All 13 categories as defined for analysis

Category	Papers	Subjects	Experiments	Included paradigms
Emotion	83	1,383	195	All paradigms that elicited emotion in the subjects such as induction, imagination or recall of own happiness, fear, anxiety, anger, sadness, or disgust
Empathy	46	657	120	All paradigms in which the subjects had to judge emotions in faces or attend to pain in others. This thus involved feeling with the emotions in others, not the more cognitive aspects of “theory of mind”
Olfaction	12	175	31	All olfactory stimuli, no stimuli that elicited trigeminal afferents, no gustatory stimuli
Gustation	13	162	31	All gustatory tasks. Subjects had to taste tastants compared to a tasteless baseline. No odors
Interoception	43	638	105	All visceral sensation, hunger/thirst, sexual arousal, air hunger, changing core temperature or urge to void
Pain	46	573	79	All painful stimuli applied to subjects by temperature, electrical or physical stimulation or hypersensitation. Pain was applied to different parts of the subject’s body
Somatosensation	34	421	46	All somatosensation, no painful or visceral stimuli. Again, different modalities and bodyparts
Motion	64	731	125	All motor tasks, including movement of face, mouth and tongue, and hands/feet irrespective of side
Attention	125	1,918	264	Spatial attention, sorting/matching, Stroop/Flanker/Simon/gonogo/Switching tasks, cues
Language	129	1,704	297	Semantic, syntactic, phonological, orthographic decisions and listening to language
Speech	51	709	130	All motor speech
Working memory	96	1,537	213	All short term memory, working memory, n-back tasks, encoding, and recall
Memory	69	1,188	131	Memory tasks, recall of information learned previous to the experiment
Sum	811	11,796	1,768
