What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology.

Targeted Immune Cells Destroy Brain Tumors

Researchers have created a "molecular GPS" to guide immune cells directly to the brain, enabling precise targeting of tumors like glioblastoma. These cells use a unique protein code to navigate and attack cancer while sparing healthy tissue, offering a safer alternative to traditional treatments. In mice, this technology successfully cleared tumors, prevented recurrences, and reduced brain inflammation in models of multiple sclerosis.

A Novel Pain Signaling Complex Discovered

Researchers identified a new receptor, neuropilin-1 (NRP1), which collaborates with a known receptor to regulate pain signaling from nerve growth factor. Unlike traditional signaling receptors, NRP1 acts as a co-receptor to enhance pain signals without directly transmitting them. The study showed how blocking NRP1 or disrupting its interaction with nerve growth factor could offer novel approaches to pain treatment.

Antipsychotics Worsen Behavior in Dementia

A study of 500,000 Canadian nursing home residents found antipsychotic medications significantly worsened behaviors in patients, with nearly 68% experiencing increased issues. Antipsychotics are often prescribed "off-label" for dementia-related symptoms, despite serious side effects like tremors and cognitive decline. Researchers advocate for person-centered care, emphasizing non-drug therapies like music, art, and exercise to address behavioral issues.

Facial Expressions of Pain Are Linked to Distinct Brain Activity

Facial expressions triggered by pain are deeply tied to brain activity, revealing distinct neural mechanisms compared to verbal pain reports. Researchers developed a neurobiological model, using MRI and machine learning, to predict pain-induced facial expressions.

Gene Defect Linked Brain Size and Social Behavior in ASD, Schizophrenia

A new study reveals how genetic deficits, particularly in the Tbx1 gene, are linked to reduced brain volume and altered social behavior, findings relevant to autism and schizophrenia. Researchers observed smaller amygdala volumes in Tbx1-deficient mice, a brain region key to emotional regulation and social behavior. These mice displayed less interest in social interaction, relying more on non-social cues like bedding preferences.

Adult Neurogenesis Fuels Verbal Learning and Memory

Adult neurogenesis, the creation of new brain cells, supports verbal learning and memory. Using brain tissue from epilepsy patients, researchers discovered a direct link between fewer immature brain cells and cognitive decline, particularly in verbal learning and memory.

Mapping the Brain’s 24-Hour Clock

Researchers have created the first complete map of the circadian clock in the Drosophila brain, revealing it consists of at least 240 neurons—far more than previously thought. This detailed map shows similarities between the clock mechanisms of insects and vertebrates, offering new insights into how rhythms like sleep, feeding, and hormone release are coordinated.

Parallel Pathway to Long-Term Memory Discovered

New research reveals that long-term memory can form independently of short-term memory, challenging long-standing theories of memory formation. Scientists discovered this through experiments on mice, where blocking short-term memory didn’t prevent the creation of long-term memories.

New Appetite Regulating Neurons Discovered

Researchers have identified a previously unknown population of neurons in the hypothalamus that play a critical role in regulating appetite. These neurons express both leptin receptors and the BNC2 gene, making them highly responsive to hunger-suppressing signals and food-related sensory cues.

Sleep Boosts Language Learning and Memory Consolidation

Learning a new language isn’t just about practice—it’s about sleep. Researchers found that sleep enhances memory of new words and grammar by synchronizing specific brainwave patterns during NREM sleep.

Depression Genes in Women Linked to Higher Heart Disease Risk

A new study analyzing genetic data from over 300,000 people revealed that women with a high genetic risk for depression also face a higher likelihood of developing heart disease, even without a depression diagnosis. This link was not observed in men, highlighting significant gender differences. Researchers emphasized the importance of addressing cardiovascular health in women, particularly those with depression, regardless of menopausal status.

Ancient Friendship: Humans and Dogs Bonded 12,000 Years Ago

Humans and canines in the Americas formed close relationships 12,000 years ago, earlier than previously thought. Archaeological findings in Alaska, including a 12,000-year-old canine tibia and an 8,100-year-old jawbone, indicate these animals relied on humans for food, such as salmon, rather than hunting independently.
