Connectomic comparison to mouse revealed massively expanded interneuron-to-interneuron networks in human. Credit: Loomba, Helmstaedter, MPI for Brain Research The analysis of the human brain is a central goal of neuroscience. However, for methodological reasons, research has largely focused on model...

(A) Cortical maps from the dataset: blockface (left), quantitative R2* (middle), and parvalbumin immunohistochemistry (right), sampled at the midcortical surface in fully folded (top) or inflated (bottom) views; (B) reconstructed blood vessels extracted from the coregistered stainings; (C) automated cortical...
You used to be able to make snap judgments in your 20s, but now it feels like you take a lot longer to react to questions, decisions and challenges put before you. Don’t fret, it’s not that you’re losing brain power. Your response time does tend to slow down as you age, but a new study...
ELSEVIER Philadelphia, December 28, 2021 – In the central nervous system, microglial cells play critical roles in development, aging, brain homeostasis, and pathology. Recent studies have shown variation in the gene-expression profile and phenotype of microglia across brain regions and between different age and disease states. But the molecular mechanisms that contribute to these transcriptomic...
CELL PRESS Neural replay during waking rest may contribute to memory consolidation of action sequences in humans, according to a study published June 8 in the journal Cell Reports. Brain imaging results revealed fast, repeated reactivation of a neural network representing a behavioral sequence that people were learning–approximately 20 times the speed of the new memory–especially...
Alison Snyder Clumps of brain cells grown in the lab provide a way to study the organ that is central to our species but is largely inaccessible in living people. Why it matters: Brain-related disorders — from autism spectrum disorders to schizophrenia to Parkinson’s disease — are a leading contributor to disability in people around the world. These...

We don’t quite understand how our own brain works – it is actually quite a big mystery. However, scientists are improving our knowledge of our central nervous system all the time. For example, now researchers from the University of Helsinki and Aalto University, in collaboration with the University of Glasgow and the University of Genoa, have identified...
INDIANA UNIVERSITY IMAGE: RICHARD BETZEL A team of Indiana University neuroscientists has built a new model of human brain networks that sheds light on how the brain functions. The model offers a new tool for exploring individual differences in brain networks, which is critical to classifications of brain disorders and disease, as well as for...
by Virginia Tech Virginia Tech researchers with the Fralin Biomedical Research Institute Center for Human Neuroscience Research construct carbon fiber microelectrodes for real-time detection of dopamine and serotonin activity in human patients. In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals—dopamine and serotonin—are at work at sub-second speeds to shape...
