Lateral ventricles ( VL ; Vesalius, 1543 ) : The part of the ventricles (Hippocrates) in the right and left endbrain (Kuhlenbeck, 1927); they communicate with the unitary third ventricle (Galen, c173) through the interventricular foramina (one for each lateral ventricle). They correspond to the first and second ventricles, were known in macrodissected adult humans to Erasistratus (c310-c250 BC; see Clarke & O'Malley, 1996, p. 12), and were named such by Vesalius (1543; see translation by Singer, 1952, pp. 41, 68).
