Sequential firing of hippocampal neurons during both running and rest is believed to contribute to episodic-memory encoding. In particular, sharp-wave (SPW) sequences, which normally occur during rest, have been suggested to serve as a physiological substrate of memory. This hypothesis arose because (i) elimination of SPW sequences impairs learning and memory and (ii) the similarity of some SPW sequences to average running sequences (such as place-cell and episode-cell sequences) creates the impression that SPWs “replay” an animal’s experience of running. Using these average running sequences as templates, it has been shown that SPWs can replay the running sequences in both forward and backward directions relative to the templates. This led to the conjecture that SPW sequences are the sequences that are activated bidirectionally (i.e., forward and backward).
We used a novel method to test this bidirectionality conjecture by directly comparing pairs of SPW sequences without the use of average running sequences. Assuming that SPW sequences can be activated in both forward and backward directions, correlations among SPW sequences should be both positive and negative. Surprisingly, our analysis of correlations among SPW sequences revealed a very significant number of positive correlations but only a chance-level number of negative correlations. This lack of negative correlations among SPW sequences suggests that SPW sequences are activated unidirectionally, not bidirectionally as previously conjectured. This same method was also robust enough to reproduce the seemingly contradictory findings that SPW sequences are positively and negatively correlated with running sequences. More than suggesting that backward SPW replay does not exist, this analysis questions the entire “replay” framework since SPW sequences are statistically correlated positively with each other regardless of their similarity to running sequences.

Former, partager, collaborer en bibliothèques
Cet article est destiné à ouvrir une discussion autour de nos pratiques actuelles en terme de partage et de collaboration. Les exemples donnés dans cet article sont tirés de ce que je connais. Cela fait pencher la balance du côté des bibliothèques académiques.
De même, le titre laisse penser que seules les bibliothèques sont concernées. Ce n'est pas le cas. Mais là encore, il s'agit de ce que je vois de mon point de vue. Ainsi, si vous avez des exemples et des idées provenant ou destinées aux bibliothèques de lecture publique, scolaires ou d'entreprise, aux centres de documentation, archives ou autres types d'institutions que j'ai oubliées de lister ici, partagez-les ! Cet article a été rédigé sur Authorea et peut être commenté directement en ligne: cest.la/hors-texte (pour plus de précisions, rendez-vous à la fin de l'article).

Social media: the more we share the more we learn
and 2 collaborators
One day I received an email from a researcher who is living in Japan. He said there’s something wrong with my supplementary data set which was published in a paper in 2014. Apparently there was a miss-location in one of the coordinates. Recently, I received an email from a fellow researcher from UK asking for my availability to be the co-PI (Principal Investigator) on a project. Both researchers said they know me and my work from social media. I even got invited for a coffee science-talk originating from a “mention” on Twitter.
Although Indonesia is the 4th most populated country in the world, it doesn’t make our research have more impact. This is mostly due to language barrier and limited network. For years we tend to do research only as personal or organizational event, no more and no less. Nevertheless, out of that manner, we demand acknowledgment, citations, and better yet we use that citation counts to judge who are more prominent than others. Research had been placed as a closed-loop activity, with no attention from others except the team member itself. More and more research will ended up as closed report and then locked up in somebody’s drawers or some dusty shelves in the library. Social media could be the answer we’ve been looking for. Continue reading and we will show you that it is the answer we’ve been looking for. Please kindly visit my ScienceOpen interview with Jon Tennant.
Before we know and use social media, as academics living in a developing country, we have suffered from brain drain, lack of ideas, lack of facilities, lack of information and limited network. Today, we can harvest ideas in a snap, add some thoughts, and having more ideas in return. We can exchange ideas with people from the other side of the globe (or other part of the world, for those who believe the earth is flat-your choice). We know about the latest work/ scholarship offers within minutes. It is that easy. We read more science than ever before; we learn from it and disseminate it further. Borrowing @Thesiswhisperer ’s words “When I read the tweets of others I consume their thoughts and ideas”. We believe people now capture ideas more quickly from social media feeds. Instead of have a direct conversation, most of us are now skillful in fast reading and typing to explain something in less than 160 characters.
So you might ask what did we and so many others do on social media. Did we just create and respond to random posts or chats, spend more time on it than on our real work, the one we get paid for? No, we simply share what we know and re-tweet others’ that we thought would be valuable for our followers. It could be an inspirational one, a knowledge-driven one, or even a funny one. We don’t intend to brag (or humblebrag) about what we do, we’re just letting others know what we have achieved, and what we have not due to many obstacles. Share the ones we know and the ones we don’t. A kind soul would step forward and tell you what’s wrong with your work and how you can make it more sound.
Many times, we just send out words. We don’t know who would read nor deeply care about them, but oftentimes people just show up and send us their opinions, corrections, and inputs to expand and enrich our work. On the other hand, simplest rule of nature applies, “you reap what you sow”. Social media is a giant ‘take and give’ spyder web. We share solutions, instant help, or just send our sincere and deepest sympathy. In the future, others will help you in a way you could never predict. Our number one motto as healthy and breathing academics is ‘the more we share the more we learn’. Isn’t it a wonderful way to live our life?
