Using a brain-computer interface in mice, researchers found that instructive feedback signals are directed to individual neurons rather than broadcast broadly. This selective feedback allows neurons to adjust their behavior correctly for efficient learning.
The study, published in Nature, draws parallels to artificial neural networks that optimize by comparing outputs to targets and backpropagating errors. This offers insights into the biological basis of learning and could inspire improved brain-inspired AI algorithms, though widespread biological validation remains ongoing.
