Laughter has a major role in daily social interactions; consequently, its biologic bases have been previously studied. Nevertheless, its cerebral representation remains unclear. The most accepted hypothesis has postulated that laughter has 2 components: mirth, related to the temporal and frontal neocortical areas, and motor aspect, related to the limbic system and brainstem. ⋯ In conclusion, these findings support the anatomic subdivision of the laughter's mechanism and the role of the cingulum in its motor component. Furthermore, smiles and laughter could be useful functional landmarks to identify the cingulum during subcortical mapping. Although it remains unclear whether pursuing resection beyond this point would have caused permanent postoperative deficits, considering laughter's role in social interaction and other emotion-processing functions associated with the cingulum, in the future it could be potentially considered a functional limit of the resection of intrinsic tumors.

Modern-day care of the neurosurgery patient has grown increasingly complex and typically involves a variety of medical team members. Proper communication and transmission of clinical data within the neurosurgery team is required for successful outcomes, especially within the operating room. ⋯ Although most physicians would agree that communication between all these stakeholders should improve, certain barriers are present, including the adoption of newer technologies and the lack of formal training. In this article, we review current and projected trends relating to the enhancement of neurosurgical communication at all levels.
