Consider non-surgical brain stimulation for severe depression, say experts

Non-surgical brain stimulation should be considered as alternative or add-on treatments for adults with severe forms of depression, suggests a new study.

Had enough water? Brain’s thirst centers make a gut check

Until recently, scientists believed that a brain region called the hypothalamus makes us thirsty when it detects a drop in the hydration of our blood. But neuroscientistts now realize that this couldn’t be the whole story.

Retinal prion disease study redefines role for brain cells

Scientists studying the progression of inherited and infectious eye diseases that can cause blindness have found that microglia, a type of nervous system cell suspected to cause retinal damage, surprisingly had no damaging role during prion disease in …

Newly discovered role for climbing fibers: Conveying a sensory snapshot to the cerebellum

Though there is a wealth knowledge supporting the idea that sensory cues benefit motor learning, the precise brain circuitry and mechanisms tying these two together has been debated in recent years. Shedding new light on this topic, new research has re…

A simple strategy to improve your mood in 12 minutes

We all have a remedy — a glass of wine or a piece of chocolate — for lifting our spirits when we’re in a bad mood. Rather than focusing on ways to make ourselves feel better, a team of researchers suggests wishing others well.

What really happens in the brain during a hallucination?

A new study reveals a surprising brain mechanism tied to the experience of drug-induced hallucinations. These findings may even have wider implications.

Untangling the brain’s life-support network

Scientists have created the first global network model of the hypothalamus – a portion of the brain that controls basic survival functions in humans and many other animals.

Mind melding: Understanding the connected, social brain

Parents may often feel like they are not ‘on the same wavelength’ as their kids. But it turns out that, at least for babies, their brainwaves literally sync with their moms when they are learning from them. In a new study, researchers found that how we…

Quick thinking? It’s all down to timing

Synaptic plasticity, which underlies learning and memory, involves the strengthening and weakening of synapses. This process is affected by the relative timing of spikes in electrical activity in the pre- and postsynaptic neurons. Researchers have now …

New ‘pulsing’ ultrasound technique improves drug delivery to brains of mice

Using rapid short-pulse sequences of ultrasound helps drugs reach the brains of mice, according to new research.
