and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals‚ and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically‚ neurons are five to six orders of magnitude slower than silicon logic gates. Neural events happen

What is the functional difference between a neuron and a nerve? A neuron is a nerve cell and is a basic building block of the nervous system. Neurons also have special functions‚ like transmitting information throughout the body. A nerve is a bundle of neuron cells. B. What gives a multipolar neuron its name? A multipolar neuron contains several

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Exercise 3 Neurophysiology of Nerve Impulses Activity 1 1. What happens to the resting membrane potential when extracellular K+ concentration is increased? -The resting membrane potential will become more positive when K+ concentration is increased. 2. Explain why the resting membrane potential had the same value in the cell body and in the axon. -The resting membrane potential has the same value in the cell body and the axon because the typical resting membrane potential is the same throughout
