The Neural mechanisms of emotional control and flexibility
Dr. Schiller's line of research focuses on the neural mechanisms underlying emotional control. Because the environment we live in is constantly changing, our learned emotional responses need to be continuously updated to appropriately reflect current circumstances. Understanding the neural mechanisms that make such emotional flexibility may shed light on the impairments leading to anxiety disorders and may also promote new forms of treatment.
In her doctoral research she studied one such aspect of emotional learning, namely, the ability to acquire emotional responses to previously ignored stimuli, which is impaired in patients suffering from chronic schizophrenia. Under the mentorship of Ina Weiner, she developed an animal model of this symptom (persistent latent inhibition) and examined the underlying neural circuitry, as well as the efficacy of antipsychotic drugs in ameliorating it.
For post-doctoral training, Dr. Schiller chose to extend her knowledge to human emotional systems under the mentorship of Elizabeth Phelps and Joseph LeDoux. Together, they came up with a translational research program aimed at extending fundamental findings in rats to humans. This research project includes parallel findings in rats and humans on the recovery of extinguished fear, elucidation of the neural circuitry of flexible fear reversal, and how fear motivates instrumental responding. In addition, to extend these findings to more complex situations unique to humans, she's investigating how emotional systems are recruited to rapidly evaluate others during initial social encounters.
Finally, in extreme situations, when emotional memories become traumatic, it might be beneficial to erase fear memories altogether preventing them from resurfacing. New evidence in rats and other non-human species suggests this might be possible using pharmacological manipulations. However, these finding have yet to be demonstrated convincingly in humans. Dr. Schiller is currently testing this possibility, by examining whether emotional memories induced in the laboratory can be erased using beta-adrenergic receptor blockade as well as drug-free behavioral manipulations. These studies are essential in providing a critical link between animal models and the clinical population.

Multi-Disciplinary Training Area
Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr.Schiller did not report having any of the following types of financial relationships with industry during 2019 and/or 2020: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
