The Brain's Precision in Detecting Small Quantities
A recent study conducted by the University of Tübingen, University of Bonn, and University Hospital Bonn has shed light on how our brains perceive different quantities of objects. The research reveals that our brains employ two distinct mechanisms for number processing: "subitizing" for quick and accurate perception of smaller numbers (four and under), and a less precise estimation method for larger numbers (five and above). Neurons dedicated to smaller numbers are more selective and precise, inhibiting nearby neurons to reduce error, a mechanism not present for larger numbers. This research could potentially contribute to a better understanding of developmental disorders like dyscalculia.
