Contribution of estradiol levels and hormonal contraceptives to sex differences within the fear network during fear conditioning and extinction
Hwang, Moon Jung; Zsido, Rachel G.; Song, Huijin; Pace-Schott, Edward F.; Miller, Karen Klahr; Lebron-Milad, Kelimer; Milad, Mohammed R.; Marin, Marie-France (BioMed Central, 2015)Background: Findings about sex differences in the field of fear conditioning and fear extinction have been mixed. At the psychophysiological level, sex differences emerge only when taking estradiol levels of women into ... -
Correlations between psychological tests and physiological responses during fear conditioning and renewal
Martínez, Karen G; Castro-Couch, Melissa; Franco-Chaves, José A; Ojeda-Arce, Brenda; Segura, Gustavo; Milad, Mohammed R; Quirk, Gregory J (BioMed Central, 2012)Background: Anxiety disorders are characterized by specific emotions, thoughts and physiological responses. Little is known, however, about the relationship between psychological/personality indices of anxiety responses ... -
Ethnic Differences in Physiological Responses to Fear Conditioned Stimuli
Martínez, Karen G.; Franco-Chaves, José A.; Milad, Mohammed R.; Quirk, Gregory J. (Public Library of Science, 2014)The idea that emotional expression varies with ethnicity is based largely on questionnaires and behavioral observations rather than physiological measures. We therefore compared the skin conductance responses (SCR) of ... -
An fMRI study of unconditioned responses in post-traumatic stress disorder
Linnman, Clas; Zeffiro, Thomas A; Pitman, roger k; Milad, Mohammed Ragib (BioMed Central, 2011)Background: Both fear and pain processing are altered in post-traumatic stress disorder (PTSD), as evidenced by functional neuroimaging studies showing increased amygdala responses to threats, and increased insula, putamen ... -
Mindfulness-Based Stress Reduction, Fear Conditioning, and The Uncinate Fasciculus: A Pilot Study
Hölzel, Britta K.; Brunsch, Vincent; Gard, Tim; Greve, Douglas N.; Koch, Kathrin; Sorg, Christian; Lazar, Sara W.; Milad, Mohammed R. (Frontiers Media S.A., 2016)Mindfulness has been suggested to impact emotional learning, but research on these processes is scarce. The classical fear conditioning/extinction/extinction retention paradigm is a well-known method for assessing emotional ... -
A parametric study of fear generalization to faces and non-face objects: relationship to discrimination thresholds
Holt, Daphne J.; Boeke, Emily A.; Wolthusen, Rick P. F.; Nasr, Shahin; Milad, Mohammed R.; Tootell, Roger B. H. (Frontiers Media S.A., 2014)Fear generalization is the production of fear responses to a stimulus that is similar—but not identical—to a threatening stimulus. Although prior studies have found that fear generalization magnitudes are qualitatively ... -
Sex Differences in the Neurobiology of Fear Conditioning and Extinction: A Preliminary fMRI Study of Shared Sex Differences with Stress-Arousal Circuitry
Lebron-Milad, Kelimer; Milad, Mohammed Ragib; Abbs, Brandon R.; Linnman, Clas; Rougemount-Bücking, Ansgar; Zeidan, Mohammed A.; Holt, Daphne J.; Goldstein, Jill M. (BioMed Central, 2012)Background: The amygdala, hippocampus, medial prefrontal cortex (mPFC) and brain-stem subregions are implicated in fear conditioning and extinction, and are brain regions known to be sexually dimorphic. We used functional ... -
Sex Differences, Gonadal Hormones and the Fear Extinction Network: Implications for Anxiety Disorders
Lebron-Milad, Kelimer; Milad, Mohammed Ragib (BioMed Central, 2012)Convergent data from rodents and human studies have led to the development of models describing the neural mechanisms of fear extinction. Key components of the now well-characterized fear extinction network include the ... -
Sleep and REM sleep disturbance in the pathophysiology of PTSD: the role of extinction memory
Pace-Schott, Edward F.; Germain, Anne; Milad, Mohammed R. (BioMed Central, 2015)Post-traumatic stress disorder (PTSD) is accompanied by disturbed sleep and an impaired ability to learn and remember extinction of conditioned fear. Following a traumatic event, the full spectrum of PTSD symptoms typically ...
