Brain size area in women, corresponding to spatial versus language specializations. Small studies have attempted to link brain volume with functional measures such as P300 auditory evoked potentials but finding no association. Studies attempting to related sibling differences in IQ to differences in brain volume are hampered by relatively small sample sizes and the noisy nature of such difference scores, yielding weak evidence for cross-trait cross-sib correlations. The largest brain is that of the sperm whale, weighing about , and killer whales, weighing about . An elephant's brain weighs just over and a bottlenose dolphin's . Brain size tends to vary according
The Brain from Planet Arous brain-shaped creature named Gor (Dale Tate) arrives on Earth and possesses young scientist Steve March (Agar). Gor then proceeds to use his vast, destructive powers to bend the planet to his will, threatening to wipe out the capital city of any nation that dares to defy him.
