There is widespread evidence that people tend to take risks. However, there is very little research into how genetic disposition translates into risky behavior. The only study to date looking at structural brain imaging data came from a small, non-representative sample of just a few hundred people.
An international team led by neuroscientists at UZH studied the genetic information and brain scans of more than 25,000 people to understand how genetic characteristics correlate with risk-taking behaviors such as drinking, smoking, driving and promiscuity.
The large sample allows the researcher to control for several variables such as age, gender and other factors to reveal that there is a relationship between brain function and anatomy as well as risky behavior.
The study, published in the Nature Human BehaviorExternal link last week, confirmed several areas of the brain thought to be associated with risky behavior. These include the hypothalamus, where hormones such as dopamine are released, and the prefrontal cortex, which plays an important role in self-control and cognitive judgment.

An Auckland woman talks about her hair laser removal experience that went wrong. Photo / Provided
An Auckland woman left her first laser hair removal session delighted that she had found a hair removal solution that worked.
But at the end of the second session, the excitement was gone.
He said he had burns so badly during the two-minute session that he needed medical attention.
The woman, who did not want to be named, is currently undergoing a popular beauty treatment on her chin and jaw.
She expected some level of discomfort during the session, but when it became too painful, she asked the beautician to stop.
The two-minute session caused burns to his face and neck. She stayed at the clinic for an hour after a session holding an ice pack on her aching face, before going to the Shorecare emergency care clinic at Smales Farm.
She was bandaged and sent home with painkillers and instructions not to go out in the sun for a week.
He is not quite sure how the burns occurred but suspects the machine was used with a higher intensity than it should have been for his skin type.
She decided to tell her story to bring attention to the fact that laser hair removal could lead to mistakes.
“I don’t want anyone to experience this,” he said.
“I suffered. The burns were really bad. But according to the doctor, they haven’t reached the underlying skin layer. But it was a very bad experience for me.”
Four days after that incident, he was still in pain.
She struggled to sleep in the days following the appointment, placing a fan near her head at night to relieve the pain from the burns.
She said she couldn’t see herself getting laser treatment again anytime soon.
The New Zealand Laser Clinic yesterday offered an apology to the woman.
Michelle Taylor, the company’s New Zealand country manager, said it offered a “sincere apology” for the incident.
“Each of our clinics follows strict protocols and procedures for all therapists, nurses and doctors,” said Taylor.
“Although incidents like this are very unusual, a thorough review is being carried out with our clinic and management.
“We have contacted the client so that our medical director can determine what treatment will aid their recovery, in consultation with the Medical Advisory Committee of our dermatologist specialists. We are very sympathetic to this incident and wish them a full recovery.”
Meanwhile, a customer has filed a complaint with the Auckland Council.
Under the Health and Hygiene Act 2013, businesses providing laser and pulsed light treatments must have board approval.
Auckland Council’s alcohol and environmental health manager, Mervyn Chetty, said there are currently 56 businesses providing pulse beam and laser treatments that are registered on the board.
“This business is inspected annually by the Environmental Health team to ensure compliance with laws and regulations and the code of ethics,” he said.
The board has received two complaints regarding laser treatment and regulatory violations this year, which are being investigated.
The New Zealand Laser Clinic said its clinic adhered to Auckland Council guidelines and the company “went beyond code requirements and the clinic has implemented extra safety measures, adhering to the most stringent standards in Australia and New Zealand”.

A New Zealand man was found dead after an alleged shark attack during a snorkeling trip in South Australia.
Duncan Craw’s Kiwi family said it was impossible to describe the hole a “cheerful, loving, helpful” and naughty man would leave in the lives of those he knows.
Relatives of the 32-year-old man said he moved to Australia from New Zealand at a young age before recently traveling to South Australia from his home in Warrnambool, Victoria, on a camping trip with his family.
However, while snorkeling in Port MacDonnell on a beautiful Thursday on a beautiful day, his wife Taylia lost her sight.
“The exact circumstances of Duncan’s disappearance are not yet known but given the discovery of a damaged wetsuit and sightings of the Great White in the area on Thursday, it appears that a shark was involved,” the family said in a statement.
His body has been found.
“Duncan loves to snorkel and accepts the dangers he may face at sea. He is very unlucky this time,” the statement said.
New Zealand’s Ministry of Foreign Affairs and Trade confirmed it had been contacted in connection with Craw’s death.
“The Ministry of Foreign Affairs and Trade has not yet been approached by Duncan Craw’s family for consular assistance,” said a spokesman for MFAT.
Craw is married and has a young son named Levi.
South Australian police inspector Campbell Hill told local media outlets that an emergency team was called to the scene around 5pm last Thursday.
“We were called to a reef break just outside Port MacDonnell where we were met there by the family,” Hill told reporters.
“The man could not be found and a large-scale search was initiated involving police officers, members of the water operations and air wing, local state emergency services and fisheries.
“There are also lots of locals helping with the search, standing on paddle boards and fishing boats, or standing on the beach with binoculars.”
A police helicopter spotted a Great White Shark in the area that night.
The next morning the search team finds a badly damaged wetsuit along with other equipment that Craw is known to have used.
“Unfortunately we have collected them all and it clearly describes a fatal shark attack,” said Hill.
Craw went missing just three days before his 33rd birthday.
He is described as a very hardworking and dedicated operations manager at an agricultural company in Warrnambool, where he grew up after moving from New Zealand at a young age.
“When he’s not farming, spending time with family, or working around the property he bought with his wife Taylia, he likes to meet friends and watch or play sports, including cricket for the Woolsthorpe Cricket Club,” his family said.
“He is also Levi’s best father and a beautiful husband and best friend to Tay, his high school sweetheart.”
“She is a cheerful, affectionate and helpful child. She is a good and brash brother to her sister. She is a fun, naughty and supportive partner who has a heart of gold.”
Craw’s death came when eight Australians were killed by sharks last year – the largest since 1929.
It also happened when 19-year-old Kaelah Marlow died at Bowentown Beach in New Zealand’s Bay of Plenty earlier this month.
“Viruses change over time, and we expect to see new strains as disease spreads,” said State Health Commissioner M. Norman Oliver, MD, MA. “We know this variant strain spreads faster among people than other strains currently circulating in our community, but we still have to learn more about whether it causes more severe disease. Because our state public health officials are closely monitoring the appearance of variant B.1.1.7 in our Commonwealth, it is important that all Virginia residents continue to follow mitigation measures. “
