Scientists discover spiral-shaped signals that organize brain activity

Scientists have discovered human brain signals traveling across the outer layer of neural tissue that naturally arrange themselves to resemble swirling spirals.

Astrocyte processing of serotonin regulates olfactory perception

Researchers have uncovered novel aspects of astrocyte function in olfactory, or smell, perception revealing changes in their gene expression patterns that turn these brain cells into a hub of olfactory sensation processing.

Illusions are in the eye, not the mind

Numerous visual illusions are caused by limits in the way our eyes and visual neurones work — rather than more complex psychological processes, new research shows.

Pregnancy hormone repairs myelin damage in MS mouse model

A new study has identified a treatment that could repair myelin in the cortex, undoing some of the damage caused by MS.

New discovery can help detect brain tumors

Folate-based radiopharmaceuticals can be used in positron emission tomography (PET) imaging to detect folate receptors in brain tumours. The discovery of folate receptors and their exploitation potential with respect to brain tumours is a new and signi…

Video games spark exciting new frontier in neuroscience

Researchers have used an algorithm from a video game to gain insights into the behavior of molecules within live brain cells. Researchers used coding tools to build an algorithm that is now used by several labs to gather rich data about brain cell acti…

AI helps show how the brain’s fluids flow

A new, AI-based technique for measuring fluid flow in the brain could lead to treatments for diseases such as Alzheimer’s.

Psychedelic drugs reopen ‘critical periods’ for social learning

Neuroscientists have long searched for ways to reopen ‘critical periods’ in the brain, when mammals are more sensitive to signals from their surroundings that can influence periods of brain development. Now, researchers say a new study in mice shows th…

Biodegradable ultrasound opens the blood-brain barrier

A new, biodegradable ultrasound far more powerful than previous devices could make brain cancers more treatable, researchers report.

New images capture unseen details of the synapse

Scientists have created one of the most detailed 3D images of the synapse, the important juncture where neurons communicate with each other through an exchange of chemical signals. These nanometer scale models will help scientists better understand an…
