Abstract:
Perception has traditionally been studied as a modular function where different sensory systems operate as separate and independent modules. However, multisensory integration is essential for the perception of a coherent and unified representation of the external world that we experience phenomenologically. Mounting evidence suggests that the senses do not operate in isolation but that the brain processes and integrates information across modalities. A standing debate is at what level in the processing hierarchy the sensory streams converge, for example, if multisensory speech information conv

Abstract:
Our perception of events depends on the integration of information derived from different sensory modalities. Functional imaging and electrophysiological studies have shown that multisensory interactions occur even at the level of primary sensory cortices; however their functional significance remains elusive. Therefore, to explore the relationship between multisensory interactions in early auditory cortical processing areas and behaviour, we recorded activity from the auditory cortex during the performance of different auditory-visual tasks.

Abstract:
Periodic changes of environmental signals are sufficient to synchronise circadian rhythms across species. Circadian time, then, is a concept tethered to a diverse spread of different sensory modalities. In spite of this fact, circadian systems have historically been studied in a unimodal fashion investigating the processing of singular cues, while keeping others constant. My research sought to challenge this dogma via exploration of multisensory cue combination in the circadian clock of Drosophila melanogaster. Systematic behavioural analysis in wild type flies showed that misalignments betwee

In this sense, perception emerges from the individual activity of distinct sensory modalities, operating as separate modules, but rather from multisensory integration processes.
