SciNaPPS Seminar: The Carbon Footprint of the Resting Human Brain
11 May 2012
SciNaPPS - Science, Neurology, and Psychiatry/Psychology Seminars - presents this free seminar on the carbon footprint of the resting human brain at the Brain and Mind Research Institute.
Presented by Professor D. S. Fahmeed Hyder, from Biomedical Engineering and Diagnostic Radiology at Yale University in the US.
The term 'carbon footprint' is shorthand for the brain's incessant appetite for carbon-derived energy via glucose oxidation to support neuronal firing at nerve terminals.
Regional variability of resting energy is examined in cortical grey matter with PET data of glucose oxidation rates in normal awake humans. Uniformly high oxidative demand in the awake human brain supports widespread cortical signaling of resting-state networks, which when globally disrupted results in ubiquitous metabolic reduction.
This designation of fMRI-based networks requiring globally high metabolic demand differs from previous descriptions that focus on small regional differences.
Time: 3.30pm - 4.30pm
Location: Level 5 Lecture Theatre, 94 Mallet St, Camperdown.
