Revealing the neuronal pathways involved in adaptive decision-making in primates

Neuronal pathways originating from the orbitofrontal cortex (OFC) of the brain participate in different adaptive behaviors, but which pathways are used for distinct adaptive strategies remains unclear. In a recent study, researchers from Japan conducte…

Walking in lockstep

Walking in lockstep

Researchers studied the neurological control applied to human walking that maintains the correct relationship between the leg positions. They found that the rhythm of each leg continues independently unless they become too far out of phase. This work c…

Adhesive cortical device enables artifact-free neuromodulation for closed-loop epilepsy treatment

Researchers have developed a groundbreaking soft cortical device that could revolutionize the treatment of epilepsy and other neurological disorders.

Activity in brain system that controls eye movements highlights importance of spatial thinking

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research shows that this part of th…

Higher levels of leptin indicate brain protection against late-life dementia

A study more closely links obesity to dementia, finding that leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults.

When serotonin dims the light

Signals in our brain are not always processed in the same way: certain receptors modulate these mechanisms, influencing our mood, perception, and behavior in various ways. One of these is the 5-HT2A receptor, which has a recently discovered unique char…

Penny for your thoughts? Master copper regulator discovery may offer Alzheimer’s clues

A study using a tiny roundworm could pave the way for new treatments for neurodegenerative disorders. Researchers linked the worm gene swip-10 to copper regulation — a vital element for brain health found in everyday items like wiring and cookware. Un…

Understanding changes in pre-clinical Alzheimer’s disease

A new study provides important insight into how amyloid-beta and tau proteins impact brain activity and possibly contribute to cognitive decline in Alzheimer’s disease.

Genetic risk-factor overlap between Alzheimer’s disease, and all-cause and vascular dementias

Medical researchers conducted the largest-ever genome-wide association study of all-cause dementia, finding substantial genetic overlap with vascular dementia.

Brain divides meal into different phases

The process of food intake appears to be organized at the cellular level like a relay race: during eating, the baton is passed between different teams of neurons until we have consumed the appropriate amount of energy. Through this complex mechanism, t…
