Models of binaural hearing for sound lateralisation and localisation
… the reasonable predictions made for both lateralisation and localisation of acoustic stimuli, the models developed appear also to be well-suited to the computational evaluation of spatial audio systems.

Vom Tiermodell zum Unterrichtsmodell : zur Entwicklung neurodidaktischer Konzepte vor dem Hintergrund kortikaler und präfrontaler Lateralisation
Diese interdisziplinäre Arbeit gliedert sich in einen neurobiologisch-experimentellen und einen didaktischen Teil, wobei der Schwerpunkt auf letzterem liegt. Die dem neurodidaktischen Konzept zugrunde liegenden allgemeinen Erkenntnisse lauten: Für Lernen und Gedächtnisbildung gibt es kein Zentrum …

An investigation into hemispheric lateralisation of different acoustic rates and its relationship with language ability during infancy
… The aim of this thesis is to investigate the lateralisation of two discrete rates at two stages in infancy. This thesis also aims to investigate how rate lateralisation may be related to concurrent and future language ability. <br/><br/>The studies in this thesis presented two amplitude …

Modulation of lateralised responses to primary affect
… sadness). How this subcortically originating lateralisation manifests into observable behaviour however still remains to be established. This research therefore posits that hemispheric lateralisation may be a modulated process, and aims to explore how this modulation guides the directionality …

The circuit basis of olfactory mate recognition and localisation
… type-specific distance tuning properties and lateralisation ability. Additionally, we found an interneuron that is only activated by contralateral input and is well placed in the circuit to create mutual inhibition between the two sides. We propose that this mechanism underlies improved …

An exploration of pre-attentive visual discrimination using event-related potentials
… modulating attention. Generators and hemispheric lateralisation of visual MMN have been investigated by using pertinent clinical groups. A three stimulus visual oddball paradigm was used to explore the elicitation of visual discrimination components to a change in the orientation of stimuli in the …

Development of A Versatile Multichannel CWNIRS Instrument for Optical Brain-Computer Interface Applications
… tasks in the cerebral cortex, and can identify lateralisation of haemodynamic responses to motor events. The approach taken to extend single channel to multichannel was based on a software-controlled interface. This interface allowed flexibility in the control of individual optodes including …

The good, the bad, the complex: Investigating the behavioural consequences of EEG alpha oscillations in visual detection and selective attention
… by attentional cues. In fact, the cue-related lateralisation of alpha power seems to index some other mechanism that is not directly related to the behaviourally relevant bias. We thus reveal the complexity of the relationship between alpha power fluctuations and behavioural performance in …

Effects of Atomoxetine and Methylphenidate on functional brain activation in Medication-naive children with Attention Deficit Hyperactivity Disorder
… effects.<br/>Their differential prefrontal lateralisation suggests potentially stronger effects of MPH on left-lateralised dopaminergic networks, and of ATX on right-lateralised noradrenergic networks. Their shared effects were not restricted to prefrontal regions or task-positive networks, …

Molecular and Neurochemical Effects of Methylphenidate on the Developing Brain
… a deviation from the common pattern of cerebral lateralisation also contribute to some of the symptoms of ADHD, with under-activation of the right prefrontal and right parietal cortices observed in ADHD patients. The psychostimulant, methylphenidate (MPH) is the preferred drug for the treatment …

Clinical expression of perennial ryegrass (lolitrem-B) intoxication in New Zealand horses : a thesis presented in partial fulfillment of the requirements for the degree of Master of Veterinary Science at Massey University, Manawatu, New Zealand
… limb placement that compensated for the lateralisation of the center of gravity. Results indicate that lolitrem-B may lengthen the peak V latency of BAEP traces. mMEPs also showed a lengthening in take-off latency and peak latency. The frusemide challenge revealed that renal K+ secretion …

Ist der Abbau kognitiver Funktionen im Alter unveränderbar? Modulation von Wortflüssigkeitsleistung und Sprachlateralisation durch transkranielle Gleichstromstimulation (tDCS)
… Dopplersonographie (fTCD) gemessenen Sprachlateralisation bei Patienten mit MCI gesunden, älteren Probanden untersucht. Zweitens stand ein möglicher Zusammenhang zwischen Veränderungen der Wortflüssigkeitsleistung und den gemessenen Lateralisationsindizes im Fokus dieses …

ON-FARM APPLICATION OF PLF TECHNOLOGIES TO DETECT EARLY BEHAVIOURAL AND PHYSIOLOGICAL INDICATORS OF DISEASE AND WELFARE IN PAIR - HOUSED DAIRY CALVES BEFORE WEANING.
… linked to social housing. While no evidence of lateralisation emerged, pair-housed calves exhibited higher absolute eye temperatures, suggesting subtle physiological differences associated with higher arousal states. Whereas lying synchronisation appeared more promising for the assessment of …

Syntax and semantics: Similarities in late positive components
… each hemisphere individually in order to assess lateralisation patterns. The results showed that participants of differing familial sinistrality profiles differed in terms of their hemispheric contributions to processing these sentences. While those with no history of familial sinistrality had a …

Social predispositions and underlying neural mechanisms in chicks (Gallus gallus domesticus)

How animal movement defines behaviour: new insights into the ecology of seabirds at sea
… angle of roll, it did not affect the observed lateralisation in individuals. I conclude with a general discussion summarising my main findings and suggesting future research opportunities. This thesis highlights how investigating animal behaviour using movement data can provide new insights …

Exploring the role of molecular imaging in the diagnosis and management of primary adrenocortical disease
… (AVS) remains the current gold standard for lateralisation (i.e. determining whether one or both adrenal glands are implicated). However, it is limited by its invasive nature and the requirement for an experienced interventional radiologist, given the challenges associated with successfully …

Dysregulation of connexin-43 (cx43) in doxorubicin-induced cardiotoxicity
… Cx43 expression in the left ventricle, with lateralisation of Cx43 in ventricular cardiomyocytes. Further investigation of these effects was explored using human 3D cardiac spheroids comprising HUVECs, hCFs, and iCell cardiomyocytes. Unlike the monolayer studies, Cx43 expression levels were …

Electrophysiological systems underlying human domain-general cognition and selective attention
