“…Theoretically, neural lateralization would improve information processing efficiency by providing specialized analysis within each hemisphere, thereby enhancing the ability of land vertebrates to make critical decisions related to mating or feeding in dangerous environments (Rogers et al, 2004). Our behavioral and electrophysiological studies of the lateralization of auditory perception in anurans provides experimental evidence in support of the idea that hemispheric asymmetry in processing cues related to complex perception originated at an early stage in vertebrate evolution (Ocklenburg et al, 2013;Vallortigara, 2000;Vallortigara et al, 1999).…”

Behavioral and neurophysiological studies support the idea that right ear advantage (REA) exists for perception of conspecific vocal signals in birds and mammals. Nevertheless, few studies have focused on anuran species that typically communicate through vocalization. The present study examined the direction and latencies of orientation behaviors in Emei music frogs (Babina daunchina) produced in response to six auditory stimuli emitted by a speaker placed directly behind the subjects. The stimuli included male advertisement calls produced from within burrow nests, which have been shown to be highly sexually attractive (HSA), calls produced from outside burrows, which are of low sexual attractiveness (LSA), screech calls produced when frogs are attacked by snakes, white noise, thunder and silence. For all sound stimuli except the screech, the frogs preferentially turned to the right. Right ear preference was strongest for HSA calls. For the screech and thunder stimuli, there was an increased tendency for subjects to move further from the speaker rather than turning. These results support the idea that in anurans, right ear preference is associated with perception of positive or neutral signals such as the conspecific advertisement call and white noise, while a left ear preference is associated with perception of negative signals such as predatory attack.

“…Hemispheric asymmetries, i.e., functional and structural differences between the left and the right brain hemisphere, affect behaviour and cognition in all vertebrate classes [1][2][3][4][5]. One of the least well understood asymmetric systems is the one that supports emotion processing [6][7][8].…”

Hemispheric asymmetries are a major organizational principle in human emotion processing, but their interaction with prefrontal control processes is not well understood. To this end, we determined whether hemispheric differences in response inhibition depend on the emotional valence of the stimulus being inhibited. Participants completed a lateralised Go/Nogo task, in which Nogo stimuli were neutral or emotional (either positive or negative) images, while Go stimuli were scrambled versions of the same pictures. We recorded the N2 and P3 event-related potential (ERP) components, two common electrophysiological measures of response inhibition processes. Behaviourally, participants were more accurate in withholding responses to emotional than to neutral stimuli. Electrophysiologically, Nogo-P3 responses were greater for emotional than for neutral stimuli, an effect driven primarily by an enhanced response to positive images. Hemispheric asymmetries were also observed, with greater Nogo-P3 following left versus right visual field stimuli. However, the visual field effect did not interact with emotion. We therefore find no evidence that emotion-related asymmetries affect response inhibition processes.

“…Thus, the increased circling in females was probably a direct consequence of increased glucocorticoid release and the increase in circling directed to the left is likely related to brain lateralization. Brain lateralization is a central tenant in neuroscience that states that the two brain hemispheres are specialized to control different tasks (Csermely & Regolin 2012 (Ocklenburg & Gunturkun 2012, Ocklenburg, et al 2013, Rogers 2010. Lateralization is influenced by stress.…”

Noise is an important source of stress that is able to impact negatively on animals' welfare.Anthropogenic activities are a major contributor to noise, and their cumulative effects on individuals could have consequences for wildlife populations. Although transportation noise impacts have been evaluated for vocal and charismatic animals, research regarding the effects of other types of anthropogenic noise on non-charismatic animals has not been undertaken. This research explored the effects of mining noise, which is prevalent in the Australian soundscape, on wild mice (Mus musculus) and Eastern blue tongued lizards (Tiliqua scincoides). The first experimental stage focused on developing a reliable methodology to assess behavioural responses in the blue tongued lizard, and suitable noise exposure and acoustic processing techniques for subsequent experimentation. This was achieved through the analysis of the effects of typical transport stressors on lizards' behaviour. Lizards were exposed to Heat (35 o C), Cold (15 o C), high or low frequency noise or a Control treatment with no stimulus in a test chamber for a 5 s. The test chamber was connected to an escape chamber, accessible after exposure to the stimulus, and a small hiding chamber opposite the test chamber. Lizard behaviour was monitored during stimulus exposure and then for a further 15 minutes, after which each lizard was removed. Lizards exposed to Cold spent less time in the test chamber and more time inactive in the escape chamber. They also spent longer walking towards the hiding chamber both away from the wall and by the wall and walking in the hiding chamber away from the stimulus. Thus, cold temperatures were noxious for lizards in a simulated transport environment as they reduced activity and increased escape attempts.In a second experiment, noise exposure was studied in more detail and the behaviour of blue tongued lizards when exposed to five combinations of mining machinery noise was evaluated.Lizards were exposed to low and high frequencies (≤ or > 2 kHz) at both low (60-65 dB (A)) and high (70-75 dB (A)) amplitudes, and a Control treatment, following the same exposure technique developed in the first experiment. In the test chamber lizards exposed to any mining machinery noise, but especially high frequencies, spent more time freezing, a typical stress response in reptiles, when compared with animals in the Control treatment. In the hiding chamber, high frequencies at high amplitudes decreased durations of the head being held to the right face downwards, suggesting a lateralized fear reaction. High frequency, high amplitude noise was the most detrimental. Mining noise had negative effects on the lizards' behavior and welfare. To estimate mining machinery noise effects on the second animal model, wild mice, amplitudes and frequencies were tested separately to differentiate between these two important components of noise. Using the high and low amplitudes previously established, wild mice were exposed to 3 weeks of continuous noise. Effe...
