我们不仅能用耳朵听,也能用我们的皮肤感知声音的世界——基于给受试者听一些音节,同时感受皮肤上气流的冲击,研究者证明,大脑能够整合来自多个感觉通道的信息,构建一幅完整的听觉“画面”。这个研究可谓颠覆了人们对如何感知世界的传统认识。以往我们认为,我们要用眼睛来鉴赏视觉世界,用耳朵来感知听觉世界。视觉信息投射到视网膜上,再经视觉神经传到大脑的视觉皮层。听觉信息则根据频率不同引起耳内结构的震动,将听觉的信息转化为神经信号传导到大脑的听觉皮层。
Not only can we hear with our ears, but we can also perceive the world of sounds with our skin-based on listening to syllables and hearing the impact of air currents on the skin, researchers have demonstrated that the brain can integrate information from multiple sensory channels , To build a complete auditory “picture ”. This research can be subverted to people’s traditional understanding of how to perceive the world. In the past we think that we should use the eyes to appreciate the visual world, with the ear to perceive the auditory world. Visual information projected onto the retina, and then transmitted by the visual nerve to the brain’s visual cortex. Auditory information is based on the frequency of different structures in the ear caused the vibration, the auditory information into neural signals transmitted to the auditory cortex of the brain.
