An investigation into how multisensory integration is affected by age-related declines in hearing and vision.

多感觉整合（MSI）是将来自不同感觉系统的信息组合在一起以产生准确感知的过程（Stein, Stanford & Rowland, 2009）。MSI被认为发生在大脑的颞上沟（STS）。STS位于颞叶，这是大脑中主要受与衰老相关的体积损失影响的区域。除了脑容量减少，健康衰老还会导致视力和听力下降。与年龄相关的视力下降预计将影响全球20亿人，全球有超过3.6亿人受到与年龄相关的听力损失的影响。尽管这些感觉缺陷和解剖变化在创造准确感知方面起着重要作用，但我们对它们如何影响MSI知之甚少。进一步了解这一领域对于了解感知和认知如何随着年龄的增长而变化以及这种变化对日常生活的影响至关重要。

Multisensory integration (MSI) is the process by which information from different sensorysystems is combined to create an accurate percept (Stein, Stanford & Rowland, 2009). MSI isbelieved to take place in the superior temporal sulcus (STS) of the brain. The STS is located in thetemporal lobe, which is the brain region primarily affected by volume loss associated with ageing. Inaddition to brain volume loss, healthy ageing also causes vision and hearing loss. Age-related3declines in vision are predicted to affect 2 billion people worldwide, and more than 360 millionpeople worldwide are affected by disabling age-related hearing loss. Very little is known about howthese sensory deficits and anatomical changes influence MSI, despite their important role in creatingan accurate percept. Further understanding of this area is vital for informing how perception andcognition changes with ageing, and the impact that such changes have on daily life.
