LIF neuron with both current based and conductance based synapses

by Hartmut Schmidt

Dear all, I am trying to implement a network consisting of LIF neurons with mixed current based and conductance based synaptic connections. Eg. one LIF neuron which gets two inputs from which one is treated as current input and the other as conductance input. That means, how to treat the input should be encoded in the synapse and not in the type of the postsynaptic neuron. Is such a neuron model already implemented or is there a way to implement this? Thanks for your help. Best, Hartmut

pipnest

by Robin Gilbert De Schepper

Hi, I created a little tool that provides packaging for NEST extension modules into python packages that can be `pip installed` on the target machine. https://pip-nest.readthedocs.io/en/latest/ First off, is this interesting to the community? It certainly seems easier to `pip install some-module` than to provide installation instructions, and I can now specify my modules as dependencies in code I distribute. Secondly, there are some shortcomings based on the fact that the pip install only reliably produces the build artifacts into python's site-packages and nest doesn't look for them there. This can probably only be elegantly solved by adding an `entry_point` to the nest python module so that these pip nest modules can announce themselves there? -- Robin De Schepper, MSc Department of Brain and Behavioral Sciences Unit of Neurophysiology University of Pavia, Italy Via Forlanini 6, 27100 Pavia - Italy Tel: (+39) 038298-7607 http://www-5.unipv.it/dangelo/

Training SNNs with PyNEST

by s.kraemer96＠gmx.net

Dear all, I´m writing a master thesis on spiking neural networks and how transparent they are. For that I need to implement a SNN network and train it. So I started with Brian but that is much to complex and I don´t need something special. So I decided to use PyNest. I did all the tutorials but I´m missing a tutorial how to train the network. I don´t know how to put in a dataset to train the model. I haven´t found anything to this topic. So my questions are: 1. Can PyNest train set up a SNN and train it trough data and if not is there another simulator who can do this? 2. How do I do it? Is there anything I missed to read or can someone send me an example? This would be very helpful. Thanks for your help. Best, Sonja

Open NEST Developer Video Conference Monday 8 June 2020 11:30 CEST (UTC+2)

by Dennis Terhorst

Dear NEST Users & Developers! I would like to invite you to our next fortnightly Open NEST Developer Video Conference on Monday 8 June, 11.30-12.30 CEST (UTC+2). In the Project team round, a contact person of each team will give a short statement summarizing ongoing work in the team and cross-cutting points that need discussion among the teams. The remainder of the meeting we would go into a more in-depth discussion suggested from the teams. In-depth discussions will cover updates on the ongoing discussion around #1604 (STDP and delays) and proposed refactoring of the testing framework. Agenda Welcome Review of NEST User Mailing List Project team round In-depth discussion The agenda for this meeting is also available online, see https://github.com/nest/nest-simulator/wiki/2020-06-08-Open-NEST-Developer-… Looking forward to seeing you soon! best, Dennis Terhorst ------------------ Log-in information ------------------ We use a virtual conference room provided by DFN (Deutsches Forschungsnetz). You can use the web client to connect. We however encourage everyone to use a headset for better audio quality or even a proper video conferencing system (see below) or software when available. Web client * Visit https://conf.dfn.de/webapp/conference/97938800 * Enter your name and allow your browser to use camera and microphone * The conference does not need a PIN to join, just click join and you're in. In case you see a dfnconf logo and the phrase "Auf den Meetingveranstalter warten", just be patient, the meeting host needs to join first (a voice will tell you). VC system/software How to log in with a video conferencing system, depends on you VC system or software. - Using the H.323 protocol (eg Polycom): vc.dfn.net##97938800 or 194.95.240.2##97938800 - Using the SIP protocol:97938800@vc.dfn.de - By telephone: +49-30-200-97938800 For those who do not have a video conference system or suitable software, Polycom provides a pretty good free app for iOS and Android, so you can join from your tablet (Polycom RealPresence Mobile, available from AppStore/PlayStore). Note that firewalls may interfere with videoconferencing in various and sometimes confusing ways. For more technical information on logging in from various VC systems, please see http://vcc.zih.tu-dresden.de/index.php?linkid=1.1.3.4
