Schematic of task presentation, and examples of stimuli.

As described in the text, participants were shown pictures from the International Affective Picture System (Lang et al., 1988) and asked to report how the pictures made them feel (good, bad, or neutral). Note the pictures in this figure are not the exact pictures shown to participants from the International Affective Picture System as these are not to be made available online (https://csea.phhp.ufl.edu/media/iapsmessage.html). The erotic (https://www.flickr.com/photos/103039225@N05/14964085720) and happy (https://www.flickr.com/photos/moonjazz/2684228420) images are in the public domain and are reproduced here under a Public Domain Mark 1.0 licence (https://creativecommons.org/publicdomain/mark/1.0/).

Figure 1—figure supplement 1
Conceptual model of emotional integration and evaluation, adapted from Halgren and Marinković (1995), and informed more recently by results of a meta-analytic analysis by Riedel et al. (2018).

Widespread and focal dynamic corticolimbic neural networks embody a broad scope of circuitries linked to distinct functional systems for amalgamating cognitive with feeling aspects of emotions: Attention and orientation to a salient stimulus occurs in insular, anterior cingulate, prefrontal, and posterior parietal cortices; Emotional event appraisal, integration, and evaluation (as influenced by the ongoing emotional context and the perceiver’s personality), takes place in posterior cingulate, orbital and medial prefrontal cortex, and other neocortical sites (e.g., fusiform gyrus and superior temporal sulcus), and limbic structures (hippocampus and amygdala); Volition and decisions, which determine response choice, are generated in cingulate, precentral, premotor, and supplementary cortices.

Participants’ characteristics and drinking measures.

The boxplot represents participant characteristics. Appendix 1—table 1 shows the means, standard deviations, and significant differences. In the boxplot above, blue diamonds indicate mean values. Age, education, DHD, and LOS are expressed in years and DD is in ounces of ethanol per day (approximating daily drinks). LOS values were not applicable for two nonalcoholic control men and four nonalcoholic control women who reported never drinking. Abbreviations: DHD = Duration of Heavy Drinking (>21 drinks per week) in years; DD = Daily drinks; LOS = Length of sobriety in years. HRSD = Hamilton Rating Scale for Depression (Hamilton, 1960); VIQ = Wechsler Adult Intelligence Scale, 3rd ed. Verbal Intelligence Quotient; PIQ = Wechsler Adult Intelligence Scale, 3rd ed.

Percentage of behavioral ratings by condition, rating, group, and gender.

The boxplot represents the significant condition x rating x group interaction, and the significant condition x rating x gender interaction, for percentage rating of the pictures p<0.05 (Appendix 1—table 3). The group interaction is most clearly evident for the difference in the good and neutral ratings of the erotic pictures, with the alcoholic participants rating the pictures good less frequently; other picture types were rated more similarly by both the alcoholic and control groups. The gender interaction indicated that men rated erotic pictures as good more frequently than women. Blue diamonds indicate mean values. Figure 3—figure supplement 1 shows the reaction times. Abbreviations: ALC = Alcoholic participants; NC = Nonalcoholic Control participants.

Erotic vs. neutral stimuli elicited abnormal activation of the limbic system and cerebellum in alcoholic men.

A significant group x gender interaction in response to erotic vs. neutral stimuli was identified and is displayed as a green outline indicated by arrows. All inferior arrows designate the amygdala. Group mean contrast values are displayed in the four brain images located in the corners of the figure, and group comparisons are indicated by minus signs. Contrast values are overlaid on coronal cross sections. Images are displayed in radiological convention with the right hemisphere shown on the left.

Contrast values observed in the cluster for erotic vs. neutral conditions.

The split violin plot represents the Contrast Effect Size (CES; equivalent to ‘CON’ in SPM or ‘COPE’ in FSL) for the cluster in which a significant group x gender interaction was identified for the erotic vs. neutral contrast (p<0.05 after correction for multiple comparisons). Positive values indicate erotic >neutral, while negative values indicate erotic <neutral. Each point represents a single participant’s average CES for vertices within the cluster. This figure is meant to convey the variability in CES across participants that is not visible in Figure 4. Nonalcoholic control men had greater activation to erotic stimuli than neutral stimuli, and the contrast was more positive than was observed for alcoholic men. The pattern was reversed for women: Alcoholic women had lower contrast values than nonalcoholic women. Abbreviations: ALC = alcoholic participants; NC = nonalcoholic control participants.

Tables

Table 1
Peak voxel or vertex labels of significant clusters for group contrasts of each emotion vs. neutral condition.

Significant clusters (p<0.05 after correction for multiple comparisons) were observed for comparisons between alcoholic and control groups (for the entire sample and for men and women separately), along with group x gender interactions, for each of the four contrasts between each emotion condition compared to the neutral condition. Cortical regions were determined from the peak voxel or vertex. Overall, the table shows that the ALCM had widespread abnormalities in response to emotional stimuli, and that these effects were significantly different than the effects for the ALCW. Details are described in the text, Figure 4, Figure 5, and Figure 6, and in Appendix 1—tables 5, 6 and 7.

Abbreviations: LH = left hemisphere; RH = right hemisphere; Max = maximum −log10(p-value) in the cluster; VtxMax = vertex number at the maximum; size = surface area of cluster; XYZ = the MNI coordinates of the maximum; CWP = clusterwise p-value further corrected for the three spaces of left cortex, right cortex, and volume; CWPLow and CWPHi = 90% confidence interval for CWP; NVtxs = number of vertices in the cluster; ALC = alcoholic participants; NC = nonalcoholic Control participants.
