Planum temporale "non-human primate language area" for? Planum temporale The planum temporale is the cortical area just posterior to the auditory cortex (Heschl's gyrus) within the Sylvian fissure. It is a triangular region which forms the heart of Wernicke's area, one of the most important functional areas for language. Original studies on this area found that the planum temporale was one of the most asymmetric regions in the brain, with this area being up to ten times larger in the left cerebral hemisphere than the right. The planum temporale makes up the superior surface of the superior temporal gyrus to the parietal
Red Hills Fissure Pleistocene. The abundant fossil remains of the Jamaican Coney ("Geocapromys brownii") found there have enabled the construction of a life table for that species. Analysis of fluorine uptake in the fossil bone has allowed the time-span of the deposit to be dated to about 25–40 thousand years ago. Fossil remains of the extinct Jamaican flightless ibis ("Xenicibis xympithecus") have also been found there. Red Hills Fissure Red Hills Fissure is a palaeontological site at the Red Hills in Saint Andrew Parish of south-eastern Jamaica. The Red Hills Fissure is a karstic solutional feature, with a vertical extent of about 8
