on the neuron chemically-gated sodium channels may be located and how they work. Don't plagiarize from Google.

Consider the brain and spinal neurons. If you bathed a resting neuron with an excess of potassium ions (for example, more than 40 times higher than normal), what would be the effect on resting membrane potential?

An undisclosed drug (Drug A) is a drug that can block voltage-gated K+ channels when being introduced into the bloodstream. Explain the effects of Drug A on the action potentials produced by a neuron. If Drug A could be applied selectively to a presynaptic neuron that releases an excitatory neurotransmitter, analyse how would it alter the synaptic effect of the neurotransmitter on the presynaptic cell.

You find a neuron whose resting potential is -90mV. Which of the following are likely to be true? (select all that apply) Voltage-gated sodium channels are closed The neuron is fully permeable to sodium The neuron is permeable to potassium The neuron is hyperpolarized

Why is the action potential conducted in only one direction in a neuron?   Comments : Best of your knowledege for grasp the concept well
