“…This view accords with the finding that information within the insect brain is quickly distributed into multiple parallel (and decorrelated) streams for the separate extraction of individual stimulus features [77]. The vertebrate auditory system, in contrast, is a general-purpose and more flexible system that is shaped by learning [78][79][80][81], affected by mood [82], focused by attention [83][84][85], and one that influences and is influenced by other parts of the brain, both sensory [86] and motor [87] areas, to detect and interpret any sound that may be subjectively important at any particular moment. Our auditory system reconfigures its functional connectivity 'on the fly' [88,89].…”

The evolution of hearing in terrestrial animals has resulted in remarkable adaptations enabling exquisitely sensitive sound detection by the ear and sophisticated sound analysis by the brain. In this review, we examine several such characteristics, using examples from insects and vertebrates. We focus on two strong and interdependent forces that have been shaping the auditory systems across taxa: the physical environment of auditory transducers on the small, subcellular scale, and the sensory-ecological environment within which hearing happens, on a larger, evolutionary scale. We briefly discuss acoustical feature selectivity and invariance in the central auditory system, highlighting a major difference between insects and vertebrates as well as a major similarity. Through such comparisons within a sensory ecological framework, we aim to emphasize general principles underlying acute sensitivity to airborne sounds.Introduction Auditory physiology offers a distinctive perspective on the interaction between a sensory system and its environment. On the one hand, auditory systems in vertebrates and insects with sensitive hearing are capable of remarkable performances on multiple levels, both within the sensory periphery where the minute energies associated with sound are converted into electrical signals, as well as within higher-order brain areas where complex natural stimuli such as human speech are processed. For example, displacements caused by acoustical stimuli in the inner ear at the threshold of hearing are sub-nanometer and comparable to the distance between atoms in molecules [1]. Furthermore, thermal fluctuations in the ear's mechanotransduction apparatus not only are significant, but also can be larger than the faintest audible signals, making signal detection a challenging task [2]. Ascending the sensory hierarchy, one encounters other marvels of evolution, such as the ability of individual neurons to encode -using millisecond-long action potentials -inter-aural time differences of only about ten microseconds, and to use this information to localize the source of the sound [3,4]. No engineered system has yet been designed that could understand distorted speech in a noisy and reverberating environment with multiple speakers. That our auditory system achieves this feat is testament to its remarkable performance.On the other hand, an engineer could argue that the auditory system's performance is objectively poor, even in animals with sensitive hearing: at the very first step, during the mechanoelectrical transduction in the inner ear, external sounds are distorted, or even completely suppressed, while new tones are generated by the ear itself [5]. Forward and backward masking, illusory percepts of nonexistent tones (such as the Zwicker illusion [6]), perceptual merging of separate auditory streams, the precedence effect suppressing the perception of echoes that has been demonstrated in insects and vertebrates [7,8] (and which some blind people can unsuppress), auditory hallucinations, and a frustrating inab...

“…Indeed, mood induction may also modulate mismatch responses at the right hemisphere (Schock et al, 2012). Thus, similar to the bidirectional interaction of spatial attention across modalities, bidirectional interaction between spatial attention and negative emotion can be expected.…”

“…Therefore, we chose a paradigm, which has been shown to elicit side-specific responses at the level of the auditory cortices (Hertrich et al, 2002). The auditory stimulation was chosen to match the study in Schock et al (2012), but conducted in an independent sample. Sequences of consonant-vowel (CV) syllables /ba/ and /ka/ were applied dichotically.…”

The auditory mismatch responses are elicited in absence of directed attention but are thought to reflect attention modulating effects. Little is known however, if the deviants in a stream of standards are specifically directing attention across modalities and how they interact with other attention directing signals such as emotions. We applied the well-established paradigm of left- or right-lateralized deviant syllables within a dichotic listening design. In a simple target detection paradigm with lateralized visual stimuli, we hypothesized that responses to visual stimuli would be speeded after ignored auditory deviants on the same side. Moreover, stimuli with negative valence in the visual domain could be expected to reduce this effect due to attention capture for this emotion, resulting in speeded responses to visual stimuli even when attention was directed to the opposite side by the auditory deviant beforehand. Reaction times of 17 subjects confirmed the speeding of responses after deviant events. However, reduced facilitation was observed for positive targets at the left after incongruent deviants, i.e., at the right ear. In particular, significant interactions of valence and visual field and of valence and spatial congruency emerged. Pre-attentive auditory processing may modulate attention in a spatially selective way. However, negative valence processing in the right hemisphere may override this effect. Resource allocation such as spatial attention is regulated dynamically by multimodal and emotion information processing.

In contrast to healthy controls, BD patients did not significantly deviate from the veridical center, regardless which hand was used to bisect horizontal lines. This finding indicates an atypical functional cerebral asymmetry in visuospatial attention in BD euthymia, supporting the idea of a dysfunction especially in the right fronto-parietal cortex.
