Researchers link defects in a nuclear receptor in the brain to autism spectrum disorders
Two University of Houston scientists are reporting that defects in a portion of the brain's hippocampus, called the dentate gyrus, is regulated by the nuclear receptor LXRβ (Liver X receptor Beta). The dentate gyrus, or ...

Mutations in neurons accumulate as we age: The process may explain normal cognitive decline and neurodegeneration
Scientists have wondered whether somatic (non-inherited) mutations play a role in aging and brain degeneration, but until recently there was no good technology to test this idea. A study published online today in Science, ...

Faster-acting antidepressants may finally be within reach
Some activity patterns in the brain can be dangerous, producing persistent dark moods that drain people's motivation, pleasure, and hope. For the past thirty years, pills like Prozac or Zoloft—collectively known as selective ...

Gene that enables memories, sense of direction produces schizophrenia-like symptoms when mutated
Mutations in a gene that should enable memories and a sense of direction instead can result in imprecise communication between neurons that contributes to symptoms of schizophrenia, scientists report.

Adult brain prunes branched connections of new neurons
When tweaking its architecture, the adult brain works like a sculptor—starting with more than it needs so it can carve away the excess to achieve the perfect design. That's the conclusion of a new study that tracked developing ...
