With a painter's sensibility, Noémie Frère reveals the intimacy of brain tissue, where each cell seems to dance in its place.the large white silhouettes, with their outstretched arms, are astrocytes, glial cells that have long remained in the shadows, but are now recognized as essential architects of the brain.
They guide neuron growth, organize connections and maintain the balance of the cerebral environment. In red, more compact, neurons project their short, dense extensions to transmit electrical signals, like a vibrating language between cells.
This image captures a moment in this silent choreography, where the precise interactions between neurons and astrocytes shape brain development. A better understanding of these exchanges means a better understanding of disorders such as autism or multiple sclerosis, where this subtle balance can be disrupted.
