Electrically coupled cells make a connection

Inside our brains are billions of neurons, which communicate to each other via chemical messengers called neurotransmitters.  Neurotransmitters are released from one cell and bind to receptors on a neighbor cell, creating a chemical synapse between the two neurons.  Precise connections between neurons create microcircuits made up of multiple cells, which are responsible for processing … Continue reading Electrically coupled cells make a connection


We have all heard about birds being able to sense the Earth’s magnetic field in order to navigate during migration, but how can they do that?  There have been a number of studies that implicated iron-rich cells in the upper beak of birds as magnetoreceptors.  Just like there are neurons that can sense mechanical stimuli, … Continue reading Magneto…nope!
