    Go back! It's a trap! They're going to expect you to work from now on!

    To be honest, I have felt like cheap and exploited labour through university life as a grad student.

    So what's your thesis?

    I knew how to Google, so my lead prof. exploited that.

    I made an ion-conductance model of persistence dynamics in a known biological neuron and extended it to the biological network. Persistence dynamics are found across species and typically involve a "switch" (a particular kind of stimulus on the neuron) to switch it from typical threshold-type neuron dynamics to persistent spiking for some duration. It's involved in some cognitive functions (the persistence acts like a sort of information memory) and basically anywhere you have rhythmically contracting muscle (like birth, egg laying, breast-feeding let down, etc).

    What time frame is the persistence ? seconds ? Hours ?

    The biological neuron goes on for about half hour in a persistent state, then enters a refractory period where it can still respond as a typical threshold-type neuron but can't enter persistence mode for nearly a day. My model doesn't include any of this behavior as I put focus on developing the dominant current channels and their 2nd messengers, as well as the calcium-dependent channels responsible for persistence. So my model goes into persistence indefinitely. The refractory period requires some more elaborate 2nd-messenger modeling, I decided to go to the network and focus on onset and spread in the network and leave refractory period to the next lucky grad student.

    Congratulations! If you made it this far, you'll almost certainly survive the oral defense unless you have a total meltdown.

    When I emerged from my dissertation defense, some of my fellow graduate students were waiting to haul me off to a campus watering-hole. :biggrin:

    Thanks for the congrats, everyone!

    I think my defense will go fine. I'll probably get grilled a bit, but that's the nature of the beast.

    Can you send me a pre-print so I can pick it apart and send my objections to the qualifying committee? :oldsmile:

    I'll send you a copy of the rebuttal first, before I send it to the committee, promise :oldtongue:
