Talking about a theory for neuroscience

I’m giving a talk this evening for the Philosophical Society of Washington–the abstract is here. One of the issues that jumps out whenever I give one of these talks is how neuroscience, unlike disciplines such as physics or chemistry, lacks a general theory that provides a framework or skeleton for both old knowledge and more importantly new discoveries.

As a discipline, we in neuroscience, are very good at amassing and organizing (and even sharing) data. But a general theory (analogous to say quantum mechanics or relativity)–that we are lacking. Instead we have a multitude of nascent bounded theories for various levels of organization within the brain. Hence, we have some idea of how individual neurons signal one another, how groups of neurons may act together to store memories and create perceptions, how brain diseases affect this or that brain region, and how drugs may act to ameliorate brain conditions (or sometimes create addiction). But what we lack, is a general theory of how the brain’s organization and dynamics lead to the phenomena we generally associate with brain: consciousness, creativity, deception and the like.

So that could be a very exciting thing for a discipline (i.e. the most exciting times are yet to come) or very frustrating.

I’m going to argue this evening, that perhaps we can see the vague outlines of what such a general theory might look like.

I’ll post more on this soon.

An explanation for all those bad drivers on the beltway

Suggestions of a genetic linkage to awful driving. Hmmm. I wonder if there are interactions with environmental factors?

Abstract is here.

Money quote from the UC Irvine press release:
People with a particular gene variant performed more than 20 percent worse on a driving test than people without it – and a follow-up test a few days later yielded similar results. About 30 percent of Americans have the variant.

Welcome to the the 2008-2009 Academic Year

A week from today, the Institute for Advanced Study parking lot will be jammed with parents unloading their children’s stuff–we’re adjacent to the freshman dorms here at George Mason University–and so the beginning of the academic year is unmistakable for us.

I have just returned to campus from the annual two-day President’s Council/Board of Visitor’s retreat. It’s an entirely useful exercise that informs me of the entire waterfront of activities going on at this very large public university. Beyond informing, it also is wonderful for getting into the right frame-of-mind to begin another academic year as Institute Director.
For the Institute, this marks the beginning of our eighteenth year, and our sixth since fully merging into George Mason. I count approximately 60 scientific staff, 7 administrative support folks (including myself) and two wonderful doctoral programs that fill our halls and break-out places with students. We have finished our first expansion project (we’re now approximately 35,000 square feet) and we’re going to commence the second expansion sometime during this academic year (another 12,000 or so square feet).
Most importantly, we’re doing significant science–advanced studies–at the forefront of the interface between biology, psychology and machines–“mind sciences”. Throughout my travels this past summer, I find myself reminding: I may be a neuroscientist, but I lead an institute for advanced study.
So let’s focus on the trans-disciplinary science that our illustrious founders chose as putatively fruitful–cognition across the intersection of computer sciences, neurobiology and cognitive psychology. 
Good luck for a successful year!
