“…They can also recognize different human faces and show inversion effects, although they take longer to learn to discriminate between them (Kendrick et al 1996). Under freeviewing conditions, Peirce et al (2000) found evidence for a left visual-field bias (right-hemisphere advantage) for familiar, but not unfamiliar, sheep faces using a series of experiments using chimeric face composites, an effect also found in human face processing. Interestingly, sheep did not show this visual-field bias for human faces (Peirce et al 2001) suggesting that there is an expertise and familiarity requirement for developing a right brain hemisphere advantage.…”

“…By contrast, the view-dependent cells tend to show a reduced magnitude of response not only to inversion and view, but also to whether the eyes are visible, or the external or internal face features are removed, or which half of the face is viewed (figure 3). It is these latter types of manipulations which impair behavioural discrimination of faces (Kendrick et al 1995(Kendrick et al , 1996Peirce et al 2000) and so a reasonable hypothesis is that it is the cells in the network which show view-dependent tuning that are used primarily for accurate and rapid identification of faces, at least in the first instance. The view-independent ones may be of more importance for maintaining recognition as the individual being viewed moves and, as we will discuss in a moment, possibly for the formation of face imagery.…”

Visual cues from faces provide important social information relating to individual identity, sexual attraction and emotional state. Behavioural and neurophysiological studies on both monkeys and sheep have shown that specialized skills and neural systems for processing these complex cues to guide behaviour have evolved in a number of mammals and are not present exclusively in humans. Indeed, there are remarkable similarities in the ways that faces are processed by the brain in humans and other mammalian species. While human studies with brain imaging and gross neurophysiological recording approaches have revealed global aspects of the face-processing network, they cannot investigate how information is encoded by specific neural networks. Single neuron electrophysiological recording approaches in both monkeys and sheep have, however, provided some insights into the neural encoding principles involved and, particularly, the presence of a remarkable degree of high-level encoding even at the level of a specific face. Recent developments that allow simultaneous recordings to be made from many hundreds of individual neurons are also beginning to reveal evidence for global aspects of a population-based code. This review will summarize what we have learned so far from these animalbased studies about the way the mammalian brain processes the faces and the emotions they can communicate, as well as associated capacities such as how identity and emotion cues are dissociated and how face imagery might be generated. It will also try to highlight what questions and advances in knowledge still challenge us in order to provide a complete understanding of just how brain networks perform this complex and important social recognition task.

“…This conclusion might be surprising as similar capacities are thought to require specialized neural circuits and extensive experience in humans and mammals in general [90][91][92][93][94][95][96]. However, these performances are possible with reduced computational resources, as suggested by analyses with artificial neural networks [97], in particular if the brain possesses the flexibility to allocate resources towards the analysis of local or global cues through top-down processing to accommodate various contexts.…”

The forest or the trees: preference for global over local image processing is reversed by prior experience in honeybees

et al. 2015

Traditional models of insect vision have assumed that insects are only capable of low-level analysis of local cues and are incapable of global, holistic perception. However, recent studies on honeybee (Apis mellifera) vision have refuted this view by showing that this insect also processes complex visual information by using spatial configurations or relational rules. In the light of these findings, we asked whether bees prioritize global configurations or local cues by setting these two levels of image analysis in competition. We trained individual freeflying honeybees to discriminate hierarchical visual stimuli within a Y-maze and tested bees with novel stimuli in which local and/or global cues were manipulated. We demonstrate that even when local information is accessible, bees prefer global information, thus relying mainly on the object's spatial configuration rather than on elemental, local information. This preference can be reversed if bees are pre-trained to discriminate isolated local cues. In this case, bees prefer the hierarchical stimuli with the local elements previously primed even if they build an incorrect global configuration. Pre-training with local cues induces a generic attentional bias towards any local elements as local information is prioritized in the test, even if the local cues used in the test are different from the pre-trained ones. Our results thus underline the plasticity of visual processing in insects and provide new insights for the comparative analysis of visual recognition in humans and animals.

“…A right-hemisphere bias has also been documented for social responses in a number of species of fishes (Sovrano et al 2001), chicks ( Vallortigara & Andrew 1994), sheep ( Peirce et al 2000) and monkeys (Vermeire et al 1998), and may relate to the righthemispheric involvement in social understanding in humans (e.g. Sperry et al 1979).…”

Handedness and cerebral asymmetry are commonly assumed to be uniquely human, and even defining characteristics of our species. This is increasingly refuted by the evidence of behavioural asymmetries in non-human species. Although complex manual skill and language are indeed unique to our species and are represented asymmetrically in the brain, some non-human asymmetries appear to be precursors, and others are shared between humans and non-humans. In all behavioural and cerebral asymmetries so far investigated, a minority of individuals reverse or negate the dominant asymmetry, suggesting that such asymmetries are best understood in the context of the overriding bilateral symmetry of the brain and body, and a trade-off between the relative advantages and disadvantages of symmetry and asymmetry. Genetic models of handedness, for example, typically postulate a gene with two alleles, one disposing towards right-handedness and the other imposing no directional influence. There is as yet no convincing evidence as to the location of this putative gene, suggesting that several genes may be involved, or that the gene may be monomorphic with variations due to environmental or epigenetic influences. Nevertheless, it is suggested that, in behavioural, neurological and evolutionary terms, it may be more profitable to examine the degree rather than the direction of asymmetry.
