The brain basis of emotion: A meta-analytic review (Lindquist, Wager, Kober, Bliss-Moreau & Barrett 2012)
A Behavioral and Brain Sciences target article (with ~30 commentaries and an authors’ response) reporting a large coordinate-based meta-analysis of the human neuroimaging literature on discrete emotion, run to adjudicate between a locationist account (fear=amygdala, disgust=insula, anger=OFC, sadness=ACC — see Fig. 1 of the target article) and Barrett’s psychological constructionist (“conceptual act model”) account, in which emotion categories are not natural kinds but situated conceptualizations built from domain-general operations. See lisa-feldman-barrett and basic-emotions.
The constructionist model being tested
Four hypothesized “ingredients,” none specific to emotion: core affect (raw valenced/aroused bodily sensation), conceptualization (using stored prior experience to make sensation meaningful, “situated conceptualization”), language (emotion words anchor otherwise loosely-bounded categories), and executive attention (selects which representations combine). Emotions are the joint product of these operations interacting like “ingredients in a recipe,” not discrete triggered modules.
Method
Density analyses (which voxels show more consistent activation for one emotion category than others), chi-square analyses (functional selectivity vs. specificity), and stepwise logistic regressions (which categories/methods predict activity in a given region), applied across neuroimaging contrasts of the experience or perception of anger, disgust, fear, happiness, and sadness published 1990–2007.
Anatomy findings directly relevant to this wiki
- Amygdala (locationist: fear): functionally selective for fear perception and disgust experience, but not specific — equally responsive to novel, uncertain, arousing, or salient stimuli of any valence. Reframed as a salience detector, not a fear centre.
- Anterior insula (locationist: disgust): functionally selective for disgust, but not specific to it. The paper’s positive reframing lands squarely on this wiki’s existing anatomical model — it explicitly invokes Craig (2002) and Craig (2009): “the anterior insula plays a key role in representing core affective feelings in awareness… is thought to be involved in the awareness of bodily sensations (Craig 2002) and affective feelings (Craig 2009).” Increased activation also occurs during body-movement awareness, gastric distension, and orgasm — states with nothing to do with disgust — consistent with a general interoceptive-awareness role. See insular-cortex.
- ACC (pACC, sACC, aMCC; locationist: sadness): not sadness-specific. pACC/sACC reframed as visceral-regulation sites (consistent with Craig’s “limbic motor cortex” framing); aMCC reframed as a response-selection/executive-attention site receiving exteroceptive (thalamic) and interoceptive (insular) input to direct attention and motor response.
- OFC (locationist: anger): not anger-specific. Reframed as integrating exteroceptive and interoceptive sensory information for context-sensitive behaviour (consistent with Seth & Friston’s later “VMA” characterization of the OFC — see visceromotor-areas).
- PAG: consistently active across the whole “neural reference space” for emotion (even though scanner participants lie still), but with no category specificity — consistent with a general autonomic/arousal role rather than discrete Panksepp-style rage/fear/lust circuits.
Is this a contradiction of Craig, or a vindication?
Mostly the latter, with one real tension. Lindquist et al.’s meta-analytic rejection of “insula = disgust” and “ACC = sadness” is not a rejection of Craig’s own claims — Craig never proposed disgust-specificity; his claim was always that the insula (AIC) supports general interoceptive/affective awareness, and Lindquist’s data support exactly that reading, citing Craig directly as source. The genuine tension is with Craig’s forebrain emotional asymmetry hypothesis (right AIC ↔ sympathetic/survival/withdrawal emotions like pain, anger, anxiety; left AIC ↔ parasympathetic/affiliative/approach emotions — see insular-cortex), which is a category-cluster-to-hemisphere locationist claim in Lindquist et al.’s sense, and would be predicted to fail the same functional-specificity tests this meta-analysis applies to single regions. Flagged here as an unresolved cross-paper tension, not merged or resolved.
New debate raised
This paper’s own target/commentary/response structure makes explicit a debate this wiki did not yet have a page for — not “do emotions have distinct autonomic signatures” (autonomic-specificity-of-emotion, about peripheral physiology) but whether discrete emotions map to distinct brain structures or networks at all. See the new locationist-vs-constructionist-brain-emotion debate, which also records Scherer’s commentary that the locationist/constructionist dichotomy mischaracterizes componential appraisal theory, and that “any evidence for brain mechanisms subserving categorization/conceptualization… does not privilege any theory on why or when” — a methodological caution about what a meta-analysis of this kind can and cannot decide between rival theories.
Bridge to interoceptive inference
Mog Stapleton’s commentary (see limitations) explicitly connects Lindquist et al.’s core-affect construct to predictive coding (Bar, Friston) — proposing that unexpected interoceptive sensations are intrinsically motivating because the nervous system’s function is error-reduction, and that precision/gain control (Feldman & Friston 2010) implements attention over prediction-error units. Written four years before Seth & Friston (2016) formalized exactly this move for interoception, it is an early, independent bridge between the constructionist and predictive-coding literatures represented in this wiki.
