Sommation spatiale

Home

Qu'est-ce que la sommation spatiale ?

La sommation spatiale correspond à l’intégration simultanée des potentiels postsynaptiques provenant de plusieurs synapses situées sur des dendrites différentes du même motoneurone.

Qu'est-ce que la sommation temporelle ?

La sommation temporelle consiste en l’intégration des potentiels postsynaptiques produits par une même synapse, mais de façon répétée et rapprochée dans le temps.

Tester différents scénarios d'activation de neurones excitateurs et inhibiteurs, et observer comment ces stimuli influencent la production d'un potentiel d'action. 1) Quelle est la différence entre les effets des neurones excitateurs et inhibiteurs ? 2) Quelles combinaisons de stimulations aboutissent à un potentiel d’action ? Pourquoi ?

Explorer l’effet de l'augmentation de la fréquence des stimulations sur la membrane postsynaptique. 3) Que se passe-t-il lorsque les stimuli sont trop espacés dans le temps ? 4) Comment la fréquence des stimulations influence-t-elle la génération d’un potentiel d’action ?

5) Comment la sommation spatiale et temporelle contribuent-elles à la décision d’un motoneurone de déclencher un potentiel d'action ?6) Pourquoi l’intégration de ces signaux est-elle cruciale pour la régulation du mouvement ?
