“…The scenes also differed in rated arousal, F (2, 9) = 21.5, p < 0.001, with pleasant and unpleasant scenes evoking enhanced arousal relative to neutral scenes and marginally greater arousal evoked by unpleasant, relative to pleasant scenes, t (10) = 1.94, p = 0.08, d = 0.59. We conducted pairwise analyses ( t tests) of each of our five categories and found that the ratings from these 11 individuals did not reliably differ from ratings of the same scene stimuli taken from a separate sample of 26 University of Georgia undergraduates included in a previous study (Sabatinelli et al, ). Thus, we consider the ratings from this subset of participants to be representative of the total sample of 19 in the current study.…”

“…The fMRI recording was performed first, and for each session participants reviewed and signed an informed consent approved by the University of Georgia Human Subjects Review Board, detailing the study and experimental procedures. The 19 participants included here were a subset from a sample of 42 fMRI subjects published previously (Sabatinelli et al, ) that returned for the EEG session.…”

“…The two functional blocks were each comprised of four oblique axial slices (Figure ; 64 × 64 EPI, 18 cm field of view, 5 mm thickness, 1.5 mm gap, 25º flip angle, 30 ms TE, 250 ms TR) situated over ventral and dorsal regions of the brain in order to obtain maximal coverage of amygdala, fusiform gyrus (FG), and occipital cortex (ventral), as well as the IPS and frontal eye fields (FEF; dorsal). These focused slice prescriptions were specified to enable rapid sampling at 250 ms TR, which was relevant to research questions addressed in a separate publication regarding BOLD signal timing and directional connectivity analysis (Sabatinelli et al, ). Each set of four axial slices was manually positioned using the T1 image for identification of landmarks based on each participant’s anatomy, such that the ventral prescription was centered on amygdala and tilted to cover ventral inferior temporal and occipital lobe, and the dorsal prescription was centered on the IPS and tilted to cover the superior frontal lobe (Figure ).…”

Emotional scene perception is characterized by enhanced neural activity across broad regions of visual cortex, the frontoparietal network, and anterior corticolimbic structures. In human fMRI and electrocortical experiments, activation enhancement is strongly related to self‐reported emotional arousal evoked by scene stimuli. However, an additional bias in reaction to pleasant scenes has been reported in a subset of emotion‐enhanced brain regions. Human fMRI and primate electrophysiological studies show biased frontoparietal network activity in response to rewarding cues. In addition, activation in lateral occipital regions may show a bias in pleasant scene perception, as shown in fMRI and in the early posterior negativity (EPN) ERP component. To define this potential pleasure bias, we presented a balanced set of naturalistic scenes to participants during separate fMRI and ERP recording sessions. Consistent with past work, the amplitude of the slow‐wave late positive potential (LPP), as well as hemodynamic activity in fusiform gyrus and amygdala, showed equivalent enhancement across highly arousing pleasant and unpleasant, relative to neutral scenes. In addition to this emotional enhancement, the EPN component, as well as hemodynamic activity in lateral occipital cortex and frontoparietal network, showed greater reactivity during highly arousing pleasant relative to unpleasant scenes, consistent with a pleasure bias. The interpretation of this pattern of reactivity is discussed with respect to selective and evolved attention mechanisms.

“…These are key regions involved in visual identification, emotion, and selective attention processes (Sabatinelli et al, 2014, 2009) and their greater relative activation during GWLs likely reflects greater salience to smokers viewing these emotional scenes. This pattern of activation is consistent with the results found by a prior study which compared response to GWLs with response to TOL warning associated with a non-graphic image, which found the difference between the two warnings to be localized in the occipital lobe, fusiform gyrus, amygdala, hippocampus, insula, and inferior frontal cortex (Wang et al, 2015).…”

Neural correlates of graphic cigarette warning labels predict smoking cessation relapse

Exposure to graphic warning labels (GWLs) on cigarette packaging has been found to produce heightened activity in brain regions central to emotional processing and higher-order cognitive processes. The current study extends this literature by using functional magnetic resonance imaging (fMRI) to investigate neural activation in response to GWLs and use it to predict relapse in an evidence-based smoking cessation treatment program. Participants were 48 treatment-seeking nicotine-dependent smokers who completed an fMRI paradigm in which they were exposed to GWLs, text-only warning labels (TOLs), and matched control stimuli. Subsequently, they enrolled in smoking cessation treatment and their smoking behavior was monitored. Activation in bilateral amygdala, right dorsolateral prefrontal cortex, right inferior frontal gyrus, left medial temporal gyrus, bilateral occipital lobe, and bilateral fusiform gyrus was greater during GWLs than TOLs. Neural response in the ventromedial prefrontal cortex (vmPFC) during exposure to GWLs (relative to a visual control image) predicted relapse during treatment beyond baseline demographic and dependence severity, but response in the amygdala to GWLs did not. These findings suggest that neurocognitive processes in the vmPFC may be critical to understanding how GWL’s induce behavior change and may be useful as a predictor of smoking cessation treatment prognosis.

“…This possibility has not yet been studied, although the ability of prefrontal areas to modulate occipital activity is now generally accepted (Cavada et al, 2000; Rainer and Miller, 2000; Petrides et al, 2002; van Turennout et al, 2003; Hasson et al, 2004; Bar et al, 2006; Deshpande et al, 2010; Chaumon et al, 2013; Volberg et al, 2013; Volberg and Greenlee, 2014). Moreover, the amygdala provides input to the frontal cortex that can affect perception (Sabatinelli et al, 2014), and emotion affects the likelihood that arousing information will be processed (Phelps et al, 2006), as well as how quickly it is processed (Ohman et al, 2001). The amygdala is also connected to both the ventral and dorsal visual streams; through these pathways, top-down signals may be carried to the visual cortex to enhance visual processing for emotionally salient stimuli (Furl et al, 2013), which may shift balances in global and local processing.…”

Comparison of visual perceptual organization in schizophrenia and body dysmorphic disorder

People with schizophrenia are impaired at organizing potentially ambiguous visual information into well-formed shape and object representations. This perceptual organization (PO) impairment has not been found in other psychiatric disorders. However, recent data on body dysmorphic disorder (BDD), suggest that BDD may also be characterized by reduced PO. Similarities between these groups could have implications for understanding the RDoC dimension of visual perception in psychopathology, and for modeling symptom formation across these two conditions. We compared patients with SCZ (n=24) to those with BDD (n=20), as well as control groups of obsessive-compulsive disorder (OCD) patients (n=20) and healthy controls (n=20), on two measures of PO that have been reliably associated with schizophrenia-related performance impairment. On both the contour integration and Ebbinghaus illusion tests, only the SCZ group demonstrated abnormal performance relative to controls; the BDD group performed similarly to the OCD and CON groups. In addition, on both tasks, the SCZ group performed more abnormally than the BDD group. Overall, these data suggest that PO reductions observed in SCZ are not present in BDD. Visual processing impairments in BDD may arise instead from other perceptual disturbances or attentional biases related to emotional factors.
