INSIGHT

Mitochondria's Energy & Hormone Role

  • Mitochondria transform biochemical energy from food and oxygen into electrochemical energy powering cells.
  • They also produce hormones like cortisol and sex hormones essential for life and brain function.

Mapping Brain Mitochondria Precisely

  • The brain weighs 2% of body mass but consumes 20-25% of the body's energy, showing high energy demand.
  • Dr. Picard's team created physical small brain cubes matching MRI voxels to map mitochondria distribution and function across 700 brain areas.
INSIGHT

Brain Regions Show Mitochondrial Diversity

  • Mitochondria density varies across brain regions and cell types, specialized for energy needs.
  • Evolutionarily newer brain areas have more mitochondria specialized for energy transformation, revealing diverse mitotypes in the brain.
