| 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. |
| Feeling connected to nature linked to lower risk of snake and spider phobias Posted: 24 Feb 2022 06:10 AM PST A study of over a thousand people in Hungary has found for the first time that people who feel more connected to nature are less likely to be affected by snake and spider fears or phobias. |
| Smart packaging could improve how older adults take medication Posted: 24 Feb 2022 06:10 AM PST Older adults are open to using smart packaging to improve their medication-taking experience, a new study finds. |
| Touch sensitive brain cells controlled by micromagnets Posted: 23 Feb 2022 05:28 PM PST 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. |
