Effectiveness of Digital Dispersion Compensation in OCT

Posted by dbos March 4, 2025March 19, 2025Hopkins

Kavli Affiliate: Xingde Li | Authors: Fengquan Liu and Xingde Li | Summary: Dispersion mismatch in optical coherence tomography (OCT) is typically addressed through either physical or digital compensation. In this study, we investigate the impact of dispersion on OCT detection sensitivity and compare the effectiveness of physical and digital compensation across varying degrees of […]

Differential glutamatergic and GABAergic responses drive divergent prefrontal cortex neural outcomes to low and high frequency stimulation

Posted by dbos March 4, 2025March 19, 2025UCSD / Salk

Kavli Affiliate: Jyoti Mishra and Dhakshin Ramanathan | Authors: Morteza Salimi, Milad Nazari, Jonathan Mishler, Mishra Jyoti and Dhakshin Ramanathan | Summary: Background Repetitive brain stimulation is hypothesized to bidirectionally modulate excitability, with low-frequency trains decreasing and high-frequency (>5 Hz) trains increasing activity. Most insights on the neuroplastic effects of repetitive stimulation protocols stem from […]
