This figure is a 3D computer reconstruction of 3 excitatory neurons (blue neurons), called pyramidal neurons in the Neocortex together with a single inhibitory neurons (white) called a small basket cell. The neurons were captured in an experiment that revealed how the small inhibitory neuron sends information to the 3 excitatory neurons in order to control their activity. The control of excitability in the brain is important for normal information processing and also to prevent hyperexcitable states such as epilepsy.
