Researchers ‘bioprint’ living brain cell networks in the lab

Researchers have successfully used ‘bioinks’ containing living nerve cells (neurons) to print 3D nerve networks that can grow in the laboratory and transmit and respond to nerve signals.

New blood marker can identify Parkinsonian diseases

Is it possible that a single biomarker can detect all types of diseases related to dopamine deficiency in the brain? Yes, that’s what a research group is discovering. ‘We have observed that an enzyme in cerebrospinal fluid and in blood is a useful mark…

Living in a disadvantaged neighborhood affects food choices, weight gain and the microstructure of the brain

A new study finds poor quality of available foods, increased intake of calories from foods high in trans-fatty acids, and environments that do not foster physical activity, all prevalent in disadvantaged neighborhoods, disrupt the flexibility of inform…

New evidence indicates patients recall death experiences after cardiac arrest

Up to an hour after their hearts had stopped, some patients revived by cardiopulmonary resuscitation (CPR) had clear memories afterward of experiencing death and had brain patterns while unconscious linked to thought and memory, report investigators.

Revolutionizing brain monitoring and stimulation with thin-film neural electrodes

Flexible thin-film electrodes placed directly on brain tissue show promise for the diagnosis and treatment of epilepsy. Thanks to an innovative yet straightforward design, these durable electrodes accurately match the mechanical properties of brain tis…

All work and no play will really make a dull life

Prioritizing career goals over fun and freedom doesn’t make your life better, researchers have found. The study across three countries discovered people who prioritized achievement over enjoyment were less happy on the next day.

Potential new approach to PTSD treatment

A research study has found that cerebellar inhibitory interneurons are essential for fear memory, a type of emotional memory formation. Inhibitory interneurons within the cerebellar circuitry act as gatekeepers and control the output of the cerebellar …

Could a breakdown in the brain’s networks allow infections to contribute to Alzheimer’s disease?

New data gives more evidence to the possibility that developing a pathobiome in the brain could cause some forms of Alzheimer’s and related dementias.

New neural insights into processing uncertainty in obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a neurological disorder characterized by repeated behaviors such as cleaning and checking despite clear objective evidence of cleanliness, orderliness, and correctness. Although the disease is often mischaracteriz…

Your body’s own cannabinoid molecules calm you during stress

When you’re under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A …
