WebJul 16, 2024 · A lot of work has been done on how neurons spread electrical signals to each other through synapses — the nanoscale electrochemical connection points between neurons. It is the brain’s circuitry of some 100 trillion of these synapses that permit us to imagine, sense, retain information and progress. There are two fundamentally different types of synapses: In a chemical synapse, electrical activity in the presynaptic neuron is converted (via the activation of voltage-gated calcium channels) into the release of a chemical called a neurotransmitter that binds to receptors located in the … See more In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
