Brain Metabolism

Meaning

Brain metabolism refers to the complex biochemical processes that sustain the energy requirements and structural integrity of neural and glial cells. This critical physiological function relies predominantly on glucose as a primary fuel source to support continuous neuronal signaling and synaptic transmission. The metabolic rate of the brain is exceptionally high, demanding a constant and substantial supply of oxygen and nutrients relative to its mass. Proper hormonal regulation is integral to ensuring optimal cerebral glucose uptake and utilization.
