Intermittent Theta Burst Stimulation Drives Bi-Directional Changes in Excitability in Prefrontal Cortex

Kavli Affiliate: Jyoti Mishra and Dhakshin Ramanathan | Authors: Morteza Salimi, Milad Nazari, Jonathan Mishler, Jyoti Mishra and Dhakshin Ramanathan | Summary: Summary: Theta burst stimulation (TBS), an FDA-cleared treatment for depression, is hypothesized to modulate excitability in the prefrontal cortex, though this has not definitively been shown in vivo. We performed calcium imaging on […]

Functional Regrowth of Norepinephrine Axons in the Adult Mouse Brain Following Injury

Kavli Affiliate: David Linden | Authors: Patrick R Cooke and David J Linden | Summary: Summary: It is widely believed that axons in the central nervous system of adult mammals do not regrow following injury. This failure is thought, at least in part, to underlie the limited recovery of function following injury to the brain […]
