In neuroscience, the term neuromyth refers m & eacute;todosto an unsubstantiated misconception which has been generated a number of reasons, such as a misunderstanding or misquotation n & uacute;meroof scientific facts regarding the nervous system. This study m & eacute;todosaddresses the persistence of neuromyths related to the number neurons in the human brain, especially in educational neuroscience texts. Through a review of 24 texts in neuroscience and related totalfields, as well as a systematic search of experimental articles in Web of Science database, the figures reported in the literature compared with experimental data obtained through stereology. enmost recent experimental results suggest that the human sistemacontains approximately 19 billion neurons, in contrast to commonly cited inaccurate figures, such as 86 billion, 100 billion, araone billion and 86 trillion, which could originate from incorrect lastranslations and terminological misunderstandings. The results psiqui & aacute;tricas, show the need to demystify these neuromyths and promote further enexperimental research that allows more precise estimates 2017),neuronal quantification, thus contributing to a better understanding probablementeofthe human brain in various areas of neuroscience.
