Do We Have The Freedom Of Choice?

... with its environment. It fires an action potential when a correct signal is received from the outside - be it another neuron or a scientist's electrode or from the inside if the trigger is induced by its own genetic products. But in both cases, the reason for the neural impulse is purely electrochemical ...

QRS complex

Why does the size and other features of the QRS complex vary according to the orientation of the electrodes? one is positive(active) electrode in left leg , negative(reference) electrode in the left arm and the earthing in the Right arm. second one is with positive(active) ...

measuring action potential outside of neuron

... as others in this forum, well, i want to ask about the measuring of action potential in neuron cell, often we measure the potential membrane by electrode in the intracellular compartment. in normal condition(no transmit impulse) ,potential membrane measured about -70 mV. One day, mo college ...

Re: Running SDS PAGE for the first time!

Thanks JackBean, I read somewhere that when the running solution contains Tris-Tricine, separate electrode buffers need to be implemented; conversely, when Tris-Glycine is used, the buffer solutions may be the same in each electrode reservoir. I am not sure of the logic ...
