Puberty is the final stage of maturation of the hypothalamo-pituitary-gonadal axis and is characterized by changes in circulating gonadotropins and increased levels of sex steroids. There are both genetic and external factors (e.g. nutrition, stress) which can alter the onset of puberty. The aim of this study was to determine the onset of puberty in genetically homogeneous inbred mouse strains. Five strains were used: 129X1/SvJ, DBA/2J, C57BL/6J, CBA/CaJ and A/J. Various puber...

Recent studies using the viral transneuronal tracing technique allowed to reveal brain neurons synaptically connected with the adrenal gland, via specific infections within functionally related chains of neurons. The aim of the present study was to investigate whether cerebral neurons involved in the innervation of the adrenal gland exhibit asymmetry or not. In order to label simultaneously the supraspinal neurons connected with the right- and left-sided adrenal glands, dual-v...
