A new study has investigated how BPA and BPS plasticizers impact nerve cells in the adult brain, with the authors finding that they can permanently disrupt signal transmission, and also interfere with neural circuits involved in perception.

A new study has found a strong relationship between bacterial imbalances in the oral microbiome and a key biomarker of Alzheimer’s. This new research focuses on the link between amyloid levels and different oral bacteria species in healthy older adults.

Scientists may have identified three new subtypes of multiple sclerosis. Analyzing thousands of MRI scans, AI algorithms uncovered patterns regarding which areas of the brain are affected first, which could lead to more focused treatment options.

Researchers are closer to an objective blood test for mood disorders, with a new study describing a panel of blood-based biomarkers that can distinguish between depression and bipolar disorder, and measure the future risk of developing these conditions.

More than one in 10 adults suffer from chronic rhinosinusitis, an inflammatory sinus condition. A new brain imaging study suggests the disease is linked with functional brain connectivity changes that could explain cognitive problems such as brain fog.

A new implantable "brain glue" material could offer a way to intervene in the sequence of events following a traumatic brain injury, by mimicking the supporting structure of brain cells to prevent tissue loss and regenerate neurons.

Although cochlear implants do allow some deaf people to hear again, adjusting the devices to individual users can be challenging. An experimental new implant is designed to help in that regard, by reading the user's brain waves.

A new article is reporting promising results from a Phase 1 human trial testing a vaccine designed to help a patient's immune system better target brain tumors. The data suggests the vaccine is safe and stimulates a significant immune response.

Australian paleontologists have examined the brain cases of extinct flightless birds in the dromornithidae family – including some of the largest birds that ever existed – and found that they represented some weird evolutionary experiments.

A striking new study has found gene expression can dramatically increase in some brain cells hours after a person dies. The researchers suggest scientists studying post-mortem brain tissue must take into account these significant changes in future work.

For some people a small irritation can wreck their day, while others can shake off minor problems and move on. A new study is suggesting persistent activity in the amygdala could be why some are unable to move on from momentary negative experiences.

A landmark proof-of-concept study reveals a novel brain-machine interface using ultrasound tracking brain activity to predict subsequent motor movements. The preliminary research suggests a non-invasive way of controlling computers with one's mind.
