The human brain is made up of 80-100 billion number of cells called neurons, each of which makes connections to 1000 other cells making a total of 100 trillion connections in the brain. These junctions are called synapses and are the means by which signals are transmitted throughout the brain. In these synapses, receptors are optimally positioned to receive a signal by scaffolding molecules, which dock the receptors.. The Selvin lab is interested in this molecular organization of the synapse and the mechanisms behind how these synapses “learn” and “forget”. To do this we use the super resolution methods PALM and STORM.
