Discovering The Brain Activation Patterns Associated With Somatosensory Stimulation In The Lower Extremity In Healthy Adults At Rest: Preliminary Results For A Systematic Review, Siying Luan
Undergraduate Student Research Internships Conference
Stroke, which is the leading cause of disability and the third leading cause of death in adults in North America, burdens millions of people as they age. When people experience the long-lasting consequences of stroke, such as limited mobility, the rehabilitation process becomes critical. The mechanism behind walking is supported by a complex system, the somatosensory nervous system. This system transmits information that is essential for one to complete daily tasks, which means the relationship between the somatosensory system and walking is critical to understand for future innovative rehabilitation interventions. Thus, we are investigating the brain activation patterns associated with …

Patient neurological outcomes following cardiac surgery are improved when near-infrared spectroscopy (NIRS) is used to optimize intraoperative cerebral oxygen delivery. However, current NIRS analysis methods have difficulties monitoring adult brains due to contamination from the extracerebral layer (ECL).
The objective of this thesis is to develop a time-resolved (TR) NIRS data analysis method for monitoring adult cerebral oxygen saturation (ScO2) and total hemoglobin (HbT) by assuming the head is composed of two layers – the ECL and the brain. We tested the validity of this assumption using in silico data from an adult human head using two approaches; a few-wavelength, …
