Low cortisol, hair-trigger stress response in the brain may underlie Long COVID

A new animal study shows that exposure to immune-stimulating proteins left behind by COVID-19 leads to lower cortisol, brain inflammation and a heightened reaction to subsequent stressors.

Taming Parkinson’s disease with intelligent brain pacemakers

Two new studies are pointing the way toward round-the-clock personalized care for people with Parkinson’s disease through an implanted device that can treat movement problems during the day and insomnia at night.

Nurses play key role in addressing mental well-being for people after a stroke

The latest research indicates that 16% to 85% of people recovering from a stroke experience at least one psychosocial symptom, including depression, anxiety, stress, fatigue and/or decreased quality of life. Critical nursing interventions, such as regu…

Knocking out one key gene leads to autistic traits

Hyperactivity, repetitive behavior, and language deficits all appeared in the mice, highlighting an unexpected role the cerebellum seems to play in autism.

Brain wiring is guided by activity even in very early development

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that …

Sleep resets neurons for new memories the next day

While everyone knows that a good night’s sleep restores energy, a new study finds it resets another vital function: memory.

The brain creates three copies for a single memory

A new study reveals that the memory for a specific experience is stored in multiple parallel ‘copies’. These are preserved for varying durations, modified to certain degrees, and sometimes deleted over time.

New microscope offers faster, high-resolution brain imaging

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new app…

International study detects consciousness in unresponsive patients

New research found that brain scans can detect consciousness in some patients with brain injury who are unresponsive. In the study, 241 participants with severe brain injury who do not respond when given a simple instruction were assessed with function…

Child-parent therapy has biological benefits for traumatized kids

Psychotherapy sessions with caregivers may help prevent serious disease later in life for young children who have experienced significant trauma, a new study found.
