Professor awarded for fear research

Joseph LeDoux, professor of neuroscience and psychology, received the William James Fellow Award from the Association for Psychological Science in recognition of his research of memory and emotion in early April.

LeDoux said he was humbled to have been given the William James Fellow Award.

“It’s a great honor and completely out of the blue,” LeDoux said.

LeDoux said he did not initially intend to enter the field of psychology — he studied marketing at Lousiana State University. While studying the marketing side of business, however, his interest in psychology grew. After graduate school, LeDoux began researching split-brained patients for his PhD.

His research, which focuses on fear, shows how people can respond to danger before they know what they are responding to.

In a three-year study, LeDoux and other researchers lightly shocked rats the same time they played a sound. Through this process, the researchers learned how the rats’ brains detected and responded to danger. The rats’ blood pressures and heart rates would increase, showing the researchers that the rats learned to fear the sound.

LeDoux said memory is an interesting area of research and looks at the way implicit memory is separate from the conscious experience.

“We found that whenever you form a new memory, protein synthesis is required for all that the cell is going to do,” LeDoux said. “That has been the core of my work, trying to find out how implicit memory takes place. Not only do you need protein synthesis in [the] learning phase, but also when you retrieve memory.”

LeDoux said memories are not just carbon copies of experience. They are on-the-spot reconstruction, which means they can be fallible.

“When we retrieve memories there’s the opportunity to update it and remember it differently,” LeDoux said. “That updating process is dependent on the synthesis of proteins.”

LeDoux describes research as a slow and long incremental process, which speaks to his dedication as a scientist.

“All of a sudden you might do something that doesn’t make any sense, but then it just makes you jump to the next thing,” LeDoux said.

LeDoux currently teaches freshman honors seminars and an upper-level undergraduate seminar on his book “The Emotional Brain” at NYU.

Aside from being a professor, LeDoux has a deep love for music and is a musician in a band. His band, the Amygdaloids, is made up of three other scientists from NYU, and is a reference to the amygdala in the brain.

Daniela Schiller, a postdoctoral fellow researching neuroscience and psychiatry and fellow band member, said LeDoux is a crucial part of the band.

“LeDoux is the quiet engine that drives the band,” Schiller said.

Continuing his research, LeDoux’s interests are evolving toward how the awakening of an emotional aspect of a memory can occur without the elimination of conscious memory. LeDoux is also interested in not only how brains react to danger, but also how they act.

“Freezing in your tracks may be the reaction, but then there is the action,” LeDoux said.

    Applying for an editor position: Applications for editor positions during the fall or spring semesters are available twice each academic year and can be found here when posted. Applications for the Fall 2012 semester are closed, but check back for Spring 2013. Those who wish to apply are urged to publish pieces in the newspaper and contact current editors for shadowing.

    History of the Washington Square News:

    The Washington Square News is the official daily student newspaper of New York University and serves the NYU, Greenwich Village, and East Village communities. Founded as an independent newspaper in 1973, the WSN allows its undergraduate writers and photographers to cover campus and city news and continues to grow its strong body of award-winning journalists and photographers.

  • The WSN has a circulation of about 60,000 and can be found in over a hundred purple bins distributed throughout campus. It is published Monday through Thursday during the fall and spring semesters and online on Friday, with additional special issues published in the summer. The newspaper recently revamped its website during the Fall 2012 semester.

    Like few campus newspapers in the country, the paper is editorially and financially independent from the university and is solely responsible for selling advertisements to fund its production. The WSN, including its senior staff, is run solely by current undergraduate students and the business-division is largely student-operated as well.

    A Board of Directors comprised of alumni, NYU professors and working news media professionals serves as advisors to the paper. Board members have no control in the WSN's editorial policy or newsroom operations. Alumni of the newspaper are established and leading journalists in such news organizations as The New York Times, The Wall Street Journal, NBC news, ABC news, Fox News, and USA Today.
