Scientists identify a new kind of human brain cell

Researchers discover a new type of human brain cell that has never been seen in mice and other laboratory animals. These 'rosehip neurons' may play a role in fine-level control between regions of the human brain, and their absence in rodents suggests difficulties in modeling human brain diseases.

Self-tuning brain implant could help treat patients with Parkinson's disease

A new, fully implanted deep brain stimulation device uses real-time brain signals to fine-tune its signaling, reducing side effects and improving symptom control in Parkinson's patients. The adaptive system was shown to be equally effective as traditional stimulation methods in initial short-term studies.

Less is more when it comes to developing bigger brains

Researchers used mathematical models to re-enact brain development in humans, monkeys, and mice, finding that the human brain requires fewer initial cells to grow. The study suggests that humans may have adopted a different developmental program to produce neurons efficiently within a longer gestational period.

New 'brain health index' can predict how well patients will do after stroke

A new computer programme assesses whole brain deterioration and predicts cognitive function after stroke up to ten times more accurately than current methods. The 'brain health index' can quantify visible brain injury from cerebral small vessel disease and brain atrophy, giving early warning of risk of future cognitive decline.

Is whole-brain radiation still best for brain metastases from small-cell lung cancer?

A recent study found that stereotactic radiosurgery (SRS) can improve overall survival and reduce cognitive side-effects in patients with brain metastases from small-cell lung cancer. The study compared outcomes of 5,752 patients who received whole-brain radiation therapy (WBRT) to those of 200 patients who received SRS.

Looking deeper into brain function

Researchers propose a new concept to uncover connections between brain regions and cognitive functions, using a bottom-up approach. Recent advances in statistical methodology and brain imaging data provide the basis for this new method, which could help reveal the core functions of brain areas.

Neural fingerprints of altruism

Research elucidates the neural basis of complex altruistic behavior, discovering two brain circuits that govern moral decisions in war veterans. The study used CT scans and an altruistic decision task to map brain damage and behavior, finding correlations between specific brain areas and punishment or donation behaviors.

Brain lesions and criminal behavior linked to moral decision-making network

Research finds brain lesions associated with increased risk of criminal behavior, specifically impacting the moral decision-making network. The study analyzed MRI and CT scans of individuals with brain lesions, revealing a strong correlation between lesions in the same brain network as those with criminal behavior.

HIV also targets the brain

Researchers at Stellenbosch University found that HIV affects the brain in early stages of infection, leading to decreased blood flow and brain functional impairment. The study used fMRI scans to compare brain activity of people with and without HIV, revealing a link between frontal lobe atrophy and cognitive symptoms.

A delicate crossing: Controller developed to open the blood-brain barrier with precision

Researchers at Brigham and Women's Hospital have developed a system to temporarily loosen the blood-brain barrier using microbubbles, allowing for real-time monitoring and controlled delivery of drugs to the brain. The approach offers improved safety and efficacy control for human clinical trials underway in Canada.
