      GABA release by hippocampal astrocytes 

      Le Meur, Karim; Mendizabal Zubiaga, Juan Luis ORCID; Grandes Moreno, Pedro Rolando ORCID; Audinat, Etienne (Frontiers Res Found, 2012-08-17)
      Astrocytes can directly influence neuronal activity through the release of various transmitters acting on membrane receptors expressed by neurons. However, in contrast to glutamate and ATP for instance, the release of GABA ...

      Metabolic efficiency with fast spiking in the squid axon 

      Moujahid, Abdelmalik ORCID; D'Anjou, Alicia (Frontiers, 2012-11-15)
      Fundamentally, action potentials in the squid axon are consequence of the entrance of sodium ions during the depolarization of the rising phase of the spike mediated by the outflow of potassium ions during the hyperpolarization ...

      Neuronal Hyperactivity Disturbs ATP Microgradients, Impairs Microglial Motility, and Reduces Phagocytic Receptor Expression Triggering Apoptosis/Microglial Phagocytosis Uncoupling 

      Abiega Etxabe, Oihane; Beccari Galeano, Marlene Soledad; Diaz-Aparicio, Irune; Nadjar, Agnes; Layé, Sophie; Leyrolle, Quentin; Gómez-Nicola, Diego; Domercq García, María ORCID; Pérez-Samartín, Alberto; Sánchez-Zafra, Víctor; Paris Guerrero, Ignacio; Valero Gómez-Lobo, Jorge; Savage, Julie C.; Hui, Chin-Wai; Tremblay, Marie-Ève; Deudero, Juan J. P.; Brewster, Amy L.; Anderson, Anne E.; Zaldumbide Dueñas, Laura; Galbarriatu, Lara; Marinas, Ainhoa; Vivanco Ruiz, María del Mar; Matute Almau, Carlos José; Maletic-Savatic, Mirjana; Encinas Pérez, Juan Manuel; Sierra Saavedra, Amanda (2016)
      Phagocytosis by microglia is tightly coupled to apoptosis, swiftly removing apoptotic cells and actively maintaining tissue homeostasis, but the neuronal hyperactivity associated with epilepsy disrupts the ATP gradients ...
