This study looks at whether a non-invasive brain stimulation technique called iTBS can temporarily change brain activity in healthy adults. Researchers will also measure stress levels and coping strategies to see how they relate to these brain changes. The goal is to better under…

This study compares how people with and without tennis elbow feel pressure pain and how their bodies naturally reduce pain after a cold stimulus. Researchers will measure pain thresholds before, during, and after placing one hand in ice water. The goal is to better understand pai…

This early-stage study is testing a new drug, JPH034, in 40 healthy adults aged 18 to 50. Participants receive either the drug or a placebo to check for side effects and measure how the drug moves through the body. The goal is to gather safety information, not to treat any diseas…
