Hello guys I began thinking about how neural models could be used in a cybernetic context, specifically in economic processes. I wrote a Medium post regarding this and i wish to pursue it as a side project. If anyone i… --- ## [Implementing condition v value in STN (AdEx)](https://brian.discourse.group/t/implementing-condition-v-value-in-stn-adex/1397)

Hi, This is a very basic question. I just started looking into Brian. I understand it is a spiking neural network simulator. Even the example for a “Rate model”, the threshold condition is set to Poisson, so that Poisso… --- ## [Pattern recognition in Spiking Neural Nets using Brian2](https://brian.discourse.group/t/pattern-recognition-in-spiking-neural-nets-using-brian2/141)

Hello! I’m Kyle, a PhD student under Chris Rozell at Georgia Tech, working on closed-loop control methods for neuroscience. I thought I’d share what I’m doing here in case anyone is interested or knows of existing code t… --- ## [Turning current on and off and connecting it into a subpopulation of neurons](https://brian.discourse.group/t/turning-current-on-and-off-and-connecting-it-into-a-subpopulation-of-neurons/740)
