Cover picture: Double-label immunohistochemistry of an identified local circuit connection between a presynaptic pyramidal neuron (black), loaded with biocytin and reacted with NI-DAB, and its postsynaptic interneuronal target, a medium arbor basket neuron (brown) filled with Lucifer yellow and developed with DAB. The axon of the pyramidal cell could be followed to the dendrite of the nonpyramidal cell which was characterized in terms of its membrane properties and responsivity to excitatory input. For details, see the article by Krimer and Goldman-Rakic in this issue (pages 3788-3796).
