Triple fluorescent labeled section; Purkinje neurons are labeled green, the glia are labeled blue and cell nuclei are labeled red.  Purkinje neurons (branching cells in the cortex) are some of the largest and most complex cells in the mammalian brain, possessing diameters almost as large as a human hair. Each of the cells exhibits an abundance of very active dendrites and is capable of receiving input from over 200,000 other cells. Confocal 2-photon microscopy. X380 at 10 cm wide)
