In noisy settings, participants struggled more to hear faint sounds with their eyes closed, while matching visuals made it easier. Researchers found that shutting the eyes leads the brain to over-filter incoming sounds. Keeping your eyes open may actually improve how well you hear in noise.

Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways linked to depression and other brain disorders but appear to cause far fewer psychedelic-like effects.

Smell, touch, sound, sight, and balance constantly influence one another, shaping how food tastes, objects feel, and even how heavy our bodies seem. Scientists now believe humans may have more than 20 distinct senses working at once. Everyday illusions and experiences reveal just how surprisingly complex perception really is.

Normally, the brain predicts the sound of its own inner speech and tones down its response. But in people hearing voices, brain activity ramps up instead, as if the voice belongs to someone else. The discovery could help scientists develop early warning signs for psychosis.

At UCSF, neuroscientist Jennifer Mitchell is testing a pharmaceutical form of LSD called MM120, which has shown striking results in reducing symptoms by promoting neuroplasticity and easing rigid thought patterns. In clinical trials, a single dose significantly outperformed standard treatments, offering hope to those who have found little relief elsewhere.

Scientists in China have developed a promising early screening method that detects Parkinson s from subtle changes in the scent of ear wax yes, really. By analyzing specific volatile compounds in ear wax and feeding that data into an AI-powered olfactory system, they achieved 94% accuracy in identifying who had the disease. If expanded successfully, this low-cost, non-invasive technique could transform early detection and treatment of this debilitating neurological disorder.

New research shows that patients who were sedentary for more than 14 hours a day in the month after leaving the hospital had a sharply higher chance of suffering another heart problem or even dying within a year. But there’s good news: simply replacing 30 minutes of sitting with light activities like walking around the house—or even more sleep—cut risks dramatically, in some cases by more than half.

These implants may one day benefit people who can't receive a cochlear implant, such as those with Neurofibromatosis type 2 (NF2) and other severe inner ear abnormalities. In a new preclinical study, researchers report on benefits in large animal models, and based on the results, hope for future trials in humans.

Until now, there has been no objective way to measure tinnitus severity and clinicians rely on patient survey questionnaires. The researchers plan to use these biomarkers to develop and test new therapies that can reduce or eliminate the phantom sounds (i.e. ringing in the ears) caused by tinnitus.

Humans' spatial acuity is high in front of our faces but decreases around the sides of our head, and the researchers' experiments obtained very similar results from listeners in the AudioDome, proving that the loudspeaker array can reproduce sound locations at a spatial scale beyond the human limits of perception.

Now imagine what it must be like for the employees. In a new study, researchers found that when background music at a workplace is out of sync with what workers need to do their jobs, it can affect their energy, mood -- and even performance.

Even a single minute of stimulation with a unique sound, called 'sound spice ,' reduced the staggering and discomfort felt by people that were asked to read a document in a moving vehicle. Their findings suggest a simple and effective way to alleviate this common disorder.

Researchers focused on a group of interacting genes called the Hippo pathway, which serve as a 'stop growing' signal that the lab has shown to inhibit cell proliferation in the ear during embryonic development. The scientists demonstrated that the Hippo pathway also suppresses the regeneration of damaged sensory receptors in the ear and eye of adult mice.

For decades, researchers have known that these gating springs must exist, but they could not find them. A team has now discovered just such a spring for the first time. Their findings shed new light on our understanding of the sense of hearing and the function of ion channels.

But most people who endure these experiences during childhood and adolescence prove to be resilient to these mental health effects. A new study finds that when this adversity occurs during brain development may affect how susceptible people are to anxiety and other psychiatric problems as adults. According to the study experiencing low-to-moderate levels of adversity during middle childhood (between the ages of 6 and 12) and adolescence may foster resilience to anxiety later in life.

The procedure, called CALEC (cultivated autologous limbal epithelial cells) involves taking stem cells from a healthy eye, expanding it into a graft over several weeks, then transplanting it into a patient's damaged eye. The groundbreaking procedure was developed to help people with injuries like chemical burns that lead to irreversible limbal stem cell deficiency, and the researchers hope the new findings warrant additional trials.

By applying existing mathematical models to a generic mock-up of a cochlea -- a spiral-shaped organ in the inner ear -- the researchers revealed a new layer of cochlear complexity. The findings offer fresh insight into the remarkable capacity and accuracy of human hearing.

The brain uses this information, along with inputs from the eyes and joints, to maintain the body's balance. Visual information has long been proven to affect balance -- for example, strobe lights and swirling images can cause instability -- but a new study shows that sounds can also be a disruptive factor for those who have vestibular hypofunction, a vestibular system disorder resulting in impaired balance.

The findings could guide future efforts to stimulate the regeneration of sensory hearing cells in patients with hearing loss and balance disorders. The study focuses on two cell types in the inner ear: the sensory cells that detect sound, and the supporting cells that create an environment where sensory cells can thrive. In highly regenerative species such as fish and lizards, supporting cells can also transform into replacement sensory cells after injury -- a capacity absent in humans, mice and all other mammals.

The answer involves two baby chickens and a mirror.

Magicians have long captivated audiences with visual tricks, such as pulling a bunny from a hat or sawing someone in half, but tricks that rely on sound are scarce. A new article explores why creating a magical experience using only sound may be challenging and underscores the importance of making magic accessible to people with blindness.

Higher levels of noise were associated with disturbed sleep quality measured by activity monitors. Noise had little impact on sleep duration but higher likelihood of reporting sleeplessness.

One of these is the 5-HT2A receptor, which has a recently discovered unique characteristic: it dampens incoming visual information, giving our brain more space for internal processes and interpretations. This discovery could also help explain the effects of drugs like LSD. When this receptor is overactivated, external sensory input is suppressed, and the brain generates more internally-driven images.

The findings support that metals in the body are associated with the progression of plaque buildup in the arteries and potentially provide a new strategy for managing and preventing atherosclerosis.
