Discovery gives insight into brain function, breakdowns
by Erik Robinson, Oregon Health & Science University Recovery from depression is accelerated by Ca2+ binding to presynaptic SYT3. Credit: Nature (2022). DOI: 10.1038/s41586-022-05337-1 Scientists at Oregon Health & Science University have identified a long-sought gene-encoded protein that enables the brain to communicate a broad range of signals across gaps between neurons, known as synapses. The discovery published...

Neurolinguists report not two, but three options for brain functional categories
by Leiden University The yellow-red color marks the seed region, the green color demonstrates negative functional interactions, and the blue color demonstrates positive functional interactions. Panel A demonstrates the left IPC caudal cluster functional connectivity when switching to L1 and panel B shows the right IPC caudal cluster functional association under the same condition.

Researchers find that blood pressure medications impact brain function
by University of Minnesota Medical School Credit: Pixabay/CC0 Public Domain Published in Science, University of Minnesota Medical School researchers found that blood pressure medications have an unanticipated effect on the brain. The research team discovered that drugs used to treat blood pressure unexpectedly increase the effect of opioids that the brain naturally produces. This can fine-tune the function of a...
