Now we can literally build neurons
1. Brain-Like Artificial Neurons Created Scientists at UMass Amherst have built artificial neurons that mimic real brain cells with stunning accuracy. Connecting the artificial neuron to a biological cell. a. (Top) Schematic of seeding cardiac cells (cardiomyocytes) on an ultra-flexible and releasable mesh sensing system. (Bottom) Schematic of forming 3D mesh-tissue integration. b. Fluorescence optical image of a formed mesh-tissue. The red color indicates the embedded mesh ribbons. The green, blue, and purple colors indicate F-actin, 4′,6-diamidino-2-phenylindole (DAPI), and cardiac Troponin T (cTnT) in the cells, respectively. Scale bar, 0.5 mm. c. Representative recordings from four graphene sensors integrated on a mesh embedded in a tissue. The sharp spikes and broad peaks correspond to electrical action potentials and mechanical contractile signals, respectively. d. Schematic of the cell-sensor interface in the mesh-tissue system. The acquired sensing signals are amplified and f...
