Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point ...
Researchers at Harvard Medical School isolated one of the brain-size genes by working with mice. When the mice were administered an increase of a gene named beta-catenin, their brains doubled in size, and they began to show more activity in the cerebral cortex [source: Cromie]. The cerebral...

"The gene MFF promotes mitochondrial fission," said Dr. Polleux. "so, when we shut off MFF, we tilted the balance, increasing fusion events. This caused the normally small axonal mitochondria to increase in length by five-to-ten-fold." Surprisingly, this increase in size did not reduce mi...

unhelpful to me at that time. Consequently, there was a therapeutic mismatch between the issues I was dealing with and the therapeutic approached preferred by the therapists. The last therapist I met with, however, met me where it mattered most to me at that time. He did it in four main...
Research indicates that drug use during adolescence can significantly increase the risk of developing a substance use disorder later in life. Early drug use may alter brain maturation and contribute to lasting cognitive impairments. Understanding the link between brain development and substance abuse can...
Chung's research into ADAR1 persisted when she launched her own research lab at Columbia in 2019. She wanted to find out why the symptoms of AGS were mostly in the brain, when RNA is found throughout the body. If mutations in ADAR1 make the immune system recognize RNA in the brain and...
Both adolescents and adults were asked how well they understood the plot of the movie and how well they understood the task in questionnaires after they conducted the task. The groups did not differ in their understanding of the plot (z = 0.48,p = 0.630) and in their understanding...
