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

Magneto…nope!

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!
