oxygen in the brain
utilisation of glucose
synthesis of neurotransmitters

17% decrease in prefrontal cortex neural volume between 20 and 80 years
high level of aerobic fitness may help age related reductions in blood flow and neural volumes
leading to higher cognitive function
evidence from high altitude studies - reduced O2 showed reduction in cognitive performance
