The bony-eared assfish has the smallest known brain–body mass ratio of all vertebrates [3] Brain size usually increases with body size in animals (i.e. large animals usually have larger brains than smaller animals); [4] the relationship is not, however, linear. Small mammals such as mice may have a brain/body ratio similar to humans, while ...
Mice have a direct brain/body size ratio similar to humans (1/40), while elephants have a comparatively small brain/body size (1/560), despite being quite intelligent animals. [18] Treeshrews have a brain/body mass ratio of (1/10). [19] Several reasons for this trend are possible, one of which is that neural cells have a relative constant size ...
Brain size tends to vary according to body size. The relationship is not proportional, though: the brain-to-body mass ratio varies. The largest ratio found is in the shrew. [57] Averaging brain weight across all orders of mammals, it follows a power law, with an exponent of about 0.75. [58]
Fixed the body weight key to reflect the correct unit of measurement (it was in kilograms instead of grams). This will now reflect the source for the graphic. 08:48, 31 July 2014
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...

In the years to follow, body composition scans became popular due to their ability to better measure overall health than BMI does. An InBody 570, like the one I tried, can cost up to $15,000.
The unusual high brain energy consumption percentage of mormyrinae fish is thus due to them having the unusual combination of a large brain in a low energy consuming body. [1] The actual energy consumption per unit mass of its brain is not in fact particularly high and indeed lower (2.02 mg g 1 h 1 ) than that in some other fish such as ...
