Spike sorting algorithms aim at decomposing complex extracellular signals to independent events from single neurons in the electrode’s vicinity. The decision about the actual number of active neurons is still an open issue, with sparsely firing neurons and background activity the most influencing factors.

The first installment of data has been released for the Mouse Brain Architecture Project, at a “mesoscopic” scale corresponding to brain regions in classical neuroanatomy. The goal of the Mouse Brain Architecture (MBA) project is to generate brainwide maps of inter-regional neural connectivity. Read the rest of this entry…

Advances in brain-computer interfaces, restorative neurotechnology, and assistive robot technology reported in Nature by the BrainGate2 collaboration of researchers, allowed two people with tetraplegia to reach for and grasp objects in three-dimensional space using robotic arms that they controlled directly with brain activity.
