The rostral region of vertebrate neural tubes develops into three morphologically distinct swellings or the primary brain vesicles by differential proliferation of neuroepithelial territories: the forebrain, midbrain, and hind brain (Ishikawa et al., 2012), each of brain vesicles may be composed of several smaller repetitive units known as neuromeres (Nieuwenhuys, 1998).

MUNICH, Germany, December 19, 2018 -- In mammals, generation of new neurons (neurogenesis) is mainly limited to early childhood and occurs in adulthood only in a few regions of the forebrain.

([5]) Although learning and memory have considered as complex cognitive processes and multiple mechanisms are involved in cognition, extensive research has established the relationship between cognitive impairment and the cholinergic system in the basal forebrain. ([6]) The aim of this study was to develop a model of renovascular hypertension by using Goldblatt's two kidneys one clip (2K1C) method and evaluating the levels of choline acetyltransferase (ChAT) mRNA as the main marker of cholinergic system activity as well as ACE mRNA level in the frontal cortex.
