Dear all,
I realized that spikes that pass synapses (e.g. stdp_connection) are not
processing a "multiplicity" value. However, some other nodes e.g. spikes
delivered from the volume_transmitter into the stdp_dopa_connection
include such a value. Does this mean, the multiplicity for spike events
that pass a synapse is always equal to 1?
Thanks!
Best Regards,
Benedikt

Dear all,
is there a possibility to turn off NEST warnings such as:
It does not influence my experiments per se, but we are currently
recording videos for our review and it just doesnt make a good
impression to have warnings popping up :)
Thanks,

Dear NEST Users & Developers!
I would like to invite you to our next fortnightly Open NEST Developer
Video Conference, today
Monday 1 February, 11.30-12.30 CET (UTC+1).
As usual, 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
The agenda for this meeting is also available online, see
https://github.com/nest/nest-simulator/wiki/2021-02-01-Open-NEST-Developer-…
Looking forward to seeing you soon!
best,
Dennis Terhorst

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,

If you are thinking of starting a CBD product business, then you should get to know the different CBD products on the market. Cannabidiol, also called cannabidiol, is a powerful phytochemical found in nature. It's one of only 47 known compounds that produce delta-9-tetrahydrocannabinol (THC) in plants.
The good news is that scientists have successfully bred several strains of plants that contain cannabidiol and made it usable as a food supplement. Some of these strains are even available online, which makes it easier for people to try out new products that they haven't tried before. Unfortunately, not every CBD product is created equal. It's important to understand the differences between these strains so that you can get a better understanding of which ones will be the most effective when used as dietary supplements. Take some time to learn more about these CBD products, because there is an abundance of information available at https://goldbee.com/.
A good way to start is by looking at the ingredients. Most of the CBD products available today are derived from a variety of different sources. Some sources include hemp, the leaves of hemp, and other plants. Other sources are not as reliable, such as hemp seed oil, hemp hurd, and other plant parts. Take the time to learn about the various components of each CBD product so that you can make a more informed decision.
One of the best natural compounds found in CBD products is cannabidiol. This substance is often used interchangeably with cannabigerol. While cannabidiol has been shown to have a number of health benefits, it has also been shown to produce some of the same side effects as other substances. In some instances, it has been shown to cause depression, and it has also been linked to memory loss and muscle weakness. This substance has also been banned in several countries because of its possible side effects.
It's important to note that some clinical trials have shown positive results with this compound. However, there are still many questions surrounding this herb. It's important that you understand why it is important to have clinical trials conducted on CBD products. If the medical community is able to determine the full potential for CBD, then it will help them come up with better medications. There may come a time when it will be possible to develop a CBD pill that produces the same positive results without the dangerous side effects.
With that said, it's important that you research different CBD products so that you're ready to enter the world of natural medicine. There are a lot of different options out there that offer great products that can help you combat a wide range of conditions. Take some time to get familiar with all of your options, and then you will be ready to get started.

HI,
I may be mistaken, but isn't the EI and IE index switched (https://nest-simulator.readthedocs.io/en/stable/auto_examples/plot_weight_m…) ?
a_EI = nest.GetConnections(I_neurons, E_neurons)
c_EI = nest.GetStatus(a_EI, keys='weight')
a_IE = nest.GetConnections(E_neurons, I_neurons)
c_IE = nest.GetStatus(a_IE, keys='weight')
for idx, n in enumerate(a_EI):
W_EI[n[0] - min(I_neurons), n[1] - min(E_neurons)] += c_EI[idx]
for idx, n in enumerate(a_IE):
W_IE[n[0] - min(E_neurons), n[1] - min(I_neurons)] += c_IE[idx]
Thanks,

Dear all,
I am looking for the details of ht_neuron model and referred to DOI:
https://doi.org/10.1152/jn.00915.2004 for details. However, I couldn't find
information on V_act_NMDA and S_act_NMDA. Can anyone please point me in
the specific paragraph/table in the paper or share a one line explanation.
I have attached a screenshot of the equation from the example notebook and
also the complete notebook for quick reference
