Abstract Emotion regulation is hypothesized to be a multifaceted process by which individuals willfully modulate the intensity and direction of emotional response via prefrontally-mediated
ip t
inhibition of subcortical response-related regions of the brain. Here we employ Activation
Likelihood Estimation (ALE) meta-analysis of functional magnetic resonance imaging studies to
cr
1) reveal a consistent network of structures active during emotion regulation, 2) identify the
us
target regions inactivated by the willful regulation process, and 3) investigate the consistency of activated structures associated with downregulation and upregulation. Results reveal signal
an
change in bilateral amygdala / parahippocampal gyrus that decreased in downregulated states and increased in upregulated states, while cortical regions including superior frontal gyrus,
M
cingulate, and premotor areas exhibited enhanced activity across all regulation conditions. These results provide consistent evidence for the role of amygdala activity in experienced
d
emotional intensity, where intentional dampening and exaggeration are clearly expressed.

However, the execution of emotional upregulation and downregulation may involve distinct

subsets of frontocortical stuctures.

1. Introduction The willful modulation of responses to emotionally evocative stimuli is thought to involve interactions among the lateral prefrontal cortex (LPFC), orbitofrontal cortex (OFC), anterior
ip t
cingulate cortex (ACC), and amygdala (Banks et al., 2007; Kim and Hamann, 2007; Ochsner et al., 2002; Ochsner et al., 2004). Among other functions, the LPFC and ACC are critical in the
cr
performance of cognitive control tasks such as conflict monitoring (van Veen and Carter, 2002),
us
working memory (Rypma et al., 1999), and the guidance of attention (Banich et al., 2000), whereas the amygdala is heavily involved in emotional processing (Garavan et al., 2001; Lane
an
et al., 1999). Thus, the association of these brain structures identified with emotion regulation tasks is consistent with their ascribed roles in human behavior. The initial goal of the current
M
work is to identify a consistent set of activated brain regions reported in functional magnetic resonance imaging (fMRI) investigations of emotional regulation processes using quantitative
d
meta-analysis, taking advantage of enhanced statistical power and dampening the contributions
te
of idiosyncratic experimental designs to reveal a consistent and reliable activated network (Eickoff et al., 2012). Our second goal exploits the distinctive nature of the proposed emotion
Ac ce p
regulation network, in which an intentional process is associated with both the activation of regulating structures and inhibition (or in some cases enhancement) of regulated structures, which is particularly amenable to the fMRI measure that provides estimates of signal decreases as well as increases.
Investigations of the brain mechanisms of emotional regulation often include conditions in which participants are instructed to modulate their affective state in a single direction (e.g., to decrease felt emotion). Distinct brain regions have been identified in the comparatively few paradigms that have included both increase and decrease tasks, suggesting directiondependent regulation networks (Kim and Hamann, 2007; Urry et al., 2006). This creates somewhat of an interpretational challenge in assessing the specificity of an emotional regulation
Page 4 of 33
network, in that different control structures or relative activity levels of nodes in a consistent control network may exist across downregulation and upregulation demands. Meta-analysis may therefore be useful to compare results from emotional enhancement and suppression
ip t
conditions across a number of studies to detect the presence of direction-specific mechanisms involved in emotion regulation.
cr
Three meta-analytic investigations of emotion regulation have been published recently
us
(Buhle et al., 2013; Diekhof et al., 2011; Kohn et al., 2014), however the present effort will differ from these works in multiple ways. One significant distinction is that ours will include a contrast

in which enhanced emotional reactivity is assessed, thus providing an opportunity to test how the direction of regulation alters the composition of brain structures involved. A second novel

feature of our meta analysis is the addition of a contrast depicting activation decreases during regulation states. This inclusion combines the advantages of the distinctive psychological task in

regional brain activity. Finally, we hope to include a larger number of studies than has been
Ac ce p
To address these research questions, the current work employed the latest iteration of the Activity Likelihood Estimation (ALE) fMRI meta-analysis method (Eickoff et al., 2009) to combine the results of emotional regulation studies published over a 10 year period, including studies in which increased and decreased blood oxygen level dependent (BOLD) signal were reported during experimental conditions in which individuals downregulated or upregulated their affective state.

2. Methods 2.1. Article selection Articles from 1994 through 2014 were identified using a specific search string in the
ip t
PubMed database:
("1994/01/01"[Publication Date]: "2014/12/31"[Publication Date]) AND ((emotion* OR
cr
affective OR fear OR valence ) AND (regulat* OR suppress* OR reappraisal) AND (fMRI OR
us
neuroimag* OR "functional MRI" OR "functional magnetic resonance imaging")).
Studies were included if the authors reported whole-brain coordinates in Talairach or MNI space
an
and sampled at least five subjects over 18 years of age. Contrasts that compared regulation conditions (e.g., instructed reappraisal or suppression) to non-regulation or baseline conditions
M
(e.g. passive viewing) were included. In studies for which coordinate tables resulting from more than one contrast were reported (e.g., downregulation and upregulation contrasts), both were
d
included. Only the results from within-subject contrasts were included, which accounted for the
te
great majority of studies. Studies of clinical populations were excluded, however results from healthy control groups reported in clinical studies were included if listed separately.
