Neurons – A whistle-stop Tour
... Between the axon terminal of one neuron and the dendrite is a tiny saltwater-filled gap called the synaptic cleft. The brain can transmit between 400 to 1,200 spikes per second, but cannot go at the top rate for more than a few seconds. A typical ‘spike’ requires 70 millivolts , or one-twentieth of ...
