The free-energy principle explains neural network behavior


Scientists show that the free-energy principle can explain how neural networks work.

Blood cell mutations linked to leukemia are inevitable


Researchers show that blood cell mutations increase with age identify risk factors for developing leukemia in Japanese and European populations.

Mathematical model predicts self-organized learning in real neurons


The free energy principle predicted how real neural connections changed as neurons “learned” in a dish.

Microcolumns: elementary neuronal units that carpet the (mouse) brain


A hexagonal lattice organizes major cell types in the cerebral cortex, with similar cells synchronizing their activity in microcolumns.

Super-thin wearable electronics just got more flexible


A method for making super-flexible and ultra-thin wearable electronics uses water-vapor plasma to create gold-gold bonds.

Gut bacteria double team worsens symptoms of multiple sclerosis


Joint activity of two gut bacteria leads to excessive MOG-specific T-cell activity and demyelination of neurons in the spinal cord of a mouse model of multiple sclerosis.
