Breastfeeding duration associated with cognition

Breastfeeding duration is associated with improved cognitive scores at ages 5 through 14, even after controlling for socioeconomic position and maternal cognitive ability, according to a new study published this week in PLoS ...

Scientists identify how the brain links memories

Our brains rarely record single memories—instead, they store memories into groups so that the recollection of one significant memory triggers the recall of others connected by time. As we age, however, our brains gradually ...

Neuroscience

Scientists build subcellular map of entire brain networks

Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level—a few billionths of a meter, while also capturing ...

Using ketamine to find an undiscovered pathway in depression

For the 280 million people suffering from depression globally, relief cannot come fast enough. Monoaminergic antidepressants, including selective serotonin reuptake inhibitors (SSRIs) take weeks to months to take effect and ...

Catatonic person's body may be frozen, but their minds are not

Occasionally, as a doctor, I am asked to see a patient in the emergency department who is completely mute. They sit motionless, staring around the room. I lift up their arm and it stays in that position. Someone takes a blood ...

Capturing cortical connectivity close-up

The brain is made up of a complex series of networks—signals are constantly bouncing between those networks to allow us to experience the world and move through it effectively.

Type 2 diabetes accelerates brain aging and cognitive decline

Scientists have demonstrated that normal brain aging is accelerated by approximately 26% in people with progressive type 2 diabetes compared to individuals without the disease, reports a study published today in eLife.

Genetics

A subtle genetic change gives new clues about epilepsy

Sometimes, even the alteration of a single nucleotide in a gene can cause serious disease. In a young boy with epilepsy, this kind of mutation has not just affected the functioning of the protein in question—it could also ...

Gabapentin may boost functional recovery after a stroke

The drug gabapentin, currently prescribed to control seizures and reduce nerve pain, may enhance recovery of movement after a stroke by helping neurons on the undamaged side of the brain take up the signaling work of lost ...

Neuroscience

A new statistical method for improved brain mapping

Brain mapping involves finding the brain regions associated with different traits, such as diseases, cognitive functions, or behaviors, and is a major field of research in neuroscience. This approach is based on statistical ...
