A neuromodulatory role for the human amygdala in processing emotional facial expressions.
Functional neuroimaging confirmed that the amygdala and some of its functionally connected structures mediate specific neural responses to fearful expressions and demonstrated that amygdalar responses predict expression-specific neural activity in extrastriate cortex.
Modulation of connectivity in visual pathways by attention: cortical interactions evaluated with structural equation modelling and fMRI.
A structural equation model of the interactions among these dorsal visual pathway areas revealed increased connectivity between V5 and PP related to attention, and attributed the source of modulatory influences, on the posterior visual pathway, to the prefrontal cortex (PFC).
Episodic Future Thinking Reduces Reward Delay Discounting through an Enhancement of Prefrontal-Mediotemporal Interactions
Multisubject fMRI Studies and Conjunction Analyses
It is suggested that activations common to all subjects reflect aspects of functional anatomy that may be "typical" of the population from which that group was sampled, and these commonalities can be identified by a conjunction analysis of the activation effects.

A reduction of ventral striatal and ventromedial prefrontal activation in the pathological gamblers was observed that was negatively correlated with gambling severity, linking hypoactivation of these areas to disease severity.
Oxytocin Attenuates Amygdala Responses to Emotional Faces Regardless of Valence

Different behavioral effects of oxytocin seem to be closely related its specific modulatory influence on subregions within the human amygdala.
Odor Cues During Slow-Wave Sleep Prompt Declarative Memory Consolidation
It is shown that reactivation indeed causes memory consolidation during sleep, and functional magnetic resonance imaging revealed significant hippocampal activation in response to odor re-exposure during SWS.
