Ever wondered how the brain reshapes itself in response to sensory experiences like vision, movement, and hearing? A study conducted by researchers from the Allen Institute for Brain Science (USA), published in the journal Nature, utilized the BARseq method to map millions of neurons in nine rat brains.

In just three weeks, scientists identified over 9 million cells, unveiling that each brain region possesses a unique “signature,” determined by the specific combination of neuron types.

Researchers observed significant cell reorganization within the visual cortex of visually deprived rats, altering distinctions with adjacent areas. These findings extend beyond vision to other cortical areas, underscoring the crucial role of sensory experiences in sculpting the brain.
