Dear NEST developer,
I would like to initialize a network with neurons and connections and then
run many simulations with it. It would be great if I could build the
network one time and then deepcopy (or something similar) for each
simulation. Is something like this possible?
Thanks,
Andrew Lehr
Dear Nest Community,
When trying to reproduce Izhikevich's Simple Neuron Model with NEST
Izhikevich Neuron Model, it is spiking before reaching my V_th potential
threshold setting of 30 mV, producing results inconsistent with the
publication.
Would anybody have insight as to why the neuron is spiking early? Did I
perhaps not include a relevant NEST setting?
I compared it to an explicit implementation of the ODEs, attached, for
your reference of expected neuron response.
Thank you for any suggestions.
Best Regards,
--Allen
Dear NEST Users & Developers!
I would like to invite you to our next fortnightly Open NEST Developer
Video Conference today
Monday 28 September, 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 of topics that came
up on the mailing list or that are suggested by the teams.
Agenda
Welcome
Review of NEST User Mailing List
Project team round
In-depth discussion
Benchmarking setups for CoSim and the NRP-NEST coupling.
Special guests will be Kim Sontheimer and Cristian Jimenez-Romero of the
SimLab Neuroscience
The agenda for this meeting is also available online, see
https://github.com/nest/nest-simulator/wiki/2020-09-28-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.

Hi!
It seems to have been a while since an invitation to the bi-weekly meeting
has been sent out. Will they resume soon? I would like to discuss the topic
of extension modules and feel like the meeting is great place to get
informed.
Best regards
