Localized proton NMR spectroscopy was used to study cerebral metabolism in the visual cortex of healthy adults during rest and photic stimulation. Basal lactate levels showed considerable interindividual differences ranging from below detectability (mM) to about 1 mM without consistent alterations during photic stimulation. Local brain glucose levels were significantly reduced (≈ 50%) during the entire period of photic stimulation and recovered to resting levels (≈0.8 mM)within 10 minafter the… 
Dynamic MR imaging of human brain oxygenation during rest and photic stimulation
TLDR
Dynamic FLASH (fast low‐angle shot) magnetic resonance (MR) imaging was used to monitor changes in brain oxygenation in the human visual cortex during photic stimulation, and a decrease in the basal MR signal in the calcarine cortex was observed, which may be understood as an autoregulatory adaptation to increased overall brain activity associated with information processing due to continuous perception of visual stimuli.
Limits on activation‐induced temperature and metabolic changes in the human primary visual cortex
TLDR
Limits on Lac concentration changes were too weak to constrain theories of the metabolic use of elevated Glc consumption during stimulation, and emphasize the challenges of measuring even large Lac changes accompanying stimulation.
Time-Related Increase of Oxygen Utilization in Continuously Activated Human Visual Cortex
TLDR
It is suggested that in the activated brain, the increased energy demands initially are not fully met with oxidative metabolism and must predominantly be supported by increased glycolysis and with continued activation, oxygen utilization increases reducing the need for excess glyCOlysis.
Visual Activation in α‐Chloralose‐anaesthetized Cats Does Not Cause Lactate Accumulation in the Visual Cortex as Detected by [1HINMR Difference Spectroscopy
TLDR
The present data show that neuronal activation to this degree in the cat brain is not associated with aerobic lactate production to an extent that can be detected with 1H MRS.
Net increase of lactate and glutamate concentration in activated human visual cortex detected with magnetic resonance spectroscopy at 7 tesla
TLDR
Functional magnetic resonance spectroscopy measurements at 7 Tesla confirm that lactate and glutamate changes during physiological stimulation are small (i.e. below 20%) and shows that the increased sensitivity allows reproduction of previous results with fewer subjects.
Visual stimulation, 1H MR spectroscopy and fMRI of the human visual pathways
TLDR
Functional MRI was used to confirm the presence of activity in the visual cortex during the visual stimulation and any signal observed near the 1.33 ppm resonance frequency of the lactate methyl-group was artifactual, originating from lipid signals from outside the volume of interest (VOI).
Dynamic Relationship Between Neurostimulation and N-Acetylaspartate Metabolism in the Human Visual Cortex
TLDR
It is concluded that the NAA metabolic cycle in the visual cortex is intimately linked to rates of neuronal signaling, and that the functional cycle of NAA is associated with its release to ECF, thus supporting the hypothesis that an important function of the N AA metabolic cycle is that of an efflux MWP.
Brain lactate responses during visual stimulation in fasting and hyperglycemic subjects : A 1 . 5 Tesla 1 H-MRS study
TLDR
The results of this preliminary study demonstrate a method for observing a consistent activity-stimulated increase in brain lactate at 1.5 Tesla and show that variations in blood glucose across the normal range have little effect on this response.

Lactate rise detected by 1H NMR in human visual cortex during physiologic stimulation.
TLDR
Brain lactate concentration is detected during physiologic photic stimulation in human visual cortex with results consistent with a transient excess of glycolysis over respiration in the visual cortex, occurring as a normal response to stimulation in the physiologic range.

TLDR
Functional activation of the intact chloralose-anesthetized rat is associated with the stimulation of “aerobic” glycolysis but does not result in disturbances of energy or acid-base homeostasis, suggesting that the postischemic generation of evoked potentials does not require measurable amounts of energy.
Visually evoked dynamic blood flow response of the human cerebral circulation.
TLDR
The dynamics of the metabolic mechanism that regulates cerebral blood flow was studied in 10 normal human subjects using a noninvasive transcranial ultrasonic Doppler method, suggesting the mechanism of very fast metabolic regulation of cerebralBlood flow in humans.
Nonoxidative glucose consumption during focal physiologic neural activity.
TLDR
Transient increases in neural activity cause a tissue uptake of glucose in excess of that consumed by oxidative metabolism, acutely consume much less energy than previously believed, and regulate local blood flow for purposes other than oxidative metabolism.
Cerebral glucose is detectable by localized proton NMR spectroscopy in normal rat brain in Vivo
TLDR
The observed level of cerebral glucose in fasted rats covered a range of 15–4096 of that of NAA giving absolute concentrations of 1.1–2.1 mM, and the arterial blood glucose concentration was 7.7 ± 0.8 mM in the same group of animals.
What the clinician can learn from MRS lactate measurements
TLDR
Early data on elevation of lactate in human visual cortex by physiologic stimulation and turnover of pathologically elevated brain lactate pools in animals and humans suggest that the new methods are likely to benefit clinical practice both directly–by providing information useful in management of individual patients–and indirectly–through improved understanding of disease processes.

TLDR
Measurement of lactate transport rate constants in normal rats and rats treated with kainic acid supports the hypothesis that radiolabel derived from glucose can leave the brain asRadiolabeled lactate in conditions in which intracerebral lactate concentration rises, and indicates that blood–brain transfer of lactates can be significant.
