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.

The free-energy principle explains neural network behavior


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

Social contact-seeking behavior and loneliness in the brain


Levels of the peptide amylin in the brain are related to loneliness; activating amylin neurons in the MPOA drives isolated mice to seek social contact.

Social novelty in the brain: haven’t I seen you someplace before?


Social novelty and contextual novelty are segregated in the SuM region of the hypothalamus and in projections to the hippocampus, allowing memories of meeting new people to be formed separately from memories of new places.

Cyborg cockroaches to the rescue!


The key to this remote-controllable cyborg cockroach is a solar-cell rechargeable battery and an ultrathin flexible backpack.
