Alteraciones morfofuncionales en el bulbo olfatorio tras privación de estímulos olorosos (I). Estudio morfológico / Morphofunctional disorders in olfactory bulb after privation of odoriferous stimuli (I). Morphological study

Estudiamos la plasticidad del sistema nervioso analizando la repercusión macro y microscópica que sobre el bulbo olfatorio del jerbo (Meriones Unguiculatus) tiene la privación de estímulos olorosos en los primeros días tras el nacimiento. Esta privación sensorial de estímulos reduce el tamaño del bulbo en el lado tratado y altera los volúmenes de algunas de las capas bulbares. Ello indica que el desarrollo estructural del sistema nervioso precisa de una integridad de sus aferencias sensoriales (AU)

We study the olfactory bulb plasticity by olfactory deprivation in the jerbil (Meriones Unguiculatus). We analyze what effects has the odorous stimuli privation in the first days after the birth on the olfactory bulb. We have found that this stimuli absence reduces the size of the bulb in the discussed side and alters the volumes of some of the bulbars layers. This indicates that the structural development of the nervous system specifies of an integrity of their sensorial afferencies (AU)

By histochemical and immunohistochemical methods we study the effects that has the odorous stimuli privation in the first day after the birth on the activity of the olfactory bulb of the gerbil (Meriones Unguiculatus). This sensory deprivation of stimuli causes drastic reductions in given activities (Tyrosine Hydroxylase) no altering other (DOPA-Decarboxylase). This indicates that the functional ripeness of given enzymatic systems specify of an integrity of their sensorial afferences, while it is not necessary for the normal activity of other enzymes even within the same cell.
