New, ultra-flexible probes form reliable, scar-free integration with the brain

Ultra-flexible, nanoelectronic thread (NET) brain probes have been designed that can achieve more reliable long-term neural recording than existing probes and don’t elicit scar formation when implanted. These smaller-than-a-capillary-sized probes could…

Mouse studies offer new insights about cocaine’s effect on the brain

Researchers have determined how a specific protein regulates the brain’s response to cocaine. Their findings provide fresh insights into the neurobiology of addiction, and could lead to the development of better interventions and treatments.

Is it depression or dementia? Brain SPECT imaging helps distinguish them

Does a patient have depression or a cognitive disorder (CD) such as Alzheimer’s disease or both? Since both disorders have overlapping symptoms, how can a clinician tell them apart to make an appropriate diagnosis? Researchers have found that single ph…

Depression or anxiety may increase risk of surgical wound complications

Patients’ mental health may affect their risk of experiencing wound-related complications after surgery, new research indicates.

ADHD: Large imaging study confirms differences in several brain regions

The largest study of its kind provides robust evidence to confirm ADHD is a brain disorder characterized by delayed development of several brain regions.

Sick and tired – not just a figure of speech

Large-scale study looks at tiredness and its associations with environment, genes, and mental and physical health.Already feeling drained so early in the year?

Emotions are cognitive, not innate, researchers conclude

Emotions are not innately programmed into our brains, but, in fact, are cognitive states resulting from the gathering of information, researchers conclude.

How depression can muddle thinking

Depression is associated with sadness, fatigue and a lack of motivation. But people with depression can also have trouble processing information and solving problems. Now scientists studying a rat model for depression are identifying on a molecular lev…

Brain study: Motor cortex contributes to word comprehension

Researchers have experimentally confirmed the hypothesis, whereby comprehension of a word’s meaning involves not only the ‘classic’ language brain centers but also the cortical regions responsible for the control of body muscles, such as hand movements…

Neurotrophic factor GDNF is an important regulator of dopamine neurons in the brain

New research results are expanding our understanding of the physiological role of the glial cell line-derived neurotrophic factor GDNF in the function of the brain’s dopamine systems. In a new article, researchers establish that GDNF is an important ph…
