Lactate's behavioral switch in the brain: an in-silico model

Author(s): Soltanzadeh M; Blanchard S; Soucy JP; Benali H;

It is well known that glucose serves as the main energy substrate for the brain, and emerging evidence emphasizes its involvement in both physiological processes and disease (traumatic brain injury, memory, epilepsy, etc.). Furthermore, the usefulness of ma ...
