This study describes for the first time the distribution of the calcium-binding protein calretinin (CR) in the anterior thalamic nuclei (ATN) of the guinea pig during development. Brains from animals ranging from 40th embryonic day (E40) to 80th postnatal day (P80) were used in the study. No CR-immunoreactive (CR-ir) perikarya were present among the ATN at(More)
Our recent studies have shown that the distribution of calretinin (CR) in the anterior thalamic nuclei (ATN) changes significantly during the development of the guinea pig. The present study was designed to reveal the distribution pattern of calcium-binding proteins, i.e. calbindin (CB) and parvalbumin (PV), as well as the colocalization pattern of all(More)
The study describes for the first time the colocalization pattern of calbindin (CB) and cocaine- and amphetamine-regulated transcript (CART) in the mammillary body (MB) and anterior thalamic nuclei (ATN) - structures connected in a topographically organized manner by the mammillothalamic tract (mtt). Immunohistochemical study was performed on fetal (E40,(More)
The present study examines the response of colon-projecting neurons localized in the inferior mesenteric ganglia (IMG) to axotomy in the pig animal model. In all animals (n = 8), a median laparotomy was performed under anesthesia and the retrograde tracer Fast Blue was injected into the descending colon wall. In experimental animals (n = 4), the descending(More)
The caudate nucleus and the putamen of bison bonasus have been investigated. The Golgi procedure and Nissl stain had been used to reveal their cellular organization. In the Golgi preparation striatal neurons belong to the two fairly divergent main groups in which several types of cells can be distinguished. The first class, comprising the bulk of neuronal(More)
In regio supraoptica there are nucleus paraventricularis, nucleus supraopticus, area hypothalamica anterior and nucleus suprachiasmaticus. These centers are more developed in hedgehog than in mole and common shrew. Area preoptica is divided into 4 parts (medial, lateral, periventricular and middle) from among the middle part in hedgehog is less developed(More)
The characteristic features of the common shrew amygdala (CA), as shown by volumetric comparisons of the individual nuclei, are the poor development of the lateral (LA) and basomedial (BM) nuclei as well as the particularly strong formation of the basolateral (BL) and lateral olfactory tract (NLOT) nuclei. The central (CE), cortical (CO) and medial (ME)(More)
On the basis of Golgi and Klüver-Barrera preparations we have distinguished four types of neurons in the dorsal lateral geniculate nucleus of the guinea pig: 1. Fusiform neurons with 1-3 thick dendritic trunks arising from each pole of the soma. The dendritic trunks branch twice dichotomically. The branches sometimes show varicosities. 2. Pear-shaped cells.(More)
A subpopulation of the pig inferior mesenteric ganglia (IMG) neurons projecting to the colon exhibit calbindin-like immunoreactivity. It is not known if there are any changes in the chemical coding patterns of these neurons during porcine proliferative enteropathy (PE). To answer this question, juvenile Large White Polish pigs with clinically diagnosed(More)
The studies were carried out on the mesencephalons of 4 European bison Preparations were made by means of Golgi impregnation and Klüver-Barrera method. Three types of neurons were distinguished in the red nucleus: 1. Large multipolar (perikaryons 70-105 microns) with 6-8 dendritic trunks which bifurcate twice and next give thin collaterals. 2. Small(More)
