In the cerebral cortex, when somatostatin neurons become active, other nearby somatostatin neurons became active as well. The distance over which somatostatin neurons shared activity expanded in the posterior parietal cortex.
A new microscopy technique integrates existing and novel approaches to build a clearer picture of the workings of neurons in the brain. The technique captures cellular activity across large tissue volumes in greater detail than previous techniques have allowed for.
A new study published in Nature sheds light on how populations of neurons work together during working memory and decision making tasks. Researchers report individual neurons are briefly active, but populations of neurons working together carry information for longer periods of time by being active at different times.
