document.write('A fascinating paper from Gradinaru et al describes a genetically engineered mouse model of Parkinson\'s disease that expresses a photoreceptor in the neurons of a particular part of the brain - the subthalamic nucleus (STN). This area is widely thought to be the central target of the immensely therapeutic technique for Parkinson\'s known as deep brain stimulation. With this photoreceptor in place, the authors could direct laser light to that area of the brain and direactly affect neural activity...');

These two things have almost nothing to do with one another. 1) The Bennett work is, in the words of a friend, \"a cute way to make a point\" that every fMRI paper I\'ve ever read has failed to explicitly acknowled...');

document.write('Something\'s afoot when a massively parallel and distributed system shows a bottleneck in performance. We\'ve known that numerous bottlenecks plague cognition since the 1940\'s, but only with recent advances in neuroimaging have we been able to say whether these bottlenecks reflect the intrusion of executive operations (for managing goals and organizing cognitive processing) or a more passive \"queueing\" processes inherent to the selection of responses.
