Immune cells sculpt circuits in the brain

Immune cells play an unexpected role in fine-tuning the brain's neural circuits, according to research published in September, 2020 in Neuron. The immune cells that reside there, known as microglia, not only protect the brain ...

Before eyes open, they get ready to see

A KAIST research team's computational simulations demonstrated that the waves of spontaneous neural activity in the retinas of still-closed eyes in mammals develop long-range horizontal connections in the visual cortex during ...
