Artificial Memories and Circular RNAs

Recording from populations of head-direction cells across brain states, Peyrache and colleagues provide an experimental demonstration of the existence of a self-organized ring attractor: the sequential activity of head-direction neurons observed in the waking mouse persists during sleep, and this 'neuronal compass' always points toward well-defined directions. The cover of April 2015 Nature Neuroscience depicts the probabilistic compass 'needle' (heat map ring) decoded from neuronal activity as the animal is exploring its environment...
