The New Project Set to Make EEG, Brain Computer Interfacing and 3D Printing History
Simon Oxenham covers the best and the worst from the world of psychology and neuroscience. Formerly writing with the pseudonym "Neurobonkers", Simon has a history of debunking dodgy scientific research and tearing apart questionable science journalism in an irreverent style. Simon has written and blogged for publishers including: The Psychologist, Nature, Scientific American and The Guardian. His work has been praised in the New York Times and The Guardian and described in Pearson's Textbook of Psychology as "excoriating reviews of bad science/studies”.

It's an impressive project that can push the frontiers in one field, a new crowdfunded project looks set to make a splash in three.
Until now, the research grade EEG equipment that sophisticated brain computer interfaces depend on have costed thousands if not tens of thousands of dollars. Over recent years we've seen a range of consumer brain computer interface products come on to the market amid massive fanfare. The devices aim to allow the user to control or communicate through a computer using their brain waves recorded through electrodes placed on the scalp. The devices that have so far appeared on the consumer market have a few things in common. Proprietary software places restrictions on developers and limits access to raw data for researchers. Even when data is accessible, such systems have proved unhelpful to researchers due to the fixed and limited electrode locations that don't match up with the internationally recognised system researchers use to record electrode placement.
A group based in New York is trying to change that with an open sourced EEG unit which is already nearly funded on Kickstarter that will be able to be used with existing open sourced BCI applications like BrainBay or OpenVibe. The project probably isn't suitable for amateurs just yet, but if you've got some background in EEG, coding or ideally both then this project could be a lot of fun!
In a new development, adding the cherry on the cake only at the last minute, the group have updated the Kickstarter to announce that they will also be developing the first open source 3D printed EEG headset. As if the project wasn't ambitious enough already, the plan is to allow users to drag and drop the electrode locations they wish to use on a user interface and then print a minimalist headset light enough for the EEG unit and a bluetooth transmitter to be strapped to the back.
The beauty of this project is that, in the spirit of open science, no matter if the initial iteration soars or crashes, researchers, developers and anyone else for that matter can take the designs, change them and make them better.
Open sourced systems are also a major bonus for skeptics. Without access to the data underpinning the workings of a BCI system, it can be difficult to say for sure that a primitive BCI device is anything more than a glorified divining rod. Providing access to the data will allow users to really be sure it is their brain - and not the subtle twitches of their eyebrows for example, that are controlling what is happening on their screen.
I for one welcome our new BCI overlords!
Giving our solar system a "slap in the face"
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
The climate change we're witnessing is more dramatic than we might think.
A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
