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 Prize The Brain Prize The Brain Prize, formerly known as The Grete Lundbeck European Brain Research Prize, is an international scientific award honouring "one or more scientists who have distinguished themselves by an outstanding contribution to neuroscience and who are still active in research". Founded in 2011 by the Lundbeck Foundation, the prize is associated with a €1 million award to the nominees, the world’s largest brain research prize. Nominees can be of any nationality. Prize winners are expected to interact with Danish brain researchers e.g. through lectures, master classes, seminars, exchange programmes for researchers or other activities agreed with and
