The nervous system is an extremely complex communication system that can send and receive large amounts of information simultaneously. The nervous system has two distinct parts: the central nervous system (the brain and the spinal cord) and the peripheral nervous system (the nerves located outside the brain and spinal cord). The main unit of the nervous system is neural cells (neurons). The rou...

We here present an image from the rare original slides from Camillo Golgi (Figure 1), which are kept at the Golgi Museum and at the Museum for the History of the University of Pavia (Pavia, Italy). Camillo Golgi (1843 – 1926), Professor of General Pathology and Histology at the University of Pavia, provided seminal scientific contributions, including in 1898 the discovery of the cell organelle ...

post-traumatic stress disorder (ptsd) is an anxiety disorder that can typically occur after traumatic events in which the individual felt sever helplessness or horror. ptsd has a lifetime prevalence of 5–8% and women show higher prevalence than in compared with men. neuroinflammation is associated to anxiety and related disorders such as ptsd. it is an early, specialized immune reaction fallowi...

When silver nitrate is administered to rats in their drinking water for many months, they develop a generalized argyria. In the central nervous system, the deposition of silver follows the pattern of the so called hematoencephalic barrier (Wislocki and Leduc, (2); Dempsey and Wislocki, (3)). The present observations concern the deposition of silver in the rat's eye, investigated by both light m...

A comparison has been made between the chaetotaxy of the gyrodactylid monogeneans Macrogyrodactylus clarii Gussev, 1961 and M. congolensis (Prudhoe, 1957) Yamaguti, 1963 from the gills and skin, respectively, of the catfish Clarias gariepinus (Burchell) from the river Nile in Egypt. Bilaterally arranged argentophilic structures on the surface of these parasites are presumed to be sensilla and a...

Dopamine (3, 4-dihydroxyphenyl ethylamine, DA) is one of the most important neurotransmitters in the mammalian central nervous system. This paper presents a new approach to detect dopamine using an electrochemical sensor based on a composite made out of chitosan-stabilized silver nanoparticles and p-toluene sulfonic acid-doped ultrathin polypyrrole film, which exploits the synergy between the c...
