A neurobiologist investigated the transmission speed of nerve impulses across synapses in the mammalian nervous system. They measured the synaptic delay (the time taken for a neurotransmitter to diffuse across the synaptic cleft and initiate an action potential in the postsynaptic neuron) across six different synapses.
