A recurring theme is the role of inactivating potassium channels in regulating performance. Although different aspects of cnidarian behaviour are controlled by separate neuronal systems...

... that this similarity extended to the ORs, which were originally annotated as GPCRs. Surprisingly,recent evidence shows that insect ORs can act like ligand-gated ion channels,either completely or partially bypassing the amplification steps connected to the activation of G proteins. Although the involvement of G...

.... A substantial proportion of neuronal energy consumption is related to the movements of ions across the neuronal cell membrane through ion channels, though other processes such as vesicle loading and transmitter recycling also consume energy. Many of the energetic costs within neurons are linked to 3Na + /2K...
