Question
The diagram above shows two scenarios where a van der Graaf generator delivers a shock to a subject. In the first, the subject is elevated on a platform and isolated from building ground. In the second the subject wears and ECG electrode that is electrically connected to building ground. In which of these two scenarios do you expect the subject to experience the larger shock? Explain your answer using a circuit diagram. A squid giant axon has a normal resting potential of -61mV at typical North Atlantic temperatures of 6 degree C. If the squid is moved to an aquarium where the water temperatures is 15 degree C will the resting potential of its axon increase, decrease or stay the same? Explain your answer using theories we have explored in class. Explain the role of the sodium inactivation gate in creating the characteristic shape of the action potential in the Hodgkin-Huxley model. What would an action potential look like if the sodium inactivation age were no functioning (i.e. were always in its resting state)? Explain you reasoning. In a computational neural network, what are the analogs of neurons and synapses? What properties of the network change when the network is updated through "learning"?Explanation / Answer
(1) In the first case there will be greater shock because the body is not directly grounded. In the second case body is connected to ground by electrode which passes the discharge directly to ground. So lesser shock will be felt in second case.
