Filip Blaštík - Noise generation after stimuation problem

by Filip Blastik

To whom it may concern, I am writing regarding the problem with giving my topology network noise after simulation with the signal. The network is oscillating with noise generator which is created as single layer which provides noise for other nodes (which consist of layers). I stimulate my network with stronger signal(another different layer) and after the simulation the Nodes stop reacting to the noise input and become stuck on refresh Voltage and its for longer periods than refractory period. The model is derivation of Hill-Tononi example network. The Nest is running on Ubuntu 20.04 , Conda/Spyder The nest is version v2.20.1 To visualize the problem here are the images which illustrate the problem [image: image.png] [image: image.png] Here is the snippet of the code with the connections and layer setups Best regards Bc.

NEST pool allocator

by Itaru Kitayama

Hi, If Tiziano who wrote the code could enlighten me on understanding further of the code that'd be great, but in case he left already could the Community can jump in?; The "chunks" are clearly dedicated to Nodes, but I wonder if there are cases chunks are used for other objects? Thanks, Itaru.
