Background: Brain cells were shown to rely on two energy subtrates to sustain their activity: glucose and lactate. Each of these substrates are taken up by brain cells via specific transporters and metabolized in classical biochemical pathways. The critical question remains: Between metabolism and transport, what is the limiting step for the utilization of each energy substrate under resting vs. activated condition?
Goal: The goal of the project is to determine whether transport of the main energy substrates for the brain, glucose and lactate, can become rate-limiting following an increase in cerebral activity.
Mathematical tools: The student will learn to use a mathematical software (Matlab) in order to conduct simulations from a given set of parameters and equations derived from Michaelis-Menten kinetics.
Biological or Medical aspects: The “biology supervisor” will provide background of the main aspects related to brain energy metabolism and Michaelis-Menten kinetics.
Supervisors: Luc Pellerin & Aitana Morton de Lachapelle
