“…Sensitive and sympathetic innervation of internal organs in postnatal development and under experimental influence was investigated in the works of Valentin V. Shilkin , Valentina V. Porseva (Porseva et al, 2017), Andrey Emanuilov et al (2008), Petr M. Masliukov . Petr Masliukov, a former PhD student of Nozdrachev, carried out a comprehensive study of the patterns of age‐related changes in the innervation of internal organs; he described in detail the morphological, neurochemical and functional characteristics of the neurons of the ANS in postnatal ontogenesis (Masliukov, 2001; Masliukov et al, 2000a, 2000b, 2016). Nozdrachev and Masliukov obtained new data on the age‐related characteristics of neuropeptide regulation of internal organs in postnatal ontogenesis, in particular, the role of neuropeptide Y in the ANS (Nozdrachev & Masliukov, 2011).…”
