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.

Specific neurobiological link identified between hearing loss and cognitive decline

Presbycusis is a prevalent form of age-related hearing loss that also hinders speech recognition. While scientists have linked hearing loss to an increased risk of cognitive decline, the biological "bridge" between the two has remained unclear.

Senescent astrocytes identified as key drivers of Alzheimer's progression

Researchers from the NeuroAD group (Neuropathology of Alzheimer's Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA-BIONAND Platform and CIBERNED, have made a pioneering breakthrough in the fight against this disease by identifying astrocytes as a promising cellular target for the development of future therapies.

Probiotic form matters for memory, mood, and more

How you take probiotics can affect their impact on the brain. A study from örebro University points to new possibilities for personalized approaches, depending on whether the primary aim is, for example, to improve memory or reduce depression.

Advanced use of MRI aids in accurate identification of rare, atypical parkinsonian disorders

An international study led by researchers from the Sant Pau Research Institute (IR Sant Pau) shows that advanced use of magnetic resonance imaging (MRI) allows much more accurate identification of patients with progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD).

ARVCF gene deletion leads to abnormalities in reward behavior

The ventral tegmental area (VTA) is a key brain region for dopamine production and the regulation of reward-related behaviors.

Parkinson's-related weight loss reflects a failure of the body's energy-producing pathways

Weight loss is a well-recognized but poorly understood non-motor feature of Parkinson's disease (PD). Many patients progressively lose weight as the disease advances, often alongside worsening motor symptoms and quality of life.

Causal gene mapping identifies key drivers of Alzheimer's disease progression

Researchers led by Min Zhang and Dabao Zhang of the University of California, Irvine's Joe C. Wen School of Population & Public Health have created the most detailed maps to date showing how genes causally regulate one another across different types of brain cells affected by Alzheimer's disease.

Exercise-induced activation of neurons mediates improvements in endurance

Exercise does more than strengthen muscles; it also rewires the brain. In a study publishing February 12 in the Cell Press journal Neuron, researchers reveal that the lasting gain in endurance from repeated exercise-such as the ability to run farther and faster over time-involves changes in brain activity that help muscles and hearts to become stronger.

How psychedelics alter perception: A glimpse into the brain's inner world

Research findings reinforce new approaches in psychology, using psychedelic substances under medical supervision to treat certain clinical conditions.

Ozempic users continue treatment when weight loss works despite side effects

A study on Ozempic for weight loss reveals user satisfaction is driven by efficacy, despite common gastrointestinal side effects impacting treatment adherence.

Study reveals dynamic nature of myelin swellings

An international research team of Amsterdam UMC, VU LaserLab, the Netherlands Institute for Neuroscience and the University of Edinburgh have gained new insights into the dynamics of myelin swellings in the brain.

Distinct microbial signature identified in pediatric Crohn's disease

NYU researchers have found a "microbial signature" of pediatric Crohn's disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn's patients harboring more pro-inflammatory bacteria and less protective bacteria.

AI system controls brain circuits during social behavior

A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song.

Novel DAMP markers advance myocardial contusion detection

Researchers are exploring a new generation of biochemical markers that may help clinicians detect myocardial contusion. A frequently overlooked form of heart injury caused by blunt chest trauma, earlier and more accurately.

Brain circuit links past experiences to appetite control

Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate contextual information into appetite control.

Gene activity pattern links childhood abuse to depression

Scientists have identified a pattern of gene activity present in some female survivors of childhood abuse that is associated with an elevated risk of depression.

Early cognitive stimulation preserves memory in Alzheimer’s

A team from the Institute of Neurosciences of the University of Barcelona (UBneuro) has discovered that early and sustained cognitive stimulation can help preserve brain connectivity and memory in Alzheimer's disease, even in advanced stages of the pathology.
