Science cannot address the “soul” as a spiritual entity, but it has begun to study what happens to consciousness and brain activity after cardiac arrest. What researchers have found is surprising:
1. Consciousness may last for several minutes after clinical death
Recent studies show that some people who went into cardiac arrest and were resuscitated clearly remember what happened in those minutes.
They describe seeing their bodies from the outside, hearing voices, or feeling deep peace. Scientists now refer to these events as near-death experiences (NDEs).
2. Brain activity after death
Hospital studies have detected bursts of brain activity even minutes after the heartbeat stops. This suggests that consciousness—or at least some form of perception—may persist beyond the point at which a person is declared clinically dead.
A 2023 study published in Resuscitation analyzed cardiac arrest cases and found that some patients showed a “brain signature associated with conscious perception,” indicating that something occurs in the brain that is not yet fully understood.
