Gently stroking babies before medical procedures may reduce pain processing

Researchers found that gently stroking a baby seems to reduce activity in the infant brain associated with painful experiences. Their results suggest that lightly brushing an infant at a certain speed — of approximately 3 centimeters per second — cou…

Communication between neural networks

Researchers are proposing a new model to explain how neural networks in different brain areas communicate with each other.

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

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…
