How the brain keeps its options straight at decision time (opens the original)
Read excerpt
A new study by neuroscientists in The Picower Institute for Learning and Memory at MIT shows how the brain encodes information throughout the decision-making process to keep options clearly in mind and to ensure that chosen and unchosen options are remembered. The key, the researchers show in the journal iScience, is that the brain convenes ensembles to produce coordinated patterns of electrical activity that distinctly represent and sort options, both during consideration and after choice. “It
Cognition and consciousness arise from analog computations, says new theory (opens the original)
Read excerpt
A new theory, published in The Journal of Neuroscience by three scientists in The Picower Institute for Learning and Memory at MIT, offers an explanation of how the brain produces cognition and consciousness: It uses traveling waves of rhythmic neural activity to coordinate nimble neural networks with analog computations. The metaphor that the brain operates with “circuits” is incomplete, says Picower Professor Earl K. Miller, the paper’s senior author. Indubitably, the brain’s physically connec
Brain circuit keeps tabs on what just happened to aid judgment of what’s happening now (opens the original)
Read excerpt
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what’s going on around it. On one hand, it has to be open to whatever new sensory information may come its way, but on the other hand, just to keep up, it has to try to leverage prior experience to make predictions about what seems to be happening. In a new study published in Science, MIT neuroscientists identify a circuit that links a sensory decision-making region with one that advises it

Electric fields help guide neural activity, even from moment to moment (opens the original)
Read excerpt
It’s a fact of life that the electrical activity of neurons will vary during repetitions of the same task, even when the ultimate outcome is the same. A new study shows that a lot of ongoing fluctuations in the brain’s activity could be explained by the influence local electric fields exerted on the neurons, a phenomenon called “ephaptic coupling.” The finding, published in Cerebral Cortex, adds to evidence that the brain’s electric fields act as important control signals for underlying brain fu
