Mutation linked to autism impairs oxytocin-mediated social behavior in mice

Mutations associated with autism can inhibit the release of the bonding hormone oxytocin and cause abnormal social behavior in mice, researchers report.

Scientists map gene changes underlying brain and cognitive decline in aging

Alzheimer’s disease shares some key similarities with healthy aging, according to a new mathematical model.

Insulin is necessary for repairing olfactory neurons

Insulin plays a critical role in the maturation, after injury, of immature olfactory sensory neurons. Applying insulin into the nasal passage could be developed as a therapy for injury caused by a host of issues.

Our dreams’ weirdness might be why we have them, argues new AI-inspired theory of dreaming

Why we dream is a divisive topic within the scientific community, and the neuroscience field is saturated with hypotheses. Inspired by techniques used to train deep neural networks, a neuroscience researcher argues for a new theory of dreams: the overf…

The eyes offer a window into Alzheimer’s disease

While it has been said that the eyes are a window to the soul, a new study shows they could be a means for understanding diseases of the brain. According to new research, retinal scans can detect key changes in blood vessels that may provide an early s…

New complexity of traveling brain waves in memory circuits

Researchers have observed a new feature of neural activity in the hippocampus – the brain’s memory hub – that may explain how this vital brain region combines a diverse range of inputs into a multi-layered memories that can later be recalled.

Politically polarized brains share an intolerance of uncertainty

A new study on political polarization showed how an aversion to uncertainty is often associated with black-and-white political views.

Brain mechanism of curiosity unraveled

Researchers have discovered a new brain circuit underlying curiosity and novelty seeking behavior. Using several innovative techniques, the scientists uncovered a whole path of multiple brain regions that converts curiosity into action in mice.

Songbird neurons for advanced cognition mirror the physiology of mammalian counterparts

Neuroscientists examining genetically identified neurons in a songbird’s forebrain discovered a remarkable landscape of physiology, auditory coding and network roles that mirrored those in the brains of mammals.

New study reveals where memories of familiar places are stored in the brain

As we move through the world, what we see is seamlessly integrated with our memory of the broader spatial environment. How does the brain accomplish this feat? A new study reveals that three regions of the brain in the posterior cerebral cortex, which …
