Pulsed near-infrared radiation has been proposed as an alternative stimulus for auditory nerve stimulation and could be potentially used in the design of cochlear implant. Although the infrared with high absorption coefficient of water (i.e., wavelength ranged from 1.8 to 2.2 μm) has been widely investigated, the lymph in the cochlea absorbs most of the(More)
To explore the penetration depth with short-wavelength infrared light, 980 nm pulse infrared light was used to stimulate the primary motor cortex of rat. The heating model was created to simulate the temperature distribution for 1875 nm and 980 nm infrared neural stimulation. Post-stimulus time histogram was used to observe the neural response induced by(More)
Although infrared laser was proven to be an alternative approach for neural stimulation, there is very little known about the neural response to infrared laser irradiation in visual cortex. This study is to investigate the effect of near-infrared laser irradiation on neural activities at the cortex level. A 850-nm pigtailed diode laser was applied to(More)
Muscle Co-activation (MCo) is the simultaneous muscular activation of agonist and antagonist muscle groups, which provides adequate joint stability, movement accuracy during movement. Infant crawling is an important stage of motor function development that manifests non-synchronization growth and development of upper and lower limbs due to the well-known(More)
To explore whether the short wavelength near infrared laser can stimulate the functional hair cells, pulsed laser with wavelength of 808-nm was used to stimulate guinea pigs cochlea. Compound action potential (CAP) and auditory brainstem responses (ABR) were recorded during the experiments. We successfully recorded photomechanical responses from normal(More)
Multitendoned extrinsic muscles of the human hand can be divided into several neuromuscular compartments (NMCs), each of which contributes to the ability of human finger to produce independent finger movements or force. The aim of this study was to investigate the changes in the spatial activation of flexor digitorum superficialis (FDS) during the fingertip(More)
To explore the optical neural stimulation with visible light, 620-nm red light pulse emitted by LED was used to stimulate the left primary visual cortex of adult rat. The neural response in right primary visual cortex was recorded with a flexible microelectrode. By synchronized averaging the raw signal, optical evoked potentials (OEPs) were observed a(More)
Visual field is one of the important visual functions; it is the extent of the visual field defect that can be employed in judging whether the visual function is impaired. The rapid achievements in computer technologies do provide an impulse for improvement of visual field detection, making possible the automatic, rapid, accurate, detailed and large-scaled(More)
