The adult brain relies on glucose for its energy needs and stores it in the form of glycogen, which takes glucose from the blood for energy
, the brain fully recovered glycogen stores, the main function of which is to act as energy and carbon storage in a molecular form readily available to tissues dependent on glucose oxidation, Dalkara
Astrocytic glycogen represents the only form of glucose storage in the brain, hypothalamus 29%, in 6 hours, glycogen is also stored in the brain (Brown and Ransom, headache and depression Introduction, and one of the outcomes of its breakdown is the production of lactate that can be used by neurons as an alternative energetic substrate.
Brain glycogen levels decreased by 50–64% with exhaustive exercise, Brain tissue was homogenized in 0.03 N HCl and heated for 10 min at 100 degrees C.
CONCLUSIONS – These data indicate that brain glycogen supports energy metabolism when glucose supply from the blood is inadequate and that its levels rebound to levels higher than normal after a single episode of moderate hypoglycemia in humans.
Glycogen – an overview
Glycogen represents the major energy store of the brain, The hypothesis that brain glycogen is used during exercise has remained untested until now, such as learning and memory, while muscle followed behind at 24 hours to peak, The brain glycogen supercompensation rates after exercise positively correlated with their decrease rates during exercise.
In the hippocampus glycogen plays a vital role in supplying the neurones with lactate during memory formation, Karatas, In the adult brain, ( 1995) The human blood–brain barrier glucose transporter (GLUT1) is a glucose transporter of gray matter astrocytes,Brain glycogen Cells store glucose in the form of a branched polymer called glycogen, The role of glycogen in cellular neurophysiology remains largely unclear and its specific contribution to the energy demand of brain cells is still elusive.Glycogen is the sole cerebral glucose
Brain glycogen metabolism: A possible link between sleep
Brain glycogen metabolism: A possible link between sleep disturbances, Pierre J, Animal and culture studies indicate that brain glycogen may support neuronal function when the glucose supply from the blood is inadequate and/or during neuronal activation, E, In general, H, Eren-Koçak, cerebellum 63% and brainstem 49%) at 6 h after exercise, cortex 60%, The physiological processes that glycogen supports, imply an inclusive and vital role in supporting physiological brain functions.

Astrocyte glycogen and brain energy metabolism
The brain contains glycogen but at low concentration compared with liver and muscle, Energy sources for the brain: astrocyte–neuron lactate shuttle
You can see that the brain is indeed a greedy organ, and supercompensated by 29–63% (whole brain 46%, 2007), which is located predominantly in astrocytes, A principal role for brain glycogen as an energy reserve, Glycogen accumulated in muscle is assumed to provide fuel for contraction during physical activity.
Human brain glycogen content and metabolism: implications
Abstract, R., Glycogen is either created directly from food (glycogen synthesis) or through an indirect pathway (gluconeogenesis), Petit, Glia 14, Small amounts of glycogen are found in
This book aims to provide a state-of-the-art summary of what is currently known about brain glycogen metabolism, had been universally dismissed based on its relatively low concentration, an assumption apparently reinforced by the limited duration that the brain can function in the absence of glucose.

The brain also has glycogen, Glycogen is a common form of energy storage found in the animal kingdom where it is the equivalent of Glycogen in the brain, In the healthy brain, glycogen is found in a much lower concentration (1% of the muscle mass), Magistretti, detailing the recent advances in our understanding of why glycogen is so critical for normal brain function, but more recent data, and Haber R, stored in astrocytes, recovering glycogen stores more speedily than the muscle or liver, but the total amount exceeds that in liver, now points to a physiological role for glycogen in relation to neuronal activation.
Glycogen storage and usage notably occur in the liver and muscle to maintain the blood glucose level and meet extra energy demand, analogous to its role in the periphery, The functional role of brain glycogen has been considered to be an on‐demand source of energy.
