Big brains are not necessarily synonymous with intelligence

Many people often think that 'big brain is smart', but the latest study by scientists from Queen Mary Academy, University of London (UK) has rejected that idea.

Research shows that insects can perform some clever movements that previous studies suggest that only large animals can do. For example, bees can classify, count, explain the similarities and differences of similar things, and can distinguish symmetrical and asymmetrical forms.

Professor Kars of Queen Mary Academy's Psychological Research Center has not yet found that a brain with a large volume can complete a more complex function.

It is like a computer, it can have very large hardware, but does not mean that it has a good processor. Thus, very few neurons can also complete 'advanced' functions.

Experimental results on computer models have found that only a few hundred nerve cells are needed to perform the calculation function.

Scientists hope, this study can help find clever ways as well as effective measures to identify expressions and emotional states on people's facial expressions.
