A time-dependent role of midline thalamic nuclei in the retrieval of fear memory
Increasing evidence indicates that the medial prefrontal cortex (mPFC) and the amygdala mediate expression and extinction of conditioned fear, but few studies have examined the inputs to these structures. The dorsal part ...
Reduced functional connectivity within the mesocorticolimbic system in substance use disorders: An fMRI study of Puerto Rican young adults
(Frontiers Media, 2016-05)
Studies of the mesocorticolimbic reward system (MCLS) and its relationship with impulsivity and substance use disorders (SUD) have largely focused on individuals from non-minority backgrounds. This represents a significant ...

Ethnic differences in perceived impairment and need for care
Latino children in the U.S. have high rates of unmet need for mental health services, perhaps due to biased perceptions of impairment and need for care by parents and providers. We tested this argument using an experimental ...
Revisiting the role of infralimbic cortex in fear extinction with optogenetics
(Society for Neuroscience., 2015)
Previous rodent studies have implicated the infralimbic (IL) subregion of the medial prefrontal cortex in extinction of auditory fear conditioning. However, these studies used pharmacological inactivation or electrical ...
Do Puerto Rican youth with asthma and obesity have higher odds for mental health disorders?
BACKGROUND: Island Puerto Rican (PR) youth experience disproportionately high asthma and obesity rates compared with other racial/ethnic groups on the U.S. mainland. Previous research has demonstrated associations of ...
