Time course of the calcium concentration in \ 
the dendrite of a CAl hippocampal pyramidal 
neuron in response to synaptic stimulation as a 
function of time, running horizontally. The 
concentration along the dendrite, running ver- 
tically, is shown in false color, with the resting 
level in blue and the highest concentration in 
red.
