Grimes, Tiffany – Reclaiming Children and Youth, 2012
Many fingers are pointed at today's youth who are maligned for problems of bullying, school dropout, teen violence, suicide, and sexual encounters at ever younger ages. But these are symptoms of the culture of discord adults have created for youth. Too many youth lack positive adult and peer relationships, a loving and caring community, and a…

Kodirov, Sodikdjon A.; Bonni, Kathrin; Wehrmeister, Michael; Lutz, Beat – Learning & Memory, 2021
The depolarization is also important for the short-term synaptic plasticity, known as depolarization-induced suppression of excitation (DSE). The two major types of neurons and their synapses in the lateral nucleus of amygdala (LA) are prone to plasticity. However, DSE in interneurons has not been reported in amygdala in general and in LA in…

Tottenham, Nim; Shapiro, Mor; Telzer, Eva H.; Humphreys, Kathryn L. – Developmental Science, 2012
In altricial species, like the human, the caregiver, very often the mother, is one of the most potent stimuli during development. The distinction between mothers and other adults is learned early in life and results in numerous behaviors in the child, most notably mother-approach and stranger wariness. The current study examined the influence of…

Wang, Shuo – Journal of Autism and Developmental Disorders, 2019
Prior studies have emphasized the contribution of aberrant amygdala structure and function in social aspects of autism. However, it remains largely unknown whether amygdala dysfunction directly impairs visual attention and exploration as has been observed in people with autism spectrum disorders (ASD). Here, gaze patterns were directly compared…

Bessières, Benjamin; Jia, Margaret; Travaglia, Alessio; Alberini, Cristina M. – Learning & Memory, 2019
The basolateral complex of amygdala (BLA) processes emotionally arousing aversive and rewarding experiences. The BLA is critical for acquisition and storage of threat-based memories and the modulation of the consolidation of arousing explicit memories, that is, the memories that are encoded and stored by the medial temporal lobe. In addition, in…

Chen, Xi; McCormick, Ethan M.; Ravindran, Niyantri; McElwain, Nancy L.; Telzer, Eva H. – Developmental Psychology, 2020
Guided by Eisenberg, Cumberland, and Spinrad's (1998) conceptual framework, we examined multiple components of maternal emotion socialization (i.e., reactions to children's negative emotion, emotion talk, emotional expressiveness) at 33 months of age as predictors of adolescents' amygdala-vmPFC connectivity and amygdala activation when labeling…

Rausch, Annika; Zhang, Wei; Beckmann, Christian F.; Buitelaar, Jan K.; Groen, Wouter B.; Haak, Koen V. – Journal of Autism and Developmental Disorders, 2018
Amygdala dysfunction plays a role in the social impairments in autism spectrum disorders (ASD), but it is unclear which of its subregions are abnormal in ASD. This study compared the volume and functional connectivity (FC) strength of three FC-defined amygdala subregions between ASD and controls, and assessed their relation to social skills in…

Gard, Arianna M.; Shaw, Daniel S.; Forbes, Erika E.; Hyde, Luke W. – Developmental Psychology, 2018
Models of differential susceptibility hypothesize that neural function may be a marker of differential susceptibility to context, but no studies have tested this hypothesis. Using a sample of 310 young men from low-income urban neighborhoods, this study investigated amygdala reactivity to facial expressions as a moderator of the relations between…

Schümann, Dirk; Sommer, Tobias – Learning & Memory, 2018
Emotional arousal enhances memory encoding and consolidation leading to better immediate and delayed memory. Although the central noradrenergic system and the amygdala play critical roles in both effects of emotional arousal, we have recently shown that these effects are at least partly independent of each other, suggesting distinct underlying…

Davis, Katie; Margolis, Amy E.; Thomas, Lauren; Huo, Zhiyong; Marsh, Rachel – Developmental Science, 2018
Pediatric reading disorder (RD) is associated with an increased risk of anxiety symptoms, yet understudied are the neurobiological factors that might underlie anxiety in children with RD. Given the role of the amygdala in anxiety, we assessed resting state functional connectivity of amygdalar subregions in children with RD to identify functional…

Dit-Bressel, Philip Jean-Richard; McNally, Gavan P. – Learning & Memory, 2015
Aversive stimuli not only support fear conditioning to their environmental antecedents, they also punish behaviors that cause their occurrence. The amygdala, especially the basolateral nucleus (BLA), has been critically implicated in Pavlovian fear learning but its role in punishment remains poorly understood. Here, we used a within-subjects…

Steinmetz, Adam B.; Ng, Ka H.; Freeman, John H. – Learning & Memory, 2017
Amygdala lesions impair, but do not prevent, acquisition of cerebellum-dependent eyeblink conditioning suggesting that the amygdala modulates cerebellar learning. Two-factor theories of eyeblink conditioning posit that a fast-developing memory within the amygdala facilitates slower-developing memory within the cerebellum. The current study tested…

Ferrara, Nicole C.; Cullen, Patrick K.; Pullins, Shane P.; Rotondo, Elena K.; Helmstetter, Fred J. – Learning & Memory, 2017
Generalization of fear can involve abnormal responding to cues that signal safety and is common in people diagnosed with post-traumatic stress disorder. Differential auditory fear conditioning can be used as a tool to measure changes in fear discrimination and generalization. Most prior work in this area has focused on elevated amygdala activity…

Herrington, John D.; Maddox, Brenna B.; Kerns, Connor M.; Rump, Keiran; Worley, Julie A.; Bush, Jennifer C.; McVey, Alana J.; Schultz, Robert T.; Miller, Judith S. – Journal of Autism and Developmental Disorders, 2017
Recent studies suggest that longstanding findings of abnormal amygdala morphology in ASD may be related to symptoms of anxiety. To test this hypothesis, fifty-three children with ASD (mean age = 11.9) underwent structural MRI and were divided into subgroups to compare those with at least one anxiety disorder diagnosis (n = 29) to those without (n…

Gebhardt, Christine; Albrecht, Doris – Learning & Memory, 2018
Capsaicin has been shown to modulate synaptic plasticity in various brain regions including the amygdala. Whereas in the lateral amygdala the modulatory effect of capsaicin on long-term potentiation (LA-LTP) is mediated by TRPV1 channels, we have recently shown that capsaicin-induced enhancement of long term depression (LA-LTD) is mediated by…
