The Graduate College announces launch of the Graduate Faculty Mentor Academy

April 8, 2020

For 30 years, the Arizona State University Graduate College has honored faculty members for their exemplary service and commitment to graduate education through recognition at its Outstanding Faculty Mentor Awards

In keeping with this dedication to the significance of mentorship in graduate education, the Graduate College is excited to announce the creation of the Graduate Faculty Mentor Academy. group of faculty interacting with students Download Full Image

The purpose of the Graduate Faculty Mentor Academy is to recognize, establish and promote standards for the role of mentoring among faculty, graduate students and postdoctoral scholars at ASU. Members of the academy will advance best practices for mentoring graduate students and postdoctoral scholars, for mentoring teaching assistants and for recognizing excellence and innovations in mentoring.

According to Amanda Athey, director of Graduate Student Support Resources in the Graduate College, “We have so many talented faculty mentors at ASU, it was important for us to involve them more directly into our programming. What better way to improve our graduate student mentoring program than by asking faculty to play a leading role.”

Academy membership will include prior Outstanding Faculty Mentor Award recipients and faculty recognized by deans for leadership in mentoring graduate students. Future Outstanding Faculty Mentor Award recipients will be invited to become members of the academy as well. 

“Committed mentors are very important for graduate students because they serve as models for research and career advancement as well as important interpersonal support,” noted Graduate School Dean Alfredo J. Artiles. “Launching the Faculty Mentor Academy is the next step in the Graduate College’s efforts to build a strong culture for mentoring graduate students at ASU.”

Anterior insula activation restores prosocial behavior in animal model of opioid addiction

April 8, 2020

Are the social and interpersonal problems associated with opioid addiction reversible?

A new study in animals from the Arizona State University Department of Psychology suggests they are. Previously, the researchers used a model of opioid addiction and empathy to show that animals stopped prosocial behaviors — helping another animal — when heroin was available. The same research group has now shown that activating the anterior insula restored prosocial behaviors. The study will be published in Social Neuroscience and is now available online.

“As a master’s student, I led support groups for opioid addicts, and the biggest problems people wanted help dealing with were social. Our finding in an animal model of opioid addiction that chemogenetic activation of the anterior insula restores prosocial behavior suggests a glimmer of hope that some of the social behavioral deficits in opioid addiction are not permanent,” said Seven Tomek, who just defended her doctoral dissertation at ASU. Tomek is first author on the paper and received training in substance abuse treatment while earning her master’s degree in clinical psychology from the University of North Carolina, Wilmington.  

To measure prosocial behavior, the researchers trained animals to free another animal that was trapped in a clear plastic tube. The animals had access to heroin for two weeks and then were given the choice of consuming heroin or helping another animal. Like before, the animals again chose heroin over helping another. 

To try and restore the prosocial behaviors in the animals, the research team targeted a brain region involved in both prosocial behaviors like helping and addictive behaviors like craving: the anterior insula. 

“We designed our animal study based on work in people showing that damage in the anterior insula area — from a stroke for example — was correlated with easily quitting cigarette smoking,” Tomek said. “This brain area is also important for motivation and emotions in people.”

The insula is nicknamed the “hidden lobe” because it is tucked underneath the brain’s frontal, parietal and temporal lobes. The research team used chemogenetic methods to activate the anterior insula. These methods work like a smart lock, letting scientists selectively activate specific types of neurons in a brain region.

“Once we activated the anterior insula, the animals started rescuing the trapped animals again,” Tomek said.

The research team tested the role of anterior insula activation twice. In the first experiment, the animals who underwent “activation” of the anterior insula helped other animals 67% of the time when heroin was available. The control group only helped other animals 17% of the time. In the second experiment, activation of the anterior insula was again associated with helping other animals 67% of the time. The second control group helped other animals 44% of the time.

“This work demonstrates an important role for the anterior insula in opioid addiction and shows the possibilities of changing a social behavior that has been compromised by drug use,” said Foster Olive, professor of psychology at ASU and senior author on the paper.

Gabriela Stegmann, Jonna Leyrer-Jackson and Jose Piña also contributed to the work. This study was supported by the National Institute on Drug Abuse, the Society of Addiction Psychology, and Arizona State University.
