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.

Primed for memory formation

A new study carried out in a collaboration between researchers from LMU and UC San Diego suggests that new sensory experiences are encoded in pre-existing patterns of neuronal activity, which are recalled, modulated and enhanced following periods of behavioral activity.

Opening the Black Box of Dendritic Computing

How do nerve cells compute? This fundamental question drives LMU neurobiologists led by Andreas Herz. They have now presented a novel method to disentangle complex neural processes in a much more powerful way than was previously possible.
