Alcmaeon made observations about seeing, hearing, tasting, and smelling and distinguished perception from understanding. was young in the old age of Pythagoras). All his doctrines which have come down to us relate to physics or medicine; and seem to have arisen partly out of the speculations of the Ionian School, with which rather than the Pythagorean, Aristotle appears to connect Alcmaeon, partly from the traditional lore of the earliest medical science.[19]. Alcmaeon of Croton Distinguished veins from arteries Period: 500 to Dec 31, 1300. Finally, Alcmaeon about the phenomenon of death advances a double explanation, both physically Sleep is produced by pretreatment of blood from the veins and philosophically Humans die for this because they cannot https://www.britannica.com/biography/Alcmaeon-Greek-philosopher-and-physiologist, Stanford Encyclopedia of Philosophy - Alcmaeon. 754. philosopher-scientist.

In fact, through his philosophical, medical school, he proposes a proper physical activity, balanced diet and recreation through music and reading. Censorinus, a Roman grammarian, which refers to Alcmaeon about the explanation for determining the gender difference of the unborn reiterates the equality between male and female seed: the sex of the unborn depends on who has been received seed more abundant, if the father is born male, if the mother is born female [21], [16]. Based on this observation, and more rudimentary, Alcmaeon described the senses, except for the touch sense. and arteries, as some have claimed.
