How kids’ brain structures grow as memory develops

How kids’ brain structures grow as memory develops

Our ability to store memories improves during childhood, associated with structural changes in the hippocampus and its connections with prefrontal and parietal cortices. New research from UC Davis is exploring how these brain regions develop at this crucial time. Eventually, that could give insights into disorders that typically emerge in the transition into and during adolescence and affect memory, such as schizophrenia and depression Continue reading

Eavesdropping on brain cell chatter

Eavesdropping on brain cell chatter

Everything we do — all of our movements, thoughts and feelings — are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. But a new mouse study suggests that astrocytes might only be tuning in part of the time — specifically, when the neurons get really excited about something. Continue reading

Cancer drugs block dementia-linked brain inflammation, study finds

Cancer drugs block dementia-linked brain inflammation, study finds

A class of drugs developed to treat immune-related conditions and cancer — including one currently in clinical trials for glioblastoma and other tumors — eliminates neural inflammation associated with dementia-linked diseases and brain injuries, according to UC Irvine researchers. In their study, assistant professor of neurobiology & behavior Kim Green and colleagues discovered that the drugs, which can be delivered orally, eradicated microglia, the primary immune cells of the brain. These cells exacerbate many neural diseases, including Alzheimer’s and Parkinson’s, as well as brain injury Continue reading

How smells stick to your memories: Your nose can be a pathfinder

Waves in your brain make smells stick to your memories and inner maps: When I was a child I used to sit in my grandfather’s workshop, playing with wood shavings. Continue reading

Sperm meets egg: Protein essential for fertilization discovered

Researchers at the Wellcome Trust Sanger Institute have discovered interacting proteins on the surface of the sperm and the egg essential to begin mammalian life. Continue reading

Scientists re-define what’s healthy in newest analysis for human microbiome project

Scientists re-define what’s healthy in newest analysis for human microbiome project

As scientists catalog the trillions of bacteria found in every nook and cranny of the human body, a new look by the University of Michigan shows wide variation in the types of bacteria found in healthy people. Continue reading

Synapses: stability in transformation

Synapses: stability in transformation

Synapses are the points of contact at which information is transmitted between neurons. Without them, we would not be able to form thoughts or remember things. Continue reading
