Recent human functional imaging studies have linked the processing of pleasant visual stimuli to activity in mesolimbic reward structures. However, whether the activation is driven specifically by the pleasantness of the stimulus, or by its salience, is unresolved. Here we find in two studies that free viewing of pleasant images of erotic and romantic couples prompts clear, reliable increases in nucleus accumbens (NAc) and medial prefrontal cortex (mPFC) activity, whereas equally arousing…

Emotional imagery: Assessing pleasure and arousal in the brain's reward circuitry

Findings provide strong evidence that pleasurable text‐driven imagery engages a core appetitive circuit, including NAc, mPFC, and the amygdala, which is modulated by the emotional intensity of appetitive and aversive cues.

Noninvasive Stimulation of the Ventromedial Prefrontal Cortex Enhances Pleasant Scene Processing

The convergence of stimulation effects across independent groups of healthy participants and complementary neuroimaging methods (fMRI, MEG) provides a basis for further investigation of a potentially therapeutic use of this novel stimulation approach in patients with depression or other affective disorders.

A direct comparison of appetitive and aversive anticipation: Overlapping and distinct neural activation

Hemodynamic and electrocortical reactivity to specific scene contents in emotional perception.

Emotional scene perception is characterized by enhanced neural activity across broad regions of visual cortex, the frontoparietal network, and anterior corticolimbic structures, and activation enhancement is strongly related to self-reported emotional arousal evoked by scene stimuli.

Behavioral activation system modulation on brain activation during appetitive and aversive stimulus processing.

The reinforcement sensitivity theory (RST) proposed the behavioral activation system (BAS) as a neurobehavioral system that is dependent on dopamine-irrigated structures and that mediates the

Noninvasive Stimulation of the Ventromedial Prefrontal Cortex Indicates Valence Ambiguity in Sad Compared to Happy and Fearful Face Processing

MEG and behavioral results showed that happy faces promoted a relative positivity bias after excitatory compared to inhibitory tDCS, visible in left orbitofrontal cortex and in the emotion-primed dot-probe task.

Brain Activations to Emotional Pictures are Differentially Associated with Valence and Arousal Ratings

Findings support the notion that the amygdala is primarily involved in processing of unpleasant stimuli, particularly to more arousing unpleasant stimuli.

Activation of the visual cortex in motivated attention.

It is suggested that more extensive visual system activation reflects "motivated attention," in which appetitive or defensive motivational engagement directs attention and facilitates perceptual processing of survival-relevant stimuli.

Emotional Facilitation of Sensory Processing in the Visual Cortex

The hypothesis that sensory encoding of affective stimuli is facilitated implicitly by natural selective attention is supported, suggesting that the affect system not only modulates motor output, but already operates at an early level of sensory encoding.

Affective picture perception: gender differences in visual cortex?

Men and women showed reliably greater visual cortical reactivity during both pleasant and unpleasant pictures, relative to neutral, consistent with the view that the motivational relevance of visual stimuli directs attention and enhances elaborative perceptual processing.

Amygdala response to both positively and negatively valenced stimuli

A role for the amygdala in processing emotional stimuli that extends beyond negative and fearful stimuli is demonstrated, and arousal level is clearly demonstrated to modulate the amygdala response.

Human Striatal Response to Salient Nonrewarding Stimuli

A role of the striatum in coding nonrewarding salient events is demonstrated and a functional subdivision of thestriatum according to the behavioral relevance of the stimuli is suggested.
