WebJan 17, 2024 · These neurons pass information from one end of their “body” to the other as a tiny electrical signal. But one cell doesn’t actually touch another, and the signals can’t jump across the tiny spaces in between. To cross those tiny gaps, called synapses, they rely on chemical messengers. These chemicals are known as neurotransmitters. WebA single neuron may contain more than one type of potassium channel. The best-known flow of K + is the outward current following depolarization of the membrane. This occurs through the delayed rectifier channel (I DR), which, activated by the influx of Na +, counteracts the effect of that cation by allowing the discharge of K +. granby land trust
