Title Induced abortion and social factors in wild horses Type (up) Journal Article
Year 1983 Publication Nature Abbreviated Journal Nature
Volume 303 Issue 5912 Pages 59-61
Keywords Abortion, Induced/*veterinary; Abortion, Veterinary/*etiology; Aggression/physiology; Animals; Evolution; Female; Horses/*physiology; Humans; Pregnancy; Sexual Behavior, Animal/*physiology
Abstract Much evidence now suggests that the postnatal killing of young in primates and carnivores, and induced abortions in some rodents, are evolved traits exerting strong selective pressures on adult male and female behaviour. Among ungulates it is perplexing that either no species have developed convergent tactics or that these behaviours are not reported, especially as ungulates have social systems similar to those of members of the above groups. Only in captive horses (Equus caballus) has infant killing been reported. It has been estimated that 40,000 wild horses live in remote areas of the Great Basin Desert of North America (US Department of Interior (Bureau of Land Management), unpublished report), where they occur in harems (females and young) defended by males. Here I present evidence that, rather than killing infants directly, invading males induce abortions in females unprotected by their resident stallions and these females are then inseminated by the new males.

Title Teaching in tandem-running ants Type (up) Journal Article
Year 2006 Publication Nature Abbreviated Journal Nature
Volume 439 Issue 7073 Pages 153
Keywords *Animal Communication; Animals; Ants/*physiology; Feedback/physiology; Learning/*physiology; *Teaching
Abstract The ant Temnothorax albipennis uses a technique known as tandem running to lead another ant from the nest to food--with signals between the two ants controlling both the speed and course of the run. Here we analyse the results of this communication and show that tandem running is an example of teaching, to our knowledge the first in a non-human animal, that involves bidirectional feedback between teacher and pupil. This behaviour indicates that it could be the value of information, rather than the constraint of brain size, that has influenced the evolution of teaching.

Title Cognitive neuroscience of human social behaviour Type (up) Journal Article
Year 2003 Publication Nature Reviews. Neuroscience Abbreviated Journal Nat Rev Neurosci
Volume 4 Issue 3 Pages 165-178
Keywords Cognition; Emotions; Humans; Models, Psychological; *Social Behavior
Abstract We are an intensely social species--it has been argued that our social nature defines what makes us human, what makes us conscious or what gave us our large brains. As a new field, the social brain sciences are probing the neural underpinnings of social behaviour and have produced a banquet of data that are both tantalizing and deeply puzzling. We are finding new links between emotion and reason, between action and perception, and between representations of other people and ourselves. No less important are the links that are also being established across disciplines to understand social behaviour, as neuroscientists, social psychologists, anthropologists, ethologists and philosophers forge new collaborations.

Title Neurophysiological mechanisms underlying the understanding and imitation of action Type (up) Journal Article
Year 2001 Publication Nature Reviews Neuroscience Abbreviated Journal Nat Rev Neurosci
Volume 2 Issue 9 Pages 661-670
Keywords
Abstract What are the neural bases of action understanding? Although this capacity could merely involve visual analysis of the action, it has been argued that we actually map this visual information onto its motor representation in our nervous system. Here we discuss evidence for the existence of a system, the ‘mirror system’, that seems to serve this mapping function in primates and humans, and explore its implications for the understanding and imitation of action.

Title Precise auditory-vocal mirroring in neurons for learned vocal communication Type (up) Journal Article
Year 2008 Publication Nature Abbreviated Journal Nature
Volume 451 Issue 7176 Pages 305-310
Keywords
Abstract Brain mechanisms for communication must establish a correspondence between sensory and motor codes used to represent

the signal. One idea is that this correspondence is established at the level of single neurons that are active when the

individual performs a particular gesture or observes a similar gesture performed by another individual. Although neurons

that display a precise auditory–vocal correspondence could facilitate vocal communication, they have yet to be identified.

Here we report that a certain class of neurons in the swamp sparrow forebrain displays a precise auditory–vocal

correspondence. We show that these neurons respond in a temporally precise fashion to auditory presentation of certain

note sequences in this songbird’s repertoire and to similar note sequences in other birds’ songs. These neurons display

nearly identical patterns of activity when the bird sings the same sequence, and disrupting auditory feedback does not alter

this singing-related activity, indicating it is motor in nature. Furthermore, these neurons innervate striatal structures

important for song learning, raising the possibility that singing-related activity in these cells is compared to auditory

feedback to guide vocal learning.
