A first-of-its-kind trial has pitted a common antidepressant against psilocybin, the psychedelic compound found in magic mushrooms. The results are mixed but suggest the drug is at least as effective as common antidepressants in treating depression.

Scientists at the University of Tokyo have come up with novel approach to tackling brain plaques associated with Alzheimer's, clearing them through the use of injectable, oxygenated atoms that are activated by infrared light.

A new study has revealed that a human scream can convey a complex range of emotions beyond fear and danger. What's more, our brains perceive and respond to them in different and somewhat counter-intuitive ways.

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.
