I am a careful reader of scientific literature and an avid searcher for already published material in peer reviewed journals. Of course, arxiv is essential to accomplish this task and to satisfy my needs for reading. In these days, I am working on Dyson-Schwinger equations. I have written on this a paper (see here) a […]...

A new paper in the Journal of Neural Engineering describes Facilitation of memory encoding in primate hippocampus by a neuroprosthesis that promotes task-specific neural firing The research – from Sam Deadwyler’s team at Wake Forest University (and funded by DARPA) really is pretty amazing – if it pans out. Four Rhesus macaques were trained to […]The post Augmenting Memory With A Neuroprosthesis appeared first on Neuroskeptic.... Read more »

Humans have a visual bias: everything in vision seems easy and natural to us, and it can seem a bit of a mystery why computers are so bad at it. But there is a reason such a massive chunk (about 30%) of cortex is devoted to it. It’s really hard! To do everything that it […]... Read more »

At this time of year, people are fond of telling scary tales – generally involving ghosts, ghouls, and other frightening creatures. Neuroscientists have their own horror stories, however – more niche, perhaps, but no less terrifying. Picture the scene: a group of PhD students are gathered around a flickering MRI console. The elder of the […]The post Tales of Neuro-Terror appeared first on Neuroskeptic.... Read more »

Serious gaming is big business. Many organizations – companies, schools, NGO’s – use games for training purposes, to engage customers, to advertise and to simulate important and critical situations. It is likely that you have been playing a game that was designed with the purpose of teaching you something, getting you to drink more milk or training your cooperative skills.

I don't think I mentioned this JISC project by David Shotton et al. yet, and should perhaps have done so earlier. But it is not too late, as Shotton is calling out for help in a Nature Comment this week (doi:10.1038/502295a). Now, I have been tracking what is citing the CDK literature using CiteUlike since 2010, and just asked the project developers how I can contribute this data.
Interestingly, the visualization from OpenCitations.net is interesting as it also shows papers citing papers t........ Read more »

My preferred job title is ‘theorist’, but that is often too ambiguous in casual and non-academic conversation, so I often settle for ‘computer scientist’. Unfortunately, it seems that the overwhelming majority of people equate computer scientists to programmers or some general ‘tech person’, forgetting M.R.
