[The spatial organization of the hypothalamic neurons that project into the "stomach" area of the vagosolitary complex].

Peculiarities of localisation of total population of hypothalamic neurons, associated with innervation of vagosolitary complex "stomach" area were studied using retrograde axonal transport of horseradish peroxidase. The enzyme was administered in microportions into the mentioned area of vagosolitary complex (100-150 ml of 20% enzyme solution). The labelled neurons were exposed in the hypothalamic area basically from ipsilateral side. Greatest part of these neurons was located within paraventricular nucleus and lateral hypothalamic area as two bands oriented in caudodorsal direction. These bands length varied widely in different animals (ranging from 0.5 to 0.2 mm) mainly due to their disperse caudal ends. Rostral part of these formations were more compact and were joined by a thin cross arch, consisting of bipolar labelled neurons along it. As for interaural line this arch was located in the distance within 6.75-07.05 mm in different animals.
