Childhood trauma may leave a lasting “scar” inside brain cells

Early-life stress may physically alter how DNA is packaged in the brain, leaving stress-related genes primed to activate more easily years later. In mice, researchers were able to block this effect, preventing the heightened anxiety and stress sensitiv…

Your brain may not actually “make” decisions

A neuroscientist is challenging the idea that the brain contains a central system that actually “makes” our decisions. What we experience as choosing may instead emerge from the continuous interaction of perception, movement, the body, and the worl…

Depression may shut down the brain’s ability to make new neurons

A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories. The researchers also identified broad molecular …

Too much or too little sleep may make your body age faster

Both too little and too much sleep may be linked to faster aging throughout the body. Researchers analyzing 23 biological aging clocks found the lowest aging levels among people sleeping about 6.4 to 7.8 hours per day. Short or long sleep was also asso…

A major Alzheimer’s risk gene may shrink brain cells years before symptoms

Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neurons and making memory circuits unusually active. …

Schizophrenia’s lost brain connections follow a surprising pattern

Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain’s chem…
