by Baylor College of Medicine Credit: Pixabay/CC0 Public Domain Seeking to better understand the key role the female hormone estrogen plays in maintaining energy balance and weight control, a group led by researchers at Baylor College of Medicine looked into estrogen interactions with specific brain regions that provide these anti-obesity benefits. The team reveals in...
When it comes to processing vision, the brain is full of noise. Information moves from the eyes through many connections in the brain. Ideally, the same image would be reliably represented the same way each time, but instead different groups of cells in the visual cortex can become stimulated by the same scenes. So how...
by Massachusetts Institute of Technology Inhibitory interneurons in the visual cortex (PV cells are green; SST cells are red), combine to regulate the reliability of image representation by excitatory neurons.

by Ingrid Fadelli , Medical Xpress Figure 1 All-optical method. A laser beam was precisely positioned (magenta lines) onto neurons of interest, causing those neurons to be activated (yellow shading). By observing changes in the surrounding circuit, the researchers could infer the presence of effective connections. Credit: Daie, Svoboda & Druckmann. Humans have the innate ability to...
By Rich Haridy September 09, 2020 An animal study has revealed a part of the brain activated by stress can suppress immune system activity and heighten insomnia A new study, led by neuroscientists from Stanford University, has homed in on the specific brain circuit responsible for stress-induced insomnia. The research suggests this same circuit is...
