Laser speckle contrast imaging (LSCI) has classically been used to image regional blood flow changes in animal models. In this paper, we demonstrate the use of LSCI for elucidating blood flow characteristics in individual microvessels with diameters as small as 24μm. We extracted profiles of speckle contrast values within individual vessels, both along their diameters and along their lengths and inferred...
Various rehabilitation systems have been developed to deliver therapy for hemiplegic patients. Fugl- Meyer scale and Motor Power Score were common used methods to evaluate training effect and validate the developed systems. However, these assessments were involved with some inevitable subjective factors of therapists. In order to objectively evaluate the effect of a bimanual training that performed...
The bio-imaging techniques have widespread applications from diagnosing diseases to investigating the body tissues at the cells level. Traditionally, these techniques were used mainly in the orthopedic treatment. However, with the development of infrared cameras, ultrasound, and radio wave technology, they are used in different medical fields such as cardiovascular analysis, neurological treatment...
Imaging in awake, behaving animals is an emerging field that offers the advantage of being able to study physiological processes and structures in a more natural state than what is possible in tissue slices or even in anesthetized animals. To date, most imaging in awake animals has used optical fiber bundles or electrical cables to transfer signals to traditional imaging-system components. However,...
Infrared neural stimulation (INS) is well characterized for the peripheral nervous system; however, translation to the central nervous system (CNS) presents a new set of challenges which require us to consider different anatomy, multiple cell types, and the physiology associated with structures in the CNS. This study presents our first attempt to translate INS to in vivo stimulation of the CNS and...
Brain's functional response can be studied by observing the spatiotemporal dynamics of functional and structural changes in cerebral vasculature. However, very few studies explore detailed changes at the level of individual microvessels while revealing the simultaneous wide field view of microcirculation responses to functional stimulation. Here we use a high spatiotemporal resolution laser speckle...
