Now, the findings of a Harvard Medical School study conducted in mice challenge that model, revealing that the neurons responsible for such tasks may be less stable, yet more flexible than previously believed. The results, published Aug. 17 in the journal  Cell , cast doubt on the traditional notion that memory formation involves hardwiring information into the brain in a fixed and highly stable pattern. The researchers say their results point to a critical plasticity in neuronal networks that ensures easier integration of new information. Such plasticity, the researchers said, allows neuronal networks to more easily incorporate new learning, eliminating the need to form new links to separate neurons every time. Furthermore, they said, once a memory is no longer needed, neurons can be more easily reassigned to other important tasks. "Our experiments point to far less stability in neurons that link sensory cues to action than we would have expected and suggest the presence ...

MIT neuroscientists have proven, for the primary time, that recalling a reminiscence requires a “detour” circuit that branches off from the unique reminiscence circuit. This low-magnification picture exhibits that hippocampal CA1 neurons ( crimson ) and dorsal subiculum neurons (inexperienced) could be genetically recognized utilizing two totally different protein markers. Credit score: Dheeraj Roy/Tonegawa Lab, MIT When we now have a brand new expertise, the reminiscence of that occasion is saved in a neural circuit that connects a number of elements of the hippocampus and different mind constructions. Every cluster of neurons might retailer totally different points of the reminiscence, similar to the situation the place the occasion occurred or the feelings related to it. Neuroscientists who research reminiscence have lengthy believed that once we recall these reminiscences, our brains activate the identical hippocampal circuit that was activated when the reminiscen...

As a way to obtain higher mind sign transmission high quality, the researchers apply contact gel. Credit score: Michael Veit Filtering info for serps, appearing as an opponent throughout a board sport or recognizing photographs: Synthetic intelligence has far outpaced human intelligence in sure duties. A number of teams from the Freiburg excellence cluster BrainLinks-BrainTools led by neuroscientist non-public lecturer Dr. Tonio Ball are exhibiting how concepts from laptop science might revolutionize mind analysis. Within the scientific journal  Human Mind Mapping  they illustrate how a self-learning algorithm decodes human mind alerts that had been measured by an electroencephalogram (EEG). It included carried out actions, but in addition hand and foot actions that had been merely considered, or an imaginary rotation of objects. Though the algorithm was not given any traits forward of time, it really works as shortly and exactly as conventional methods which...
