WebSynapses Where two neurons meet there is a small gap called a synapse . An electrical impulse cannot directly cross the gap so a different mechanism has to be used. WebConduction of nerve impulse occurs due to the presence of active and electronic potentials along the conductors. Transmission of signals internally between the cells is achieved through a synapse. Nerve conductors comprise relatively higher membrane resistance and low axial resistance. The electrical synapse has its application in escape ...

"WebElectrical synapses thus work by allowing ionic current to flow passively through the gap junction pores from one neuron to another. The usual source of this current is the potential difference generated locally by the action potential (see Chapter 3). The “upstream” neuron, which is the source of current, is called the presynaptic element, and the “downstream” … " - How are impulses transmitted at synapses gcse
