Metabolic Substrate for Neurons

Meaning

Metabolic Substrate for Neurons refers to the essential energy-yielding molecules—primarily glucose and, under certain conditions, ketone bodies—that the brain utilizes to fuel its extremely high and continuous metabolic rate, sustaining uninterrupted neuronal activity. The consistent and efficient supply of this substrate is absolutely non-negotiable for maintaining cognitive function, as the brain lacks significant endogenous energy reserves. Fluctuations in substrate availability directly impair neurotransmission and compromise cognitive performance.
