p.762 left column top paragraph:"The relative energy consumption of the brain has increased particularly during the evolution of humans from lower primates (Mink et al., 1981 Aiello and Wheeler, 1995), reflecting a 3-fold expansion in the size of the brain relative to the body and an increase in the number of synapses per cortical neuron (primary source). This greater energy allocation to CNS tissue over millions of years underpins our brains’ greater cognitive powers, and was made possible by an increased and higher-quality food intake, along with less energy expenditure on the gut and locomotion (Aiello and Wheeler, 1995 Navarrete et al., 2011)." |
