The Science Of Mood, Mitochondria, and Brain Energy w/ Siobhan Mitchell
The Joe Cohen Show
The Brain's Energy Consumption and Emotional Control
The brain is the most energy-intensive organ in the body, using about 20% of the body's oxygen despite being only 5% of the body weight. Depletion of energy leads to decreased efficiency of mitochondria, affecting overall brain function. The frontal cortex, responsible for controlling emotions and understanding reality, requires significant energy to maintain control over the brain. The amygdala, responsible for fear and anxiety, needs constant control through GABA inhibition. When the brain experiences energy depletion, the amygdala becomes overactive, leading to increased fear and anxiety. Furthermore, the brain can create storytelling scenarios when the amygdala becomes excessively active due to energy problems, even when the individual is not engaged in any activity.
