Interpreting what different types of laughter mean requires different brain regions. chris.huggins

I amuse you? Judging laughter is no joke for the brain

There’s nothing quite like overhearing a hearty belly-laugh, unless perhaps it’s having a good chortle yourself. The happy likelihood is that, in any case, one guffaw will lead to the other. Laughter is…

Neuromarketing for the compact Fairfax papers was a no-brainer

If there’s one thing that could be observed from Fairfax’s move to publish its first tabloid-sized broadsheets it was a surprising level of neuro-illiteracy. Fairfax’s head of advertising, Sarah Keith…
