by Dennis Terhorst 13 Apr '20

13 Apr '20

Dear NEST Users & Developers! I would like to wish you all a happy Easter time and I hope you are all well despite the current circumstances. Since it is Easter Monday in some parts of the world, we will skip this meeting. I am looking forward to seeing you again in our next Open NEST Developer Video Conference on April 27th. Stay safe, best, Dennis Terhorst

Custom input for neurons
by Nicolas Martorell 06 Apr '20

06 Apr '20

Dear all, I'm new at NEST, and I've been trying to recreate a neural system from my work. This involves an IAF neuron which receives two different stimuli (they would be represented by inputs to the neuron - increases in post-synaptic potential). Since these are stimuli I control in my experiments, I need to be able to control their dynamics as the simulation progresses (for example, one of the stimuli has an exponentially larger effect as time progresses). Therefore, it's important for me to be able to control the dynamic of these inputs. However, I have not been able to find a way to do this. One idea I've had is to set the amplitude of a noise-generator to change according to a function of my choosing (going back to the previous example, it would be an exponential function). But this would require for this parameter to be changed mid-simulation, or to be assigned to a function and interpreted by NEST. Is any of this possible? Or alternatively, do you know of another way of accomplishing this? Thank you! Nicolas
