CAMBRIDGE, Mass.—The last symposium in M.I.T.’s 150-day celebration of its 150th anniversary (who ever said that geeks don’t like ritual?) is devoted to the question: "Whatever happened to AI?"
Neuroscience research involving epileptic patients with brain electrodes surgically implanted in their medial temporal lobes shows that patients learned to consciously control individual neurons deep in the brain with thoughts. Subjects learned to control mouse cursors, play video games and alter focus of digital images with their thoughts. The patients were each using brain computer interfaces, deep brain electrodes and software designed for the research.
A recent study in Cognition and Emotion found that anger can sometimes make us more critical thinkers by inhibiting our confirmation bias. Instead of only searching for information that supports our beliefs, anger can create a “moving against” tendency that motivates us to seek alternative information that opposes our assumptions.
There are billions of neurons in the brain and at any given time tens of thousands of these neurons might be trying to send signals to one another.
Love hurts, and that is not just a saying for the broken hearted. Heartbreak is a very strange distress. It is exquisitely painful, and yet we cannot find an injury on our body.
In 1992, a team at the University of Parma, Italy discovered what have been termed “mirror neurons” in macaque monkeys: cells that fire both when the monkey took an action (like holding a banana) and saw it performed (when a man held a banana). Giacomo Rizzolati, the celebrated discoverer, will deliver the Keynote Address at the APS Convention in Washington DC, USA, on May 26, 2011, and report on his latest findings. To tide us over until then, here’s a report on the state of mirror neuron science.
Mar. 26, 2011 — A team of Neuroscientists from NeuroCure Cluster of Excellence at Charité -- Universitätsmedizin Berlin and Baylor College of Medicine in Houston, Texas, have made a major breakthrough in understanding how signals are processed in the human brain. The paper, published in the current issue of the scientific journal Neuron , shows that a certain type of protein -- the "vesicular glutamate transporter" (VGLUT) plays a crucial part in the strength regulation of synaptic connections.
A new study implicates microRNAs as a possible molecular switch which could contribute to a risk factor for panic disorder.

21 March 2011 | By James Verrinder US— Neuromarketing agency NeuroFocus has launched a new wireless headset to measure respondents’ brainwave activity in more natural settings, both in and out of home. The Mynd headset has been in development for the past three years.

In the race to build computers that can think like humans, the proving ground is the Turing Test—an annual battle between the world’s most advanced artificial-intelligence programs and ordinary people. The objective?
