![]() Large sex differences were found only in the frequency of some rare brain “types.” Last, supervised clustering algorithms revealed that the brain “type(s)” typical of one sex category in one sample could be typical of the other sex category in another sample. Unsupervised clustering algorithms revealed that common brain “types” are similarly common in females and in males and that a male and a female are almost as likely to have the same brain “type” as two females or two males are. An anomaly detection analysis showed that brains from females are almost as likely to be classified as “normal male brains,” as brains from males are, and vice versa. Here we contrasted the two hypotheses by analyzing the structure of 2176 human brains using three analytical approaches. ![]() An alternative interpretation is that the brain types typical of females are also typical of males, and sex differences exist only in the frequency of rare brain types. ![]() 7School of Mathematical Sciences, Tel Aviv University, Tel Aviv, Israelįindings of average differences between females and males in the structure of specific brain regions are often interpreted as indicating that the typical male brain is different from the typical female brain.6International Max Planck Research School NeuroCom, Leipzig, Germany.5Faculty of Life Sciences, University Leipzig, Leipzig, Germany.4Max Planck Research Group for Neuroanatomy and Connectivity, Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany.3School of Computer Science, Tel Aviv University, Tel Aviv, Israel.2Sagol School of Neuroscience, Tel Aviv University, Tel Aviv, Israel.1School of Psychological Sciences, Tel Aviv University, Tel Aviv, Israel.It is the hypothetical source of/evidence for its existence is provided by: Sanskrit vartate "turns round, rolls " Avestan varet- "to turn " Hittite hurki- "wheel " Greek rhatane "stirrer, ladle " Latin vertere (frequentative versare) "to turn, turn back, be turned convert, transform, translate be changed," versus "turned toward or against " Old Church Slavonic vrŭteti "to turn, roll," Russian vreteno "spindle, distaff " Lithuanian verčiu, versti "to turn " German werden, Old English weorðan "to become " Old English -weard "toward," originally "turned toward," weorthan "to befall," wyrd "fate, destiny," literally "what befalls one " Welsh gwerthyd "spindle, distaff " Old Irish frith "against.Daphna Joel 1,2*, Ariel Persico 3, Moshe Salhov 3, Zohar Berman 2, Sabine Oligschläger 4,5,6, Isaac Meilijson 7 and Amir Averbuch 3 It forms all or part of: adverse anniversary avert awry controversy converge converse (adj.)
