Description
Achard and Bullmore examine how well human brain networks work compared with what they cost. Brain wiring is sparse yet complex, with economical small-world traits that keep signals fast without endless links. The authors used brain scans that track activity over time.
They compared functional networks in two groups of healthy older adults, weighing efficiency against connection cost. A brain that achieves high efficiency at low cost can share information widely without wasting resources. Their results help explain how ageing brains stay organised, and give a baseline for spotting costly breakdowns in disease.
