Function of Spindle Neurons
Spindle neurons are relatively enormous cells that may allow rapid communication across the relatively large brains of great apes, Elephantidaes, and Cetacea. Spindle neurons have been implicated by scientists as having an important role in many cognitive abilities and disabilities generally unique to humans, ranging from savant perceptiveness and perfect pitch to dyslexia and autism. While rare in comparison to other neurons, spindle neurons are abundant, and large, in humans. However, the concentration of spindle cells has been measured to be three times higher in Cetaceans in comparison to humans. They have only been found thus far in the anterior cingulate cortex (ACC), fronto-insular cortex (FI), and the dorsolateral prefrontal cortex.

Famous quotes containing the words function of and/or function:
“The more books we read, the clearer it becomes that the true function of a writer is to produce a masterpiece and that no other task is of any consequence.”
—Cyril Connolly (1903–1974)
“If the children and youth of a nation are afforded opportunity to develop their capacities to the fullest, if they are given the knowledge to understand the world and the wisdom to change it, then the prospects for the future are bright. In contrast, a society which neglects its children, however well it may function in other respects, risks eventual disorganization and demise.”
—Urie Bronfenbrenner (b. 1917)
