Effect of temperature and glia in brain size enlargement and origin of allometric body-brain size scaling in vertebrates [PDF]

open access: yes, 2014
Background: Brain signaling requires energy. The cost of maintaining and supporting energetically demanding neurons is the key constraint on brain size.

Homeostasis of carbohydrates and reactive oxygen species is critically changed in the brain of middle-aged mice: Molecular mechanisms and functional reasons

open access: yesBBA Advances, 2023
The brain is an organ that consumes a lot of energy. In the brain, energy is required for synaptic transmission, numerous biosynthetic processes and axonal transport in neurons, and for many supportive functions of glial cells.

A model of brain circulation and metabolism: NIRS signal changes during physiological challenges [PDF]

open access: yes, 2008
We construct a model of brain circulation and energy metabolism. The model is designed to explain experimental data and predict the response of the circulation and metabolism to a variety of stimuli, in particular, changes in arterial blood pressure, CO2

Association between cognitive performance and cortical glucose metabolism in patients with mild Alzheimer's disease [PDF]

open access: yes, 2005
Background: Neuronal and synaptic function in Alzheimer's disease (AD) is measured in vivo by glucose metabolism using positron emission tomography (PET). Objective: We hypothesized that neuronal activation as measured by PET is a more sensitive index of

Resolvin D1 reprograms energy metabolism to promote microglia to phagocytize neutrophils after ischemic stroke

open access: yesCell Reports, 2023
Summary: Neutrophil aggregation and clearance are important factors affecting neuroinflammatory injury during acute ischemic stroke. Emerging evidence suggests that energy metabolism is essential for microglial functions, especially microglial ...

Multivitamins and minerals modulate whole-body energy metabolism and cerebral blood-flow during cognitive task performance: a double-blind, randomised, placebo-controlled trial [PDF]

open access: yes, 2016
Background: The brain is by far the most metabolically active organ in the body, with overall energy expenditure and local blood-supply closely related to neural activity.

Creatine protects against excitoxicity in an in vitro model of neurodegeneration. [PDF]

open access: yes, 2012
Creatine has been shown to be neuroprotective in aging, neurodegenerative conditions and brain injury. As a common molecular background, oxidative stress and disturbed cellular energy homeostasis are key aspects in these conditions. Moreover, in a recent

Brief exposure of neuronal cells to levels of SCFAs observed in human systemic circulation impair lipid metabolism resulting in apoptosis

open access: yesScientific Reports, 2022
Communication between gut microbiota and the brain is an enigma. Alterations in the gut microbial community affects enteric metabolite levels, such as short chain fatty acids (SCFAs). SCFAs have been proposed as a possible mechanism through which the gut
