Pitch perfect: Brain differences behind a rare musical ability

New research reports features of the brain in musicians with absolute, or perfect, pitch (AP) that likely enable individuals with this rare ability — shared by Mozart, Bach, and Beethoven — to precisely identify musical notes.

Rats in augmented reality help show how the brain determines location

Before the age of GPS, humans had to orient themselves without on-screen arrows pointing down an exact street, but rather, by memorizing landmarks and using learned relationships among time, speed and distance. They had to know, for instance, that 10 m…

Spinal cord is ‘smarter’ than previously thought

New research has shown that the spinal cord is able to process and control complex functions, like the positioning of your hand in external space. ‘This research has shown that a least one important function is being done at the level of the spinal cor…

Oral contraceptives could impair women’s recognition of complex emotions

Women who take the pill are nearly 10 percent worse at recognizing subtle expressions of complex emotions like pride or contempt, according to new research. Previous research suggests the relationship is causal, but the impact on women’s ability to for…

New target could help protect vision following optic nerve trauma

When a car crash or explosion results in an optic nerve injury, eliminating an enzyme known to promote inflammation appears to aid recovery, scientists report.

Could this chemical help explain anxiety?

A new study attempts to unpick the role that glutamate might have in anxiety. The findings could eventually form the basis of more effective treatments.

How exercise may protect against Alzheimer’s

A hormone called irisin — produced during exercise — may protect neurons against Alzheimer’s disease.

What causes excessive yawning?

Excessive, or frequent, yawning can arise from fatigue, anxiety, or an underlying health condition. In this article, we look at the causes and treatments for excessive yawning. We also discuss when to see a doctor.

How the brain responds to texture

New research by neuroscientists shows that as neurons process information about texture from the skin, they each respond differently to various features of a surface, creating a high-dimensional representation of texture in the brain.

Size and time impact outcomes when mechanical clot removal used for large core strokes

Patient outcomes with large core stroke damage are worse the larger the core volume and the longer the time lapse between stroke onset and treatment. Perfusion imaging may help identify large core stroke patients who are potential candidates for mechan…
