Web20 jul. 2024 · Ion channels are essential for transmitting signals in the nervous system and brain. One large group of ion channels includes members that are activated by cyclic nucleotides, small molecules used to transmit signals within cells. These cyclic nucleotide-gated channels play an important role in regulating our ability to see and smell. Web23 mrt. 2015 · Charvy Narain. 23 Mar 2015. The electrical impulse that powers the workings of the brain and the heart begins with charged particles passing through cellular structures known as ion channels. Using the same technique used to decode the structure of DNA, an Oxford University team has been able to catch snapshots of an ion channel in action.
