10Minute Neuroscience Synapses

In this video, I cover the different components of a synapse, including the presynaptic neuron, postsynaptic neuron, synaptic cleft, and synaptic vesicles. I discuss how signals are propagated at chemical synapses through the use of neurotransmitters, as well as how neurotransmitters are removed from the synaptic cleft by enzymes and/or reuptake. I also cover the components and function of electrical synapses. • Key points: • 00:00 General introduction to synapses • 1:23 Different components of a chemical synapse • 4:28 Termination of synaptic transmission (e.g., enzymes, reuptake) • 6:55 Electrical synapses • REFERENCES: • Purves D, Augustine GJ, Fitzpatrick D, Hall WC, Lamantia AS, Mooney RD, Platt ML, White LE, eds. 2018.
