Simplified brain slice glucose utilization.
Brain slice glucose utilization (SGU) can be measured by methods analogous to those used for in vivo cerebral glucose utilization. In order to make this technique more accessible and applicable to a broad range of experimental conditions, we have derived a simplified operational rate equation and generated the table of apparent rate coefficients necessary to apply the equation under different e...
متن کاملDynamic functional imaging of brain glucose utilization using fPET-FDG
Glucose is the principal source of energy for the brain and yet the dynamic response of glucose utilization to changes in brain activity is still not fully understood. Positron emission tomography (PET) allows quantitative measurement of glucose metabolism using 2-[(18)F]-fluorodeoxyglucose (FDG). However, FDG PET in its current form provides an integral (or average) of glucose consumption over...
متن کاملAstrocytes Couple Synaptic Activity to Glucose Utilization in the Brain.
Astrocytes have functional characteristics that make them particularly well suited to couple glutamate uptake from the synaptic cleft to Na(+)-K(+)-ATPase activation and glucose utilization. The changes in glucose metabolism associated with these processes may provide signals detected by positron emission tomography.
متن کاملChanges in local cerebral glucose utilization during rewarding brain stimulation.
The quantitative 2-deoxy[14C]glucose method was used to determine local cerebral glucose utilization in unrestrained rats responding (lever-press) for rewarding electrical stimulation to area A10 (ventral tegmental area) and in similarly implanted inactive controls. Self-stimulation was associated with significant increases in metabolic activity, highly circumscribed in the ventral tegmental ar...
متن کاملBrain slice chamber
The Neurolog system has been designed by Digitimer for optional instrumentation flexibility when processing electrophysiological signals. The system is modular with more than 50 types of interchangeable modules on offer for signal conditioning, amplification, tinting, averaging, integration and so on. Only those modules required to perform a particular function need to be inserted into the comm...
