[Sensory innervation of the brain--myth or reality?].
This paper contains a critical analysis of conceptions of the sensory innervation of the spinal cord and the brain, presented in the articles by O.S. Sotnikov (issues 2 and 3 of this journal). The criteria for identification of intracerebral primary sensory neurons are examined, as well as the possible role of neuronal cilia. The significance of asynaptic dendrites and bipolar cells is discussed. The importance of an adequate usage of some terms and the advisability of a combined morphological and physiological analysis for the study of sensory intracerebral exteroceptors is emphasized.
