“…Facial expressions in humans depend on 17 facial muscle pairs that we share fully with great apes and partially with some other species (Box 2). The neural control of these muscles depends on a network of cortical and subcortical structures with neuroanatomical and functional specialization [1]. For instance, the medial subdivision of the facial nucleus, which moves our ears, is relatively underdeveloped in humans compared to mammals that can move their ears, whereas the lateral subdivision, which moves our mouth, is exceptionally well developed [2].…”

Historically, research on emotion perception has focused on facial expressions, and findings from this modality have come to dominate our thinking about other modalities. Here, we examine emotion perception through a wider lens by comparing facial with vocal and tactile processing. We review stimulus characteristics and ensuing behavioral and brain responses, and show that audition and touch do not simply duplicate visual mechanisms. Each modality provides a distinct input channel and engages partly non-overlapping neuroanatomical systems with different processing specializations (e.g., specific emotions versus affect). Moreover, processing of signals across the different modalities converges, first into multi- and later into amodal representations that enable holistic emotion judgments.

“…Anatomical, neurological, and pathological studies of humans further support the idea that these particular facial muscle modules are in fact deeply entrenched in the evolution, development, and overall organization of our heads. For instance, studies in humans and nonhuman primates suggest that the innervation of the face is bilaterally controlled for the upper part and mainly contralaterally controlled for the lower part and, accordingly, in humans paralysis of the upper face is often bilateral while of the lower face is often unilateral (Müri, ). This is in line with the facial muscle modularity revealed by our network analyses (Fig.…”

Since the rise of evo-devo (evolutionary developmental biology) in the 1980s, few authors have attempted to combine the increasing knowledge obtained from the study of model organisms and human medicine with data from comparative anatomy and evolutionary biology in order to investigate the links between development, pathology, and macroevolution. Fortunately, this situation is slowly changing, with a renewed interest in evolutionary developmental pathology (evo-devo-path) in the past decades, as evidenced by the idea to publish this special, and very timely, issue on "Developmental Evolution in Biomedical Research." As all of us have recently been involved, independently, in works related in some way or another with evolution and developmental anomalies, we decided to join our different perspectives and backgrounds in the present contribution for this special issue. Specifically, we provide a brief historical account on the study of the links between evolution, development, and pathologies, followed by a review of the recent work done by each of us, and then by a general discussion on the broader developmental and macroevolutionary implications of our studies and works recently done by other authors. Our primary aims are to highlight the strength of studying developmental anomalies within an evolutionary framework to understand morphological diversity and disease by connecting the recent work done by us and others with the research done and broader ideas proposed by authors such as Étienne Geoffroy Saint-Hilaire, Waddington, Goldschmidt, Gould, and Per Alberch, among many others to pave the way for further and much needed work regarding abnormal development and macroevolution.

“…The ACC is a key component of the limbic system, highly connected with other prefrontal areas, motor regions, as well as down-stream brainstem nuclei (Bush et al 2000;Watanabe 2017). Midline motor areas in preSMA and ACC are implicated in the generation of non-voluntary facial expressions (Morecraft et al 2004;Müri 2016;Vrticka et al 2013) and constitute a direct output pathway mediating automatic mimicry to emotional faces and mirror neuron networks with communicative/social functions (Ferrari et al 2013;Gothard 2014;Minxha et al 2017). These regions may also contribute to subjective affect, as shown by electrical stimulation during surgery (Caruana et al 2018).…”

Acknowledgments:We would like to thank Lucas Tamarit for his help with the FACSGen program. Finally, we are grateful to Prof. Karl Friston for his guidance in the DCM analysis. 2 AbstractPerception of emotional expressions in faces relies on the integration of distinct facial features. We used fMRI to examine the role of local and global motion information in facial movements during exposure to novel dynamic face stimuli. We found that synchronous expressions distinctively engaged medial prefrontal areas in the ventral anterior cingulate cortex (vACC), supplementary premotor areas, and bilateral superior frontal gyrus (global temporal-spatial processing). Asynchronous expressions in which one part of the face (e.g., eyes) unfolded before the other (e.g., mouth) activated more the right superior temporal sulcus (STS) and inferior frontal gyrus (local temporal-spatial processing). DCM analysis further showed that processing of asynchronous expression features was associated with a differential information flow, centered on STS, which received direct input from occipital cortex and projected to the amygdala. Moreover, STS and amygdala displayed selective interactions with vACC where the integration of both local and global motion cues (present in synchronous expressions) could take place. These results provide new evidence for a role of both local and global temporal dynamics in emotional expressions, extracted in partly separate brain pathways. Importantly, we show that dynamic expressions with synchronous movement cues may distinctively engage brain areas responsible for motor execution of expressions.
