University of Western Australia shark researcher Kara Yopak, who has dissected the brains of more than 150 species, claims that a great white shark's brain has similarities to a human brain.
Her study is to be published in a special edition of the journal Brain, Behavior and Evolution.
Yopak told The Telegraph: "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."
"A shark may recognize a poisonous sea-snake's markings and swim away, for example, and can use this information to cue a response."
Yopak is part of a team at the University of Western Australia's Oceans Institute that is working on new shark repellents, as five people have died in the past ten months due to shark attacks.
Experts say the average number of shark attacks in Australian waters has increased with population growth and more water sports.
The Australian government, last month, announced a new catch-and-kill policy for sharks that come too close to beaches.
