L'échelle mésoscopique est une échelle intermédiaire entre l'échelle microscopique, qui caractérise les atomes ou les molécules, et l'échelle macroscopique.
Cerebral temperature, what else ?
 
Temperature has profound effects on a wide range of parameters of neural activity at various scales.
 
At the cell level, ionic currents, membrane potential, input resistance, action potential amplitude, duration and propagation, and synaptic transmission have all been shown to be affected by temperature variations.
 
At mesoscopic scales of neural activity, temperature changes can steer network activity toward different functional regimes, affecting the duration, frequency and firing rate of activated states during slow frequency oscillations, and the ability to end these states.
 
Temperature also has a substantial effect on chemical reaction rates, and affects the blood oxygen saturation level by changing haemoglobin affinity for oxygen. Furthermore, cooling reduces metabolic processes, and has been used to silence cortical areas to study their function.

Impact sur la physiologie cérébrale des variations de la température cérébrale
 
Les variations de la température cérébrale a d'importants effets sur une large gamme de paramètres de l'activité neuronale à différentes échelles.
 
Au niveau cellulaire, les courants ioniques, le potentiel membranaire (pompe Na/K) l'amplitude du potentiel d'action, la durée et la propagation et la transmission synaptique sont tous affectés par les variations de température.
 
A des échelles mésoscopiques de l'activité neuronale, les changements de température modifient l'activité fonctionnelle des réseaux neuronaux, affectant la durée, la fréquence et l'état d'activation, en particulier des ondes lentes à l'ECG.
 
La température a également un effet important sur le nombre de réaction chimique au sein du neurone et de la glie, et affecte le niveau de saturation du sang en oxygène en modifiant l'affinité de l'hémoglobine pour l'oxygène. En outre, le refroidissement réduit les processus métaboliques, et a été utilisé pour réduire l'activité d'aires corticales afin d'étudier leurs fonctions.
