Prep. #6: maybe increase the stimulation intensity?
In my attempts to establish operant learning in isolated leech ganglia I'm now at preparation number 6. In my last post, I promised to show some screenshots of the software I'm using, WinEDR. Here's a screenshot of the preparation generating swimming patterns after a stimulation of ganglion 18 (click for fullsize image):And here is one showing crawling patterns in response to the same stimulation in the same preparation:The first channel is the recording from the DP nerve of ganglion 10 and the second channel is the recording of the anterior ganglion (2 or 3), which I stimulate contingently during training. The window spans 40s of recording, in case that isn't quite clear from the screenshots. This little program works really well and I enjoy doing my experiments with it a lot. Very easy, ...

Finally, some movement on the ORCID front!
WTF is ORCID, you ask? It's something scientific publishing should have had 20 years ago. It's meant to become a system that disambiguates authorship and attributions. For instance, go to PubMed and search for author 'J. Smith', and you will find out that this person has authored 17435 papers. Obviously, it is almost impossible to find or follow authors with common names. 'Open Researcher and Contributor ID', ORCID is one of the initiatives that are trying to solve this problem.Today, ORCID announced that they are launching a non-profit organization, "dedicated to solving the name ambiguity problem in the scholarly research community". Given the backing of this organization by a large number of significant players in the field, from publishers such as Elsevier or NPG, to other non-profits ...
