Needle-thin brain implant enables recording and targeted drug delivery

A new type of brain implant may have implications for both brain research and future treatments of neurological diseases such as epilepsy.

Optogenetic tool helps decipher mechanisms of brain dysfunction in Huntington’s disease

Synaptic plasticity — the brain's ability to modify the connections between neurons to support learning — is one of the neural functions profoundly altered in Huntington's disease, with a direct impact on brain function.

Novel wireless device uses light to send information directly to the brain

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain - bypassing the body's natural sensory pathways.

How immune signals activate brain circuits to drive sickness-induced social withdrawal

MIT researchers have discovered how an immune system molecule triggers neurons in a specific brain circuit to shut down social behavior in mice modeling infection.

Brain circuit identified as key to repetitive and compulsive behaviors in mice

Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviors in mice, even when natural rewards such as food or social contact are available.

Study uncovers role of mechanical forces in human gastrulation

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

Study reveals how neural excitability and learning potential fluctuate across the day

Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our commute to work, what we feel - and whether it leaves a lasting impression - depends on our internal state at that moment.

PRIME fiber-optic device can manipulate neural activity deep in the brain

Fiber-optic technology revolutionized the telecommunications industry and may soon do the same for brain research.

Systematic analysis reveals psilocybin's impact on obsessive-compulsive behaviors

A systematic review published today in Psychedelics by Mr. James Gattuso and colleagues at the Florey Institute of Neuroscience and Mental Health synthesizes clinical and preclinical evidence on psilocybin's effects on obsessive-compulsive behaviors, revealing consistent therapeutic potential across human patients and validated animal models.

Optogenetics and artificial intelligence open path to personalized Parkinson’s treatment

Globally recognized figures like Muhammad Ali and Michael J. Fox have long suffered from Parkinson's disease. The disease presents a complex set of motor symptoms, including tremors, rigidity, bradykinesia, and postural instability.

Study reveals how a key spinal circuit shapes the choreography of sex

For decades, it was thought that while the brain orchestrated male sexual behaviour – arousal, courtship, and copulation – the spinal cord merely executed the final act: ejaculation.

New research links postictal symptoms in epilepsy to hidden brain waves

In everyday clinical practice, symptoms are regularly observed after epileptic seizures, known as "post-ictal symptoms", which, in contrast to the usually short duration of seizures, typically last several minutes to hours. Besides symptoms such as impaired speech and language comprehension, a state of disorientation may occur.

Researchers identify seizure-associated depolarization as cause of post-ictal symptoms

People with temporal lobe epilepsy in particular often wander around aimlessly and unconsciously after a seizure. Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Neurodegenerative Diseases (DZNE) have identified a neurobiological mechanism that could be responsible for this so-called post-ictal wandering and potentially other postictal symptoms.

Scientists discover IC–encoder neurons that shape visual perception

An illusion is when we see and perceive an object that doesn't match the sensory input that reaches our eyes. In the case of the image below, the sensory input is four Pac Man–like black figures.

Scientists uncover brain circuit that turns cravings into eating behavior

Researchers found that the bed nucleus of the stria terminalis integrates pleasure signals from central amygdala prodynorphin neurons and hunger signals from agouti-related peptide neurons to drive consumption. Manipulating this bed nucleus of the stria terminalis circuit bidirectionally altered food intake and body weight in mice.

New swallowable device enables noninvasive gut nerve stimulation

Scientists have long struggled with how to study the gut's vast nervous system - often called the body's 'second brain' - without damaging it.
