INTRODUCTION: The mammillary body is a part of so-called extended hippocampal system and its importance for memory is well known. Our previous study has revealed that pharmacological inactivation of the medial mammillary nucleus (MM) attenuates theta rhythm activity in the hippocampus (HP) in urethane-anesthetized rats. In this study, we examined the involvement of GABAergic transmission in the MM...
This study describes the distribution of galanin (Gal) and galanin receptor 2 (GalR2) in the pre‐optic area (POA) of the female guinea pig. Frozen sections were undergone for a routine immunofluorescence labelling. Gal and GalR2 display immunoreactivity in all parts of the pre‐optic area. Gal shows reactivity both in perikarya and fibres, whereas GalR2 was observed only in perikarya. Gal‐ and GalR2‐immunoreactive...
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, E50, E60), newborn (P0) and postnatal (P20,...
Unbiased stereological methods were used to examine and compare morphometrically the geniculate bodies (GB) in representatives of four mammalian orders (Insectivora, Rodentia, Lagomorpha, and Carnivora). The significant disproportion was observed between the relative sizes of both geniculate nuclei and their neuronal populations in the common shrew and the bank vole. The medial geniculate body (MGB)...
The aim of the study was to describe the distribution of cocaine and amphetamine-regulated transcript (CART) and calcium binding proteins (CaBPs) of EF-hand family, namely calbindin, calretinin, and parvalbumin in the preoptic area (POA) of the ram. Frozen sections were processed for a routine immunofluorescence labelling. CART, calbindin, and calretinin immunoreactivity was present in neurons and...
