var fDesc=new Array(); fDesc[0] = "NerveSim is a simulated experiment for investigating the effects of drugs and the ionic composition (Na, K concentrations) of the bathing solution on the nerve action potential in the squid giant axon.
The intracellular membrane potential of the nerve is recorded from a 3M KCL filled glass micropipette electrode inserted into the axon and connected to an oscilloscope recording device via an amplifier. A second micropipette electrode connected to a stimulator allows stimulating current pulses to be applied to the nerve. Drugs (tetrodotoxin, lidocaine, 4AP) can be applied to the bath and the concentration of the Na and K ions can be changed."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
