|All Things Big and Small: The Brain's Discerning Taste for Size|

The human brain can recognize thousands of different objects, but neuroscientists have long grappled with how the brain organizes object representation; in other words, how the brain perceives and identifies different objects. Now researchers at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and the MIT Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size, with a specific region of the brain reserved for recognizing large objects and another reserved for small objects.
Their findings, to be published in the June 21 issue of Neuron, could have major implications for fields like robotics, and could lead to a greater understanding of how the brain organizes and maps information.
"Prior to this study, nobody had looked at whether the size of an object was an important factor in the brain's ability to recognize it," said Aude Oliva, an associate professor in the MIT Department of Brain and Cognitive Sciences and senior author of the study.
