Meditation is an accessible mental practice associated with emotional regulation and well-being. Loving-kindness meditation (LKM) specifically involves focusing one’s attention on thoughts of well-being for oneself and others. (2/10)

Previous findings have revealed increased gamma synchrony during LKM. We leveraged iEEG recordings to test whether those changes occur in the hippocampus and amygdala, critical brain areas involved in emotional regulation. 🧠 (3/10)

We also tested the hypothesis that LKM induces physiological changes from the very first time someone practices it. (4/10)

Patients with treatment resistant epilepsy who were chronically implanted with a responsive #neurostimulation system engaged in LKM in a naturalistic setting optimized for meditative practices. (5/10)

We recorded local field potentials (LFPs) from the amygdala and hippocampus in these patients and parameterized the periodic and aperiodic features of this signal. (6/10)

LKM was associated with an increase in gamma (30-50 Hz) power in both the amygdala and hippocampus. (7/10)
