How your brain communicates through electrical and chemical signals
In short: This video explores the intricate mechanics of synapses, the vital connections in your nervous system. You will learn how signals jump between neurons using both electrical currents and chemical messengers, and discover how substances like cocaine disrupt this delicate process.
The video examines the distinction between electrical and chemical synapses. It details how electrical synapses utilize gap junctions to transmit signals, while chemical synapses rely on the release of neurotransmitters to bridge the gap between neurons.
By understanding these mechanisms, we gain insight into the fundamental ways the nervous system facilitates communication and how external substances can interfere with these essential biological pathways.
