during neurobio....
prof explains about the patch-clamp technique used to measure action potentials and membrane potentials. "one end of the very thin electrode will be placed next to the cell, be it oocyte or a neuron, and then a light suction force is applied at the other end to suck up part of the cell membrane to induce a break in the cell membrane. a device can be used to provide the suction force. i prefer to use my mouth. the right pressure must be applied. if too large a pressure is used, the whole cell will be sucked up" this reminds me of what ziyan told me about scgs girls using mouth to suck chemicals up the pipette. can you imagine sucking up an oocyte (from
Xenopus laevis) or a neuron? im sure action potentials will fire rapidly in various parts of your body.
anyway the prof continued, "if too little a pressure is used, the cell membrane will not be broken, then the action potential cannot be measured accurately. so you should be able to infer that, i am a very good kisser. i know the right pressure to apply."
he continued with lecturing. then out of no where, "if anyone of you is considering FYP in neurobiology, feel free to approach me. you will not only learn neurobiology techniques, but how to kiss well too!"

If limousines were extremely long, they wouldn't need drivers. You could just get in the back seat, walk through the limousine, and then get out of the front seat, and that would be where you wanted to go.
