Rats play hide and seek

All around the world children play hide and seek. But do animals do so too? In a recent study, scientists from the Bernstein Center Computational Neuroscience (BCCN) Berlin and the Humboldt University Berlin show that rats can quickly learn a rat-human version of the game and can easily switch between different roles – hiding and searching. The scientists suspect that hide and seek has its origins much earlier in evolution than previously thought.

Can you hear what I say?

Neuroscientists at TU Dresden were able to prove that speech recognition in humans begins in the sensory pathways from the ear to the cerebral cortex and not, as previously assumed, exclusively in the cerebral cortex itself.

Simulating the effect of transcranial brain stimulation

The long-lasting aftereffects of non-invasive transcranial direct current stimulation (tDCS) promise an alleviation of severe symptoms of diseases like depressive disorder or chronic pain. In a new modeling study, researchers from the Bernstein Center Freiburg suggest that the aftereffects observed in experiments may be a consequence of homeostatic network growth. Their model is based on the idea that the stimulation triggers a rearrangement of synaptic couplings among stimulated and unstimulated neurons, eventually leading to network remodeling and cell assembly formation.

Hidden Dynamics Detected in Neuronal Networks

Neuronal networks in the brain can process information particularly well when they are close to a critical point – or so brain researchers had assumed based on theoretical considerations. However, experimental investigations of brain activity revealed much fewer indicators of such critical states than expected. Scientists from Forschungszentrum Jülich and RWTH Aachen University have now proposed a possible explanation. They showed that neuronal networks can assume a second, previously unknown critical mode whose hidden dynamics are almost impossible to measure with conventional methods.
