We saw that a couple of dendrites, maybe that one and that one and that one, might get excited or triggered. And when we say it gets triggered, we're saying that some type of channel gets opened. That's probably the trigger.

"WebTransmitting Along Neurones. When a nerve cell is not stimulated, it is in a resting state. During this state, the inside of the axon is relatively more negative than outside of the axon, this is called the resting potential. The reason behind this negative charge is because of the distribution of the principal ions (Na+ and K+). " - How is a nervous impulse transmitted

WebWhere Nerve Impulses Are Passed from Neuron to Neuron A synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Neurons are cells that transmit information between your brain and other parts of the central nervous system. WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal.
