OCD: Brain mechanism explains symptoms

The largest study of its kind examines the brains of people living with obsessive-compulsive disorder and offers new insights into the condition.

Classifying brain microglia: Which are good and which are bad?

Microglia are important to brain function, and also seem to play a role in disease. New work offers the most comprehensive accounting of brain microglia to date and opens a new chapter in brain exploration. The researchers performed RNA sequencing of 7…

Discovering neurons that rapidly catch our mistakes

Scientists identify single neurons in the human brain that catch our mistakes and correct future behavior.

Whole-brain imaging of mice during behavior

In a new study, researchers demonstrate how functional ultrasound imaging can yield high-resolution, brain-wide activity maps of mice for specific behaviors. The non-invasive technology has promising applications for ophthalmologic, neurologic and psyc…

Friend or foe? Brain area that controls social memory also triggers aggression

Scientists have identified a brain region that helps tell an animal when to attack an intruder and when to accept it into its home.

How the brain hears and fears

What does the brain do when things go bump in the night? Researchers are looking at neural activity in the amygdala by studying how mice react when they hear a sound they’ve been taught to fear.

Depression: Ketamine prevents loss of pleasure in primates

Why do people with depression lose pleasure in daily activities? And why does ketamine help treat depression in some? A new study offers some answers.

Neurotechnology provides real-time readouts of where rats think they are

Scientists have demonstrated a new neurotechnology for reading out neural signals of position in real-time as rats run a maze, or replay it during sleep, with a high degree of accuracy, with more than 1,000 input channels, and the ability to account fo…

Novel approach improves understanding of the formation of new neurons in the mammalian adult brain

A team of researchers has developed a powerful new approach to understand the formation of new neurons in the mammalian adult brain.

Mothers whose responses to infants’ facial cues increase report stronger bonds with babies

A new study examines whether pregnancy changes mothers’ neural sensitivity to infants’ facial cues, and whether such changes affect mother-infant bonding. The study finds that increases in cortical responses to infants’ faces from the prenatal to the p…
