How can our brain still perceive familiar objects even when they become indistinct?
Researchers have explored the brain neuronal mechanism that allows the perception of familiar images even if they are indistinct. They found that the number of neurons responding to low-contrast rather than high-contrast visual stimuli increased in rat…
In the quantum realm, not even time flows as you might expect
A team of physicists has shown how quantum systems can simultaneously evolve along two opposite time arrows – both forward and backward in time. The study necessitates a rethink of how the flow of time is understood and represented in contexts where qu…
