Growing in darkness…
New research reveals how a week in the dark rewires brain cell networks and changes hearing sensitivity in adult mice long after the optimal window for auditory learning has passed. With further study, cross-modal learning — the manipulation of one sense to induce change in another sense — could be used to help people with…

Not seeing the tree…
Researchers have shown how it is possible that objects stand out less when they are surrounded by similar objects. This surroundings-suppressing effect is caused by feedback from higher visual brain areas. The results of this research are important for a better understanding of the way in which the brain transforms incoming light into a cohesive…

Brain & Artificial neurons. Tears. Smiles.
Brain functions are made possible by circuits of spiking neurons, connected together by microscopic, but highly complex links called synapses. In this new study, published in the scientific journal Nature Scientific Reports, the scientists created a hybrid neural network where biological and artificial neurons in different parts of the world were able to communicate with…

Back in time…
Time, as far as we know, moves only in one direction. But in 2018, researchers found events in some gamma-ray burst pulses that seemed to repeat themselves as though they were going backwards in time. Recent research suggests a potential answer for what might be causing this time reversibility effect. If waves within the relativistic…

White noise. Dark fear.
White noise is not the same as other noise – and even a quiet environment does not have the same effect as white noise. With a background of continuous white noise, hearing pure sounds becomes even more precise, as researchers have shown. Their findings could be applied to the further development of cochlear implants. (1)…
