In research that could be useful in making more capable robots, Brown University mathematicians developed an artificial neural network that can dynamically reproduce all sorts of animal walking and running movements.

Researchers at Brown’s Carney Institute for Brain Science identified a pair of neurons that integrate sweet and bitter signals to decide whether something is safe to eat.

The findings could help clinicians use neuropsychiatric symptoms to prepare patients and families for a type of dementia previously only diagnosed via autopsy.
