“…This area of activation included primary and secondary auditory cortices (Brodmann areas 41 and 42) and extended into middle temporal cortices in both hemispheres. Combined with consistent results from recent ERP (Störmer et al, 2009) and neuroimaging (Wu et al, 2007) studies, this result shows that shifting attention to a spatial location in preparation for an expected auditory target leads to anticipatory pretarget biasing within auditory cortices. Third, the timing and sequence of attention-control activity in frontal and parietal regions were nearly identical to those found in a recent EEG study of visuospatial attention using similar methods .…”

“…Regardless of sensory modality, attentioncontrol activities were observed in both inferior and superior regions of the parietal and frontal cortices. Previous PET and fMRI studies have implicated these frontoparietal regions in the voluntary control of attention in vision (Corbetta et al, 2000;Corbetta and Shulman, 2002;Macaluso et al, 2003;Serences and Yantis, 2006), audition (Shomstein and Yantis, 2006;Wu et al, 2007;Salmi et al, 2009), and touch (Macaluso et al, 2002(Macaluso et al, , 2003, and in shifting attention between the visual and auditory modalities (modality selection) (Shomstein and Yantis, 2004). The similarities across modalities and tasks suggest that these frontal and parietal regions may perform general attention operations that are modality independent.…”

“…This enhancement of perception and performance is thought to be the end result of control operations performed by a network of frontal and parietal regions that modulates the transmission of information in sensory-specific pathways. Functional neuroimaging methods, such as fMRI, have been used to identify the cortical regions involved in controlling voluntary shifts of attention in visual space (Corbetta and Shulman, 2002;Corbetta et al, 2008) and auditory space (Wu et al, 2007), and there appears to be some overlap in the neural architecture of the visual and auditory attention-control networks (Salmi et al, 2007). The activation of similar brain structures in auditory and visual tasks might indicate that a single, supramodal attention-control network mediates the transmission of information within each modality-specific sensory pathway (Ward et al, 1998;Wright and Ward, 2008).…”

Previous attempts to investigate the supramodal nature of attentional control have focused primarily on identifying neuroanatomical overlap in the frontoparietal systems activated during voluntary shifts of spatial attention in different sensory modalities. However, the activation of the same neural structures is insufficient evidence for a supramodal system, as the same brain regions could interact with one another in very different ways during shifts of attention in different modalities. Thus, to explore the similarity of the functional networks, it is necessary to identify the neural structures involved and to examine the timing and sequence of activities within the network. To this end, we used an electrical neuroimaging technique to localize the neural sources of electroencephalographic signals recorded from human subjects during audiospatial shifts of attention and to examine the timing and sequence of activities within several regions of interest. We then compared the results to an analogous study of visuospatial attention shifts. Similar frontal and parietal regions were activated during visual and auditory shifts of attention, and the timing of activities within these regions was nearly identical. Following this modality-independent sequence of attention-control activity, activity in the relevant sensory cortex was enhanced in anticipation of the response-relevant target. These results are consistent with the hypothesis that a single supramodal network of frontal and parietal regions mediates voluntary shifts of spatial attention and controls the flow of sensory information in modality-specific sensory pathways.

“…However, it is unclear whether the same frontoparietal regions are recruited for both auditory and visual tasks. Several studies have reported activity in a dorsal frontoparietal network that overlaps with the visual system during auditory stimulus anticipation, processing and attention shifts [Bharadwaj et al, 2014; Downar et al, 2000; Krumbholz et al, 2009; Langner et al, 2011; Lee et al, 2012; Linden et al, 1999; Mayer et al, 2006; Shomstein and Yantis, 2004; Watkins et al, 2007; Wu et al, 2007]. In contrast, there is increasing evidence that visual and auditory attention are subserved by different networks [Braga et al, 2013b; Bushara et al, 1999; Degerman et al, 2006; Kong et al, 2014; Maeder et al, 2001; Salmi et al, 2007; Seydell‐Greenwald et al, 2014].…”

A frontoparietal network of brain regions is often implicated in both auditory and visual information processing. Although it is possible that the same set of multimodal regions subserves both modalities, there is increasing evidence that there is a differentiation of sensory function within frontoparietal cortex. Magnetic resonance imaging (MRI) in humans was used to investigate whether different frontoparietal regions showed intrinsic biases in connectivity with visual or auditory modalities. Structural connectivity was assessed with diffusion tractography and functional connectivity was tested using functional MRI. A dorsal–ventral gradient of function was observed, where connectivity with visual cortex dominates dorsal frontal and parietal connections, while connectivity with auditory cortex dominates ventral frontal and parietal regions. A gradient was also observed along the posterior–anterior axis, although in opposite directions in prefrontal and parietal cortices. The results suggest that the location of neural activity within frontoparietal cortex may be influenced by these intrinsic biases toward visual and auditory processing. Thus, the location of activity in frontoparietal cortex may be influenced as much by stimulus modality as the cognitive demands of a task. It was concluded that stimulus modality was spatially encoded throughout frontal and parietal cortices, and was speculated that such an arrangement allows for top–down modulation of modality‐specific information to occur within higher‐order cortex. This could provide a potentially faster and more efficient pathway by which top–down selection between sensory modalities could occur, by constraining modulations to within frontal and parietal regions, rather than long‐range connections to sensory cortices.

“…In the context of visual and auditory stimuli, the posterior parietal cortex is believed to synchronise the spiking activity in those neurons processing the attended stimulus enabling more effective attentional competition reflected by increased activity of the anterior insular cortex (Liu et al, 2003;Wu et al, 2007).…”

After reviewing the literature on current knowledge about consciousness in humans, we present a state-of-the art discussion on consciousness and related key concepts in animals. Obviously much fewer publications are available on non-human species than on humans, most of them relating to laboratory or wild animal species, and only few to livestock species. Human consciousness is by definition subjective and private. Animal consciousness is usually assessed through behavioural performance. Behaviour involves a wide array of cognitive processes that have to be assessed separately using specific experimental protocols. Accordingly, several processes indicative of the presence of consciousness are discussed: perception and cognition, awareness of the bodily-self, selfrelated knowledge of the environment (including social environment). When available, specific examples are given in livestock species. Next, we review the existing evidence regarding neuronal correlates of consciousness, and emphasize the difficulty of linking aspects of consciousness to specific neural structures across the phyla because high-level cognitive abilities may have evolved independently along evolution. Several mammalian brain structures (cortex and midbrain) are involved in the manifestations of consciousness, while the equivalent functional structures for birds and fishes would likely be the pallium/tectum and midbrain. Caution is required before excluding consciousness in species not having the same brain structures as the mammalian ones as different neural architectures may mediate comparable processes. Finally, specific neurophysiological mechanisms appear to be strongly linked to the emergence of consciousness, namely neural synchrony and neural feedback. Considering the limited amount of data available and the few animal species studied so far, we conclude that different manifestations of consciousness can be observed in animals but that further refinement is still needed to characterize their level and content in each species. Further research is required to clarify these issues, especially in livestock species.
