How a single nerve cell can multiply

Posted: 24 Feb 2022 08:26 AM PST

Neurons are constantly performing complex calculations to process sensory information and infer the state of the environment. For example, to localize a sound or to recognize the direction of visual motion, individual neurons are thought to multiply two signals. However, how such a computation is carried out has been a mystery for decades. Researchers have now discovered in fruit flies the biophysical basis that enables a specific type of neuron to multiply two incoming signals. This provides fundamental insights into the algebra of neurons -- the computations that may underlie countless processes in the brain.

Scientists have developed a new technique that uses microscopic magnetic particles to remotely activate brain cells; researchers say the discovery in rats could potentially lead to the development of a new class of non-invasive therapies for neurological disorders.

Predicting the chaos in Tourette syndrome tics

Posted: 23 Feb 2022 08:12 AM PST

New research into Tourette syndrome may signal that a diagnostic tool is near. Scientists have replicated and expanded on previous work to show that tics associated with Tourette syndrome have a fractal pattern. They also discovered that a key characteristic of that pattern in any individual can predict how severe the disease will become.
