Résumé

Quoiqu'une inhibition récurrente se présente dans le cortex sensorimoteur du chat, il n'a pas été possible d'enregistrer l'activité unitaire des neurones intercalaires de la voie récurrente. Dans les expériences décrites ici, l'onde 2 du potentiel somatique primaire évoqué par la stimulation des fibres thalamo-corticales, montrait un accroissement marqué après stimulation conditionnante; simultanément il se produisait une inhibition des ondes tardives du potentiel. Donc l'onde 2 peut être due aux neurones intercalaires inhibiteurs activés durant la phase d'inhibition.
