One type of brain cell may invite Alzheimer’s

Researchers found that excitatory neurons — those that are more likely to trigger an action (as opposed to inhibitory neurons, which are less likely to prompt neural activity) — are more vulnerable to accumulations of abnormal tau protein, which is i…

How marijuana may damage teenage brains in study using genetically vulnerable mice

In a study of adolescent mice with a version of a gene linked to serious human mental illnesses, researchers say they have uncovered a possible explanation for how marijuana may damage the brains of some human teens.

There’s more to blinking than meets the eye

In an unusual experiment, researchers demonstrate that the duration of a blink during conversation can influence the length of someone’s answer.

Internet-based CBT effective for treating severe depression

A large review of existing studies confirms that Internet-based CBT apps are an effective way of treating mild, moderate, and severe depression.

Wiring diagram of the brain provides a clearer picture of brain scan data

Neuroscientists have used data from the human brain connectome — a publicly available ‘wiring diagram’ of the human brain based on data from thousands of healthy human volunteers — to reassess the findings from neuroimaging studies of patients with A…

A role for microRNAs in social behavior

Researchers have uncovered a microRNA cluster that regulates synaptic strength and is involved in the control of social behavior in mammals. The researchers presume that their discovery may point to new therapeutic strategies for the treatment of socia…

In older people, type 2 diabetes is associated with a decline in brain function over 5 years, study shows

New research shows that in older people living in the community, type 2 diabetes is associated with a decline in verbal memory and fluency over five years.

Neanderthal genes give clues to human brain evolution

A distinctive feature of modern humans is our round (globular) skulls and brains. Researchers report that present-day humans who carry particular Neanderthal DNA fragments have heads that are slightly less rounded, revealing genetic clues to the evolut…

Parents’ brain activity ‘echoes’ their infant’s brain activity when they play together

Research shows for the first time that when adults are engaged in joint play together with their infant, the parents’ brains show bursts of high-frequency activity, which are linked to their baby’s attention patterns and not their own.

Molecular causes of brain injury associated with gut condition uncovered

Using a mouse model of necrotizing enterocolitis (NEC), researchers have uncovered the molecular causes of the condition and its associated brain injury.
