When you reach out to grab an object, neurons fire telling your brain to reach and grab for the object. These are called motor command neurons and have been known about (by those who know) for about 50 years.
Researchers in Italy (PMID 24778385) recently found a subset of these command neurons called mirror neurons. Mirror neurons fire when you watch someone reach to grab an object. These neurons don’t even have to do the actual action in order to fire, all they have to do is see the action and they will fire.
Neurologist Vilayanur Ramachandra at University of California San Diego describes these neurons as empathy neurons and believes they may be involved with imitation and emulation…“because to imitate a complex act requires my brain to adopt the other person’s point of view.”
Why is this important? Learning by watching and not having to actually do a particular thing has helped to quickly spread new human behaviors across continents and populations; leap frogging evolution. For example, the use of a new tool, language or the use of fire could be learned by watching and then spread across humanity. Ramachandran says “the imitation of complex skills is what we call culture and is the basis of civilization.”

What do nuns, surgeons, and transplant recipients have in common?
No, it’s not the beginning of a joke — they’re all new MeSH terms for 2015!
I mentioned last week that I love exploring the newly released MeSH terms. Here are a few more highlights.
In the information science branch, Common Data Elements, Data Curation, Datasets as Topic, and Printing, Three-Dimensional have all been added to the vocabulary.
Social Norms, Social Skills, Courage, and Craving have been added to the behavior branch, and I’m glad to see the addition of Military Family as well.
Several forms of elimination and absorption have been added, including Intramuscular Absorption and Lacrimal Elimination.
Palliative Medicine, Electronic Cigarettes, Culturally Competent Care, and Grounded Theory also made it into the MeSH vocabulary this year.

Do you teach others about PubMed? Did you know that the National Library of Medicine has a resource page of PubMed instructional materials? The next time you’re building a class or helping a user, instead of reinventing the wheel (or the tutorial), check to see if one already exists. The resources on this page include pamphlets, handouts, slides, and videos and can be reused and adapted for your own training.
Have an idea for a different topic or format? You can contact NLM (see the link on the above website) or the NTC.

Should you start your classes with an icebreaker? Or an opener? And what’s the difference?
I think of icebreakers as a way to create a comfortable and safe atmosphere for the class or a way for participants to learn a bit about who is sharing the class experience with them. An icebreaker is typically not tied to the content of the course and can be especially useful if the class is going to meet several times or work in teams or small groups.
An opener, on the other hand, is relevant to the content and allows for a bit of networking. I like to start classes with openers because they send a message that there will be active participation in the class and prime the participants to start thinking about the subject of the training. As an opener, you might ask participants something such as:
- What question do you most want answered about X today?
- What barriers have you encountered in using X?
- What do you most often use X to do?
- What would you do if X happened?
- What’s your favorite tip for X?
In eliciting responses, you might have your participants jot down their responses first and then share with a neighbor. You might have them write on a sticky note and post it in a shared space and highlight some of the answers together.
There are many ways to engage you participants with an opener, but remember that it should be connected to the content of the session.
Share your best ideas for openers with us on Facebook or Twitter (@nnlmntc)!

In October 2013, PubMed added a new Display Settings option to sort your search results by relevance. Learn more about this feature in this 2-minute video.
You can read about this change in the NLM Technical Bulletin.

The most recent article added to the National Library of Medicine’s Technical Bulletin outlines 2 new features in PubMed.
1) A Download history link will be added to the PubMed, MeSH and NLM Catalog Advanced page History feature. This will download as a .csv file. (Click on the image to make it larger)
2) The search bar that includes a drop-down list of all the databases will be updated to show the last four databases searched at the top of the pull-down database menu. The alphabetic list with all the databases will also include the recently searched databases. (Click on the image to make it larger)

This recording covers the advantages of creating a My NCBI account, managing and manipulating your My NCBI page content using the features and options available in My NCBI. This session also identifies and differentiates between available filters on PubMed’s filter sidebar, and covers creating a custom filter.
Sometimes the audio and video portions of the recording are out of sync. If the slides don’t seem to match up with what the presenter is saying, close your browser window and reload the recording. This may fix the problem.
