Neurons in visual cortex of the brain ‘drift’ over time

Although other studies have documented “representational drift” in neurons in the parts of the brain associated with odor and spatial memory, this result is surprising because neural activity in the primary visual cortex is thought to be relatively stable. The study published Aug. 27 in Nature Communications was led by Ji Xia, PhD, a recent PhD graduate of […]

The fractal brain, from a single neuron’s perspective

Hacking into brain signals may be more straightforward than once thought. Physicists studying the brain at Washington University in St. Louis have shown how measuring signals from a single neuron may be as good as capturing information from many neurons at once using big, expensive arrays of electrodes. Wessel The new work continues the discussion […]
