[Circadian development of synaptic ribbons in the hair cells of the internal ear. Morphometric and statistical analysis].

We have realized a morphometric and statistic study about "synaptic ribbons" in the hair cells of the Corti organ. These structures are pinealocyte features with remarkable and demonstrated circadian circle and also the main parameter to measure the pineal function. Therefore we tried to clarify if the hair cells are or not resembling to other cellular types with the functional circadian circles, as well as if they present it or not in their basic function , as they are also included in the "endocrine diffuse system" and "the paraneuron" concepts.
