The role of the Amygdala in the perception of reward [PDF]
, 1996 This study set out to examine the role of the amygdala in a number of appetitively motivated tasks. Experiment one was a position discrimination task with reversals, which in later reversals involved manipulation of some secondary reinforcers associated ...

The Contribution of the Amygdala to Reward-Related Learning and Extinction [PDF]
, 2017 There has been substantial research into the role of the amygdala in fear conditioning and extinction of conditioned fear. The role of the amygdala in appetitive conditioning is relatively less explored. Here, we will review research into the role of the

Amygdala Hypoactivity to Fearful Faces in Boys With Conduct Problems and Callous-Unemotional Traits [PDF]
, 2009 OBJECTIVE: Although early-onset conduct problems predict both psychiatric and health problems in adult life, little research has been done to index neural correlates of conduct problems. Emerging research suggests that a subgroup of children with conduct

Primate Amygdalo-Nigral Pathway for Boosting Oculomotor Action in Motivating Situations
iScience, 2020 Summary: A primary function of the primate amygdala is to modulate behavior based on emotional cues. To study the underlying neural mechanism, we first inactivated the amygdala locally and temporarily by injecting a GABA agonist.

Afraid of the dark: Light acutely suppresses activity in the human amygdala.
PLoS ONE, 2021 Light improves mood. The amygdala plays a critical role in regulating emotion, including fear-related responses. In rodents the amygdala receives direct light input from the retina, and light may play a role in fear-related learning.

Journal of the Mexican Federation of Radiology and Imaging, 2023 Introduction. Decreased hippocampal and amygdala volume has been associated with cognitive impairment. This study compared hippocampal and amygdala volumes in older adults with normal cognition and mild cognitive impairment (MCI) using magnetic resonance

Amygdala volume is not associated with MRI-based markers of early cardiovascular disease
Insights into ImagingBackground Recent PET studies suggest a link between amygdala activity and cardiovascular disease. Altered amygdala volumes are associated with increased stressor-evoked cardiovascular reactivity, which potentially increases the risk for cardiovascular ...

Fear, Anxiety, and the Amygdala [PDF]
Neuron, 2017 Lee et al. (2017) show that in the basolateral amygdala (BLA), fear and reward are encoded by phasic activation of distinct populations of neurons, while anxiety results in persistent activity changes. This study raises questions about how sensory inputs are encoded in the basal amygdala.

Involvement of human amygdala and orbitofrontal cortex in hunger-enhanced memory for food stimuli [PDF]
, 2001 We used positron emission tomography to measure regional cerebral blood flow (rCBF) in 10 healthy volunteers performing a recognition memory task with food and non-food items.
