Part 2/11:
Contrary to common assumptions that neurons primarily rely on glucose for energy, Huberman emphasizes the critical importance of fats—especially structural fats—in maintaining brain health. Neurons are encased in double-layered membranes composed of specific fats known as essential fatty acids and phospholipids. These membranes regulate neuronal electrical activity and signaling, making fats fundamental to neuron viability and efficient brain function.
