[Neurohistologic and histochemical characteristics of Loeschke's zone of the medulla in the cat].
Neuronal organization and transmitter characteristics of chemosensitive area on the ventral medulla surface (zone L) of the cat were studied using neurohistological and histochemical methods. Neurons of different shape and size are heterogeneously distributed in zone L. They are concentrated mostly at the level of the hypoglossal nerve root, their number decreasing in the rostral and caudal directions. Negligible part of zone L neurons is choline- and monoaminergic, whereas the majority of neurons appears to release other transmitters. Cholinergic and noncholinergic cholinoceptive neurons as well as neurons sensitive to catecholamines and serotonin, are found in zone L. The conclusion is made that catecholamine-, serotonin- and cholinergic fibres found in zone L may be of local origin or run from other structures.
