Calbindin D-28K is found in 30% of neurons in spinal dorsal laminae I and II.
Calbindin does not associate with specific electrophysiological phenotype.
Calbindin may associate with putative excitatory neurons and is found in some radial, vertical and central neurons.
Calbindin containing neurons receive relatively weak excitatory synaptic drive.
Altered synaptic drive to calbindin neurons does not contribute to central sensitization in neuropathic pain.
