The human brain has evolved specialized neural mechanisms for visual recognition of faces, which afford us a remarkable ability to discriminate between, remember and think about many hundreds of different individuals. Sheep also recognize and are attracted to individual sheep and humans by their faces, as they possess similar specialized neural systems in the temporal and frontal lobes for assisting in this important social task, including a greater involvement of the right brain hemisphere…

Are face recognition abilities in humans and sheep really ‘comparable’?
TLDR
As scientists who study face recognition in humans, Knolle et al .
Functional asymmetry in sheep temporal cortex
TLDR
The data suggest that, while specialised face-sensitive neural circuits in the right hemisphere may play a key role in the rapid identification and discrimination of facial identity, those on the left may be involved more with slower processes associated with integrating the emotional or mnemonic consequences of recognition.
Our Faces in the Dog's Brain: Functional Imaging Reveals Temporal Cortex Activation during Perception of Human Faces
TLDR
The temporal cortex is introduced as a candidate to process human faces, a pillar of social cognition in dogs, and results are consistent with reports in other species like primates and sheep, that suggest a high degree of evolutionary conservation of this pathway for face processing.
Behavioural and neurophysiological evidence for face identity and face emotion processing in animals
TLDR
A review of animal-based studies about the way the mammalian brain processes the faces and the emotions they can communicate and associated capacities such as how identity and emotion cues are dissociated and how face imagery might be generated is summarized.
Sheep recognize familiar and unfamiliar human faces from two-dimensional images
TLDR
Data show that sheep have advanced face-recognition abilities, comparable with those of humans and non-human primates.
Recognition of human face images by the free flying wasp Vespula vulgaris
TLDR
Investigating the visual capacities of the widespread invasive wasp Vespula vulgaris confirms that a general visual system can likely solve complex recognition tasks, the first stage to evolve a visual expertise system to face recognition, even in the absence of neurobiological or behavioral specialization.
Neural Encoding Principles in Face Perception Revealed Using Non-Primate Models
TLDR
This chapter will provide an overview of what the authors know from studies on sheep about the neural substrates involved in face identity and face emotion processing, focusing on electrophysiological studies which have provided evidence for both high-level sparse encoding and also distributed population encoding as well as some differences in responses in left and right hemispheres.
A specialized face-processing model inspired by the organization of monkey face patches explains several face-specific phenomena observed in humans
TLDR
It is shown that a hierarchical computational model, inspired by electrophysiological evidence on face processing in primates, is able to generate representational properties similar to those observed in monkey face patches, and provides insights about the underlying computations that transfer visual information from posterior to anterior face patches.
Rhesus monkeys (Macaca mulatta) lack expertise in face processing.
TLDR
The results support evolutionary differences between rhesus monkeys and Hominoids in the importance of configural cues and their ability to individuate conspecifics' faces, suggesting a lack of face expertise in rhesu monkeys.

Cells in temporal cortex of conscious sheep can respond preferentially to the sight of faces.
TLDR
It is demonstrated that cells that respond preferentially to faces are present in the temporal cortex of a nonprimate species, and that the responses of these cells are influenced by factors relevant to social interaction.
Is right hemisphere specialization for face discrimination specific to humans?
TLDR
The results show that discrimination of upright faces in sheep preferentially engages the right temporal cortex, as it does in humans, and that performance of active choices between such faces may additionally involve the basal amygdala and hippocampus.
Organization and functions of cells responsive to faces in the temporal cortex.
TLDR
The selectivity for view suggests that the neural operations underlying face or head recognition rely on parallel analyses of different characteristic views of the head, the outputs of these view-specific analyses being subsequently combined to support view-independent (object-centred) recognition.
Mothers determine sexual preferences
TLDR
It is shown that the emotional bond between a mother and her male offspring, rather than other social or genetic factors, may irreversibly determine these species' social and sexual preferences.
Imagery neurons in the human brain
TLDR
This study reveals single neuron correlates of volitional visual imagery in humans and suggests a common substrate for the processing of incoming visual information and visual recall.
