The interstitial cells of Cajal (ICC) are the pacemaker cells of the gastrointestinal (GI) tract. They form complex networks between smooth muscle cells and post-ganglionic neuronal fibers to regulate GI contractility. Here, we present immunofluorescence methods cross-sectional and whole-mount visualization of murine ICC networks.

Chronic ocular hypertension is induced using laser photocoagulation of the trabecular meshwork in mouse eyes. The intraocular pressure (IOP) is elevated for several months after laser treatment. The decrease of visual acuity and contrast sensitivity of experimental animals are monitored using the optomotor test.

¹China Rehabilitation Research Center, ²Institute of Rehabilitation Science of China, ³Center of Neural Injury and Repair, Beijing Institute for Brain Disorders, ⁴Beijing Key Laboratory of Neural Injury and Rehabilitation

Here we present a combination of laser Doppler perfusion imaging (LDPI) and laser Doppler perfusion monitoring (LDPM) to measure spinal cord local blood flows and oxygen saturation (SO₂), as well as a standardized procedure for introducing spinal cord trauma on rat.

Investigating the Effect of Different Types of Exercise on Upper Limb Functional Recovery in Patients with Right Hemisphere Damage Based on fNIRS

Yu Wei^*1,2, JiaLi Chen^*3, Rui Fang^*1,2, JingYa Liu^1,2, MengChen Feng^1,2, HuiRong Du², MeiQing Wang², Reziya Abulihaiti², Hua Ling^2,4, FuBiao Huang^1,2

¹Department of Occupational Therapy, China Rehabilitation Research Center, ²Faculty of Rehabilitation, Capital Medical University, ³College of Sports Health, Tianjin Institute of Physical Education, ⁴China Rehabilitation Science Institute

Here, we investigate the effect of functional occupational therapy combined with assisted active or passive motion on the upper limb function of patients with right hemisphere damage and explore the effect of functional near-infrared spectroscopy on brain function remodeling.
