This eight-armed octopus-like pore detects taste
Cold Spring Harbor Laboratory

The neurons in our bodies are dotted with tiny pores that let essential molecules pass in and out of our cells. Neurons need these channels to send the signals that allow us to move, think, and perceive the world around us. Now, structural biologists at Cold Spring Harbor Laboratory (CSHL) have captured never-before-seen images of one of the largest pores in human neurons.
