The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

AI-powered, speech-based screening tool offers new hope for early Parkinson’s detection

Computer scientists at the University of Rochester have developed an AI-powered, speech-based screening tool that can help people assess whether they are showing signs of Parkinson's disease, the fastest growing neurological disability in the world.

High-resolution whole-cortex imaging reveals neurovascular dynamics in awake mice

Neurovascular coupling (NVC) is the dynamic regulation of cerebral blood flow in response to neural activity. Specifically, when neurons become active, nearby blood vessels dilate to increase blood supply, thereby meeting the heightened energy demands associated with neural activity.

Ibogaine treatment shows major breakthrough for veterans with brain injuries

Now, Stanford Medicine researchers have discovered that the plant-based psychoactive drug ibogaine, when combined with magnesium to protect the heart, safely and effectively reduces PTSD, anxiety and depression and improves functioning in veterans with TBI.

AI-driven microscopy predicts and tracks protein aggregation in real time

The accumulation of misfolded proteins in the brain is central to the progression of neurodegenerative diseases like Huntington's, Alzheimer's and Parkinson's.

Ketamine's antidepressant effects involve the brain's opioid system

Ketamine is a highly effective, fast-acting antidepressant that works even for patients who have not responded to other medications.

Study finds continued use of risky antiseizure drugs during pregnancy

Despite evidence of the risk of malformations at birth, or birth defects, use of some antiseizure drugs during pregnancy has persisted, according to a study published on July 23, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Penn State team investigates the neural basis of nightmares and mental health

Dreams, and likely nightmares, are experienced universally across humans and animals, but neuroscientists still do not know why.

Scientists discover neuron-like communication system in the gut

In a key advance for regenerative medicine and gut health, scientists from Duke-NUS Medical School and Nanyang Technological University, Singapore (NTU Singapore) have uncovered a precise and unexpected communication system in the gut.

Innovative immunotherapy trial opens for newly-diagnosed glioblastoma patients

A UCL-sponsored clinical trial for patients newly diagnosed with glioblastoma, an aggressive form of brain cancer, has opened at UCLH's National Hospital for Neurology and Neurosurgery and Clinical Research Facility, in memory of Baroness Margaret McDonagh.

AI tool helps doctors predict hospital death risk in cirrhosis patients

Predicting who might die while in the hospital is one of the hardest challenges for doctors caring for people with serious liver disease.

AI identifies novel gene variants linked to Alzheimer’s risk

This study reveals how machine learning models uncover new genetic variants linked to Alzheimer’s, advancing predictive accuracy in genetic epidemiology.

Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.

Study reveals pandemic life made brains age faster, even without catching COVID-19

The COVID-19 pandemic accelerated biological brain aging in older adults by an average of 5.5 months over less than three years, regardless of infection status. Social disruption, age, male sex, and socioeconomic disadvantage heightened vulnerability, while only infected individuals showed measurable declines in executive function.

Research uncovers a 'neurobiotic sense' that lets the brain respond to gut microbe signals

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.

Anti-reward brain circuit may hold key to treating cocaine addiction

Why do so many people relapse after quitting cocaine? A new study from The Hebrew University reveals that a specific "anti-reward" brain circuit becomes hyperactive during withdrawal-driving discomfort and pushing users back toward the drug.

New imaging tool measures inner ear fluid to assess hearing loss

Optical coherence tomography (OCT), a tool routinely used to diagnose and plan treatment for eye diseases, has now been modified to collect images of the inner ear.

Mouse study reveals brain switch behind flee or freeze response

Researchers have identified a key neural switch that controls whether animals instinctively flee from a threat or freeze in place.

New llama antibody-based treatment improves brain function in schizophrenia models

While current treatments for schizophrenia - a mental illness affecting 1% of the world's population - can reduce certain symptoms, they have little effect on the cognitive deficits affecting the daily life of patients.

Neurons shift during repeated navigation of identical paths

In a new study, Northwestern University neurobiologists found the brain's internal GPS changes each time we navigate a familiar, static environment.

Review highlights the evolution of research related to implantable brain-computer interfaces

A review published in Advanced Science highlights the evolution of research related to implantable brain-computer interfaces (iBCIs), which decode brain signals that are then translated into commands for external devices to potentially benefit individuals with impairments such as loss of limb function or speech.
