Histology and Histochemistry of the Adrenal Gland African Giant Rat (Cricetomys gambianus, Waterhouse)
Provedor de dados: 77
Autores: Olukole,Samuel Gbadebo; Adeagbo,Mojibola Abosede; Oke,Bankole Olusiji.
The histology and histochemistry of the adrenal gland of the African giant rat, AGR (Cricetomys gambianus Waterhouse) was carried out using ten adult male rats with the knowledge of providing information which could be helpful in an improved knowledge of the structure and function of the gland. The adrenal gland of the African giant rat has a distinct cortex and medulla surrounded by a thin rim of capsule. The adrenal cortex has three zones which are basically the zona glomerulosa, zona fasiculata and zona reticularis with the absence of zona intermedia. The zona glomerulosa contains polyhedral cells which form irregular clusters or cords while the zona fasiculata had radial cells of cuboidal or polyhedral shape. The cells of zona reticularis are similar...

Ovary plays the vital role in the reproductive biology and biotechnology of female animals. With the aim to study the ovarian morphometry of Black Bengal goat, both right and left ovaries were collected from the slaughter houses of different Thanas under Mymensingh district. For each of the specimens, gross parameters such as weight, length and width were recorded. Then they were processed and stained with H &amp;amp; E for histomorphometry. Our study revealed that the right ovary (0.53±0.02 g) was heavier than the left (0.52±0.02 g). The length of the right ovary (1.26±0.04 cm) was lower than the left (1.28±0.02 cm) but the width of the right (0.94±0.02 cm) was greater than the left (0.90±0.03 cm). The diameter of ovarian follicles in the cortex was...

Modulation of post-coital dopaminergic tone by prior parity
Provedor de dados: 52
Autores: Sider,Lucia Helena; Hucke,Erica Engelberg Teixeira da Silva; Felicio,Luciano Freitas.
The aim of this study was to investigate the possible effects of reproductive experience on dopaminergic profile in three different brain tissues, hypothalamus, striatum and cortex in rats on 7th-8th day of pregnancy during the light-dark shift (between 1700-1900h). Results showed that in hypothalamus, dopamine levels increased and DOPAC/DA decreased as a function of parity. In cortex, no differences were observed. In striata, the haloperidol-induced HVA and HVA/DA increases were less intense in experienced animals. These findings suggested that reproductive experience produced functional central changes during pregnancy, with different neurochemical responses depending on the brain region.

The brain decade in debate: I. Neurobiology of learning and memory
Provedor de dados: 56
Autores: Baddeley,A.; Bueno,O; Cahill,L.; Fuster,J.M.; Izquierdo,I.; McGaugh,J.L.; Morris,R.G.M.; Nadel,L.; Routtenberg,A.; Xavier,G.; Da Cunha,C.
This article is a transcription of an electronic symposium in which some active researchers were invited by the Brazilian Society for Neuroscience and Behavior (SBNeC) to discuss the last decade's advances in neurobiology of learning and memory. The way different parts of the brain are recruited during the storage of different kinds of memory (e.g., short-term vs long-term memory, declarative vs procedural memory) and even the property of these divisions were discussed. It was pointed out that the brain does not really store memories, but stores traces of information that are later used to create memories, not always expressing a completely veridical picture of the past experienced reality. To perform this process different parts of the brain act as...

The brain decade in debate: VI. Sensory and motor maps: dynamics and plasticity
Provedor de dados: 56
Autores: Das,A.; Franca,J.G.; Gattass,R.; Kaas,J.H.; Nicolelis,M.A.L.; Timo-Iaria,C.; Vargas,C.D.; Weinberger,N.M.; Volchan,E.
This article is an edited transcription of a virtual symposium promoted by the Brazilian Society of Neuroscience and Behavior (SBNeC). Although the dynamics of sensory and motor representations have been one of the most studied features of the central nervous system, the actual mechanisms of brain plasticity that underlie the dynamic nature of sensory and motor maps are not entirely unraveled. Our discussion began with the notion that the processing of sensory information depends on many different cortical areas. Some of them are arranged topographically and others have non-topographic (analytical) properties. Besides a sensory component, every cortical area has an efferent output that can be mapped and can influence motor behavior. Although new behaviors...
