Joy Laughter

Joy laughter refers to the emotional experience of joy and its observable expression through laughter, behaviors that communicate positive affect and support psychological well-being. In psychology, joyful experiences engage brain reward systems, while laughter coordinates facial movements, vocalization, breathing, and social cues that can strengthen interpersonal connection. Studying joy and laughter helps researchers examine emotion regulation, social bonding, stress responses, and the role of positive experiences in mental health. These behaviors are also relevant to psychotherapy, developmental research, and investigations of how shared humor and positive emotion influence relationships and resilience.

Empathy is often confused with pity and sympathy, which are different reactions to the situation of someone else or others. Pity is simply an...

2014

The ability to isolate heart valve endothelial cells (VECs) is critical for understanding mechanisms of valve development, maintenance, and disease. Here we describe the isolation of VECs from embryonic and adult Tie2-GFP mice using FACS that will allow for studies determining the contribution of VECs in developmental and disease processes.
