This June in JoVE, we focus on a few surgical procedures. First up, we take a look at two articles dealing with cornea excision and preparation for transplant. Together, two groups of authors, from Italy and Michigan , have documented the steps for removing the entire cornea from the eye and isolating the posterior layer for endothelial keratoplasty, a process that decreases the risk of infection or graft rejection and improves the patient’s ability to see.
In JoVE Neuroscience, we look at new research applications of electrocorticography, (ECoG),a surgical procedure that identifies the neuronal centers that cause epilepsy. The procedure typically helps clinicians map regions that need to be spared during resective surgery. This article instead shows recording of brain activity in the high gamma frequency range, during simple cognitive, or motor tasks. Then, the video article demonstrates how to use the SIGFRIED software system to perform rapid, real-time functional mapping based on ECoG signals.
In JoVE Bioengineering, scientists reproduce microvasculature on a microfluidic “chip” lined with endothelial cells. This device allows scientists to study, in vitro, a controlled microenvironment that can be used to study hemodynamic processes as well as hematologic disease.
