Finding the sweet spot in brain development

Short-lived neural connections in the mouse brain help prime sensory circuits, forever affecting the mouse’s sense of touch. Neuroscientists have discovered that a receptor protein named mGluR1 helps regulate the timing of these temporary connections. …

Study reveals significant differences in RNA editing between postmortem and living human brain

Researchers have reported finding major differences between postmortem and living prefrontal cortex brain tissues as they relate to one of the most abundant RNA modifications in the brain, known as adenosine-to-inosine (A-to-I) editing.

A dog’s puppyhood can cause ‘puppy blues’ reminiscent of baby blues

Bringing a puppy home is usually a happy event, but sometimes the life change that comes with it can provoke significant negative emotions. Researchers found that almost half of dog owners experience anxiety, weariness or frustration during their dog’s…

Neighborhood opportunities influence infant development and cognition

Researchers find that growing up in neighborhoods with more educational and socioeconomic opportunities has a positive impact on infants’ brain activity.

How does the human brain switch between survival tasks?

The hypothalamus is a small region of the human brain typically associated with regulating body temperature, hunger, thirst, fatigue, and sleep. But it also has another important role: helping the brain and body switch between different and opposing su…

Brain’s ‘escape switch’ controlled by threat sensitivity dial

Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic st…

Researchers identify vascular changes in the brain linked to Alzheimer’s disease

The blood-brain barrier — a network of blood vessels and tissues that nurtures and protects the brain from harmful substances circulating in the blood — is disrupted in Alzheimer’s disease. Now, researchers have uncovered unique molecular signatures …

Light-weight microscope captures large-scale brain activity of mice on the move

With a new microscope that’s as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments.

Personalized magnetic stimulation may help in treating depression

Not all patients with depression respond to medication. Two recently published studies provide additional information on how an alternative treatment, transcranial magnetic stimulation (TMS), could be further enhanced. Researchers developed more precis…

The hippocampus, the cerebral conductor of our daily priorities

How does our brain distinguish between urgent and less urgent goals? Researchers explored how our brain remembers and adjusts the goals we set ourselves on a daily basis. Their study reveals differences in the way we process immediate and distant goals…
