  1. Researchers have identified a network of neurons that coordinate with other brain regions to influence eating behaviors. These findings could help those suffering from disease-induced appetite loss or over-eating.
  2. People exposed to chemical warfare agents (CWAs) often incur chronic damage to their lungs, skin and eyes, for example. They also frequently succumb to depression, anxiety and suicidal thoughts. This is shown by research on survivors from the 1988 gas attacks against Kurdish Halabja in Iraq.
  3. A new study that sheds light on how the brain processes language could lead to a better understanding of autism spectrum disorder, schizophrenia and other neurodevelopmental conditions.
  4. New research finds that serotonin is necessary for sleep, settling a long-standing controversy.
  5. Using complex statistical methods and fast measurement techniques, researchers found how the brain network comes up with the right word and enables us to say it.
  6. Researchers have discovered a secret sauce in the brain's vascular system that preserves the neurons needed to keep dementia and other diseases at bay.
  7. Researchers have discovered a mysterious group of neurons in the amygdala -- a key center for emotional processing in the brain -- that stay in an immature, prenatal developmental state throughout childhood. Most of these cells mature rapidly during adolescence, suggesting a key role in the brain's emotional development, but some stay immature throughout life, suggesting new ideas about how the brain keeps its emotional responses flexible throughout life.
  8. A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.
  9. As students learn a new concept, measuring how well they grasp it has often depended on traditional paper and pencil tests. Researchers have developed a machine learning algorithm, which can be used to measure how well a student understands a concept based on the student's brain activity patterns. The study is one of the first to look at how knowledge learned in school is represented in the brain.
  10. In sudden death in epilepsy, people stop breathing for no apparent reason and die. Now, a group of UConn neuroscientists have a lead as to why. Many neurologists argue that a bad seizure can travel through the brain to cause breathing or heartbeat malfunction, and that's what kills. But epileptics can die suddenly without having an obvious seizure. Instead, the researchers have evidence a genetic mutation that causes the seizures also disrupts the cells that control breathing.
