An Initial clarification of what "loss of sensation" means: The history in the patient with “numbness” is extremely important. First of all, as with most neurologic complaints, you must determine what the patient means by “numbness.” Some patients are describing loss of sensitivity (anesthesia or hypesthesia) or distorted sensations (paresthesia), which ...

Units of genetic distance It took me a little while to understand what MU means. I have never seen MU but rather m.u. for map unit, or cM for centiMorgane. Solving the problem This problem got me thinking a little bit. My logic is the following: Probability of being heterozygous at the first locus You cross two individuals (we'll call them individual 1 ...

Actually there is a way to determine the initial conditions for this problem. We assume that the gating variables $r$ and $s$ are at a steady state before the membrane potential jump from$u_0$ to $u'$. If we look at the first graph(the steady state relation versus membrane potential) we can see that at the membrane potential $u_0$ that $r(t=0)\approx 0$ ...

Since you didn't get the right answer to #6, let's review the basis for this model. The basis of the model is precisely the statement in #6: an individual channel has a defined conductance when it is conducting, and if all of them are conducting then the total conductance is the single-channel conductance times the number of channels (conductances in ...
