Which type of neuron, based on its shape, is bestsuited for relaying information directly from one neuron toanother? Explain why.

When expert pianists listen to familiar, well-practiced music, they imagine the finger movements, and the finger area of their motor cortex becomes active, even if they are not moving their fingers (Haueisen & Knösche, 2001). If we regard those neurons as another kind of mirror neuron, what do these results imply about the origin of mirror neurons?

a) How does E allow faster transmission of signals?  b) What would happen if G has a lack of Calcium? c) Most neurons have the style of junction (chemical) shown in the diagram, rather than gap (electrical) junctions. Why does this make sense?

What is an example of asituation in which the neuroncell body is located in a part ofthe body and its axonalterminal portion is in anotherdistant part of the body? Whydoes this happen?

Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish. You incubate the neurons with an FM dye, and then you wash them with medium to remove the dye. You find that if the neurons are stimulated to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Can you explain why this effect may have occurred? Also, after generating fluorescent synaptic regions by this procedure, suppose that you trigger additional action potentials while continuing to wash with medium. Would you expect the synaptic regions to lose fluorescence?

According to the function ofthe transmitted neuralimpulse which are the types ofneurons? How different arethe concepts of afference andefference of the neuralimpulse transmission?

Two separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive an excitatory post-synaptic potential (EPSP) and an inhibitory post-synaptic potential (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive one excitatory post-synaptic potential that is the same sized as the EPSP and IPSP received by the other interneuron

Central nervous system (CNS) and peripheral nervous system (PNS) are two systems innervous system that control human movement and activity.(a) Describe the pathway of receiving and transferring information in neuron.

Which is the normal signof the electric charge betweenthe two sides of the neuronplasma membrane? What isthe potential difference(voltage) generated betweenthese two sides? What is thatvoltage called?

Why are sensory neurons not classified as somatic orautonomic?
