Dopamine, a neurochemical often associated with reward behavior, also seems to help organize precisely when the brain initiates movements. It’s the latest revelation about the power of neuromodulators.
Algorithms that use the brain’s communication signal can now work on analog neuromorphic chips, which closely mimic our energy-efficient brains.
The electrical chatter of our working memories reflects our uncertainty about their contents.
Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.
The brain not only helps to regulate immune responses, but also stores and retrieves “memories” of them.
A new study of gene expression in sponges reveals the complex diversity of their cells as well as some possibly ancient connections between the nervous, immune and digestive systems.
