A new system that combines neural implants with the internet of things can remotely control the brain circuits of numerous animals across the globe simultaneously and independently via the web.
Astrocytes, not microglia, are responsible for constantly eliminating unnecessary and excessive adult synaptic connections in response to brain activity.
Women who breastfeed have a reduced risk of developing diabetes, a new study reports. In mouse models, lactation improved glucose tolerance and increased beta-cell mass three weeks post-delivery. Prolactin produced as a result of lactation induced serotonin production of beta cells. Findings suggest serotonin mediates the long-term beneficial effects of lactation of female metabolic health by increasing beta-cell proliferation and reducing oxidative stress in beta-cells.
The neuropeptide somatostatin improves visual processing and cognitive behaviors by reducing excitatory inputs to parvalbumin-positive interneurons in mice.
KAIST researchers have identified a new mechanism that causes tremors associated with Parkinson's disease. The findings, researchers say, overturn long standing assumptions about how tremors occur in Parkinson's disease.
