Stem cell therapy restores brain function after stroke

Stem cell transplantation can reverse stroke damage, researchers at the University of Zurich report. Its beneficial effects include regeneration of neurons and restoration of motor functions, marking a milestone in the treatment of brain disorders.

Stem cell therapy shows promise for repairing brain damage after stroke

When someone has a stroke - a leading worldwide cause of death and disability - time is of the essence. Almost nine out of 10 cases are ischemic strokes, caused by restricted blood flow in the brain, and the current gold-standard treatment that breaks up blood clots must be delivered within four and a half hours of symptoms appearing.

Study uncovers how the brain flexibly switches communication routes

When we recall something familiar or explore a new situation, the brain does not always use the same communication routes.

Boosting PI31 to restore synaptic function and prevent neurodegeneration

One fundamental feature of neurodegenerative diseases is a breakdown in communication. Even before brain cells die, the delicate machinery that keeps neurons in touch-by clearing away protein waste at the synapses-starts to fail.

Scientists discover IC–encoder neurons that shape visual perception

An illusion is when we see and perceive an object that doesn't match the sensory input that reaches our eyes. In the case of the image below, the sensory input is four Pac Man–like black figures.

Novel vitamin K analogs show promise for reversing neurodegenerative diseases

Neurodegenerative diseases like Alzheimer's, Parkinson's, and Huntington's disease are characterized by the progressive loss of neurons.

Scientists uncover brain circuit that turns cravings into eating behavior

Researchers found that the bed nucleus of the stria terminalis integrates pleasure signals from central amygdala prodynorphin neurons and hunger signals from agouti-related peptide neurons to drive consumption. Manipulating this bed nucleus of the stria terminalis circuit bidirectionally altered food intake and body weight in mice.

Elinzanetant reduces hot flashes in menopause

The OASIS-3 trial demonstrates elinzanetant's effectiveness in alleviating menopausal symptoms, reducing hot flashes significantly over a year-long study.

Infection or stressful events during pregnancy may increase anxiety risk in offspring

Increased risk for anxiety may begin before birth, shaped by infection or stressful events during pregnancy, according to a new preclinical study from researchers at Weill Cornell Medicine.

Rare ABCA7 gene variants linked to Alzheimer’s risk

A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer's in some of the people who carry it.

Detecting causality in neural spike trains using a new technique

Understanding the brain's functional architecture is a fundamental challenge in neuroscience. The connections between neurons ultimately dictate how information is processed, transmitted, stored, and retrieved, thus forming the basis of our cognitive functions.

Rapid neuronal evolution linked to high prevalence of autism in humans

A new paper in Molecular Biology and Evolution, published by Oxford University Press, finds that the relatively high rate of Autism-spectrum disorders in humans is likely due to how humans evolved in the past.

New feedback mechanism in the brain could open avenues for treating people with sleep disorders

As every bodybuilder knows, a deep, restful sleep boosts levels of growth hormone to build strong muscle and bone and burn fat.

Ultrasound device enables precise non-invasive stimulation of deep brain regions

An ultrasound device that can precisely stimulate areas deep in the brain without surgery has been developed by researchers from UCL and the University of Oxford, opening up new possibilities for neurological research and treatment of disorders such as Parkinson's disease.

New 3D eye model reveals causes of steroid-related glaucoma

The eye, like most organs, has an intricate plumbing system. Pressure builds when drainage is impaired, and this condition – glaucoma – can cause irreversible vision loss.

Stress in early life alters brain cell structure and behavior in mice

Canadian researchers show that stress modifies the morphology of brain cells in mice, directly influencing the rodents' level of physical activity.

Smell loss emerges as the early behavioural sign of Alzheimer’s

Research reveals immune cells target brainstem nerves, linking smell loss to early Alzheimer's, offering potential for earlier diagnosis and intervention.

Impaired spatial orientation found in older adults at risk for Alzheimer’s disease

Individuals with an increased risk for dementia due to Alzheimer's disease can have impaired spatial orientation skills.

Genetic variant disrupts brain’s cleanup crew increasing Alzheimer’s risk

A Nature study published today and led by researchers at the University of South Florida's USF Health Byrd Alzheimer's Institute pinpoints how a genetic variant disrupts microglia - the brain's "cleanup crew" - increasing the risk of Alzheimer's disease.
