Linking brain structure and activation in temporoparietal junction to explain the neurobiology of human altruism


Morishima, Yosuke; Schunk, Daniel; Bruhin, Adrian; Ruff, Christian C; Fehr, Ernst (2012). Linking brain structure and activation in temporoparietal junction to explain the neurobiology of human altruism. Neuron, 75(1):73-79.

Abstract

Human altruism shaped our evolutionary history and pervades social and political life. There are,however, enormous individual differences in altruism. Some people are almost completely selfish,while others display strong altruism, and the factors behind this heterogeneity are only poorlyunderstood. We examine the neuroanatomical basis of these differences with voxel-basedmorphometry and show that gray matter (GM) volume in the right temporoparietal junction (TPJ)is strongly associated with both individuals' altruism and the individual-specific conditions underwhich this brain region is recruited during altruistic decision making. Thus, individual differencesin GM volume in TPJ not only translate into individual differences in the general propensity tobehave altruistically, but they also create a link between brain structure and brain function byindicating the conditions under which indi

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
