University of Western Australia shark researcher Kara Yopak, who has dissected the brains of more than 150 species, said new studies of the great white shark's brain had revealed important similarities to human brains.
"Great white sharks have quite large parts of the brain associated with their visual input, with implications for them being much more receptive to repellents targeting visual markers," Ms Yopak said of the research, published in a special edition of the journal Brain, Behaviour and Evolution.
Most repellents now on the market target the electrosensitive pores on a shark's head which are used to detect the weak currents emitted by prey, by sending a strong electrical signal to drive them away.
Yopak said studies found this technology could be effective but failed to repel great whites in all cases. Understanding how their brains work could be vital to developing new deterrents, which could be something as simple as marking patterns on surfboards and wetsuits.
"A shark may recognise a poisonous sea-snake's markings and swim away, for example, and we can use this information to cue a response," she said.
"It's about understanding how their neurobiology affects their (behaviour)."
Yopak is part of a multidisciplinary team at the university's Oceans Institute working towards new commercial repellents.
Most sharks had been found to have brains of the same relative size as mammals or birds, she added, debunking any idea they are "tiny-brained eating machines".

Beat me to it, LMAO;)
Correct, most of the humans the shark brains are similar to become lawyers then run for office as a Dem.
I am thinking that “Bath Salts” makes the Human brain more like Shark brains...
i was going to say politicians..
i swore a few year ago i would never vote for a lawyer running for a political office again..
A lawyer was sailing his yacht out to sea, in hopes that it would weather the storm better at sea than in harbour. Unfortunately, the boat started taking on water, so the lawyer decided that he better try to swim for shore. As he dove into the surf, he saw two huge dorsal fins heading straight for him!
Fearing the worst, the lawyer decided to pray for the first time in his life, asking the Lord to save his life. To his surprise, instead of being eaten, two Great White sharks allowed him to grab hold of their fins, as they escorted him to shore.
An amazed police, officer watching for anyone who might venture onto the beach saw the sharks deposit the lawyer on the deserted beach. Before the policeman could ask about what he say, the lawyer said, "Professional courtesy."
An old joke, but a good one... especially if their specialty is divorce!
I about jumped out of my skin when I opened this thread and that picture popped out.
I have not been in the ocean above my knees since watching JAWS during its original run.
A little water-proof make-up, button fly swimming trunks and I'm good to go!
So where’s my frikken’ laser beam?
Another picture of lawyers ... this time selecting their next client!
The sharks had an article last week saying human brains were similar to theirs. It was posted all over their internet.

Thanks null and void.
