Research Abstract |
In developing nervous system, unnecessary synapses are eliminated. In the present study, the timing for glial coverage of small cell soma appears to be consistent with the decrease of axosomatic synapses on the small cells. Axosomatic synapses remained in adult stages under pharmacological inhibition of astrocytic processes extension during neonatal stages. These observations indicats that astrocytes could participate actively in regulating the decrease of axosomatic synapses on small cells in the caudal nucleus tractus solitarius during postnatal development.
