TAP reading note: Enhanced emotional reactivity after selective REM sleep deprivation in humans: an fMRI study
Selective REM interruption was followed by increased emotional reactivity and a later rebound in REM percentage. This illustrates stage-specific rebound; it does not establish that extra total sleep completes emotional recovery.

What the study found
Selective REM interruption was followed by increased emotional reactivity and a later rebound in REM percentage. This illustrates stage-specific rebound; it does not establish that extra total sleep completes emotional recovery.
Scope & limitations
20 healthy men assigned to REM deprivation or NREM interruptions; imaging analyses used 19.
Small, male-only laboratory sample; repeated stimuli and differences between sleep manipulations limit generalisation. The study does not validate consumer-device REM estimates.
Population & sample
20 healthy men assigned to REM deprivation or NREM interruptions; imaging analyses used 19.
Exposure or intervention
Awakenings at REM onset versus NREM interruptions; baseline, deprivation and recovery sleep.
Outcomes
Polysomnography, emotional responses and fMRI.
Time frame
An acute laboratory sleep-manipulation protocol.
Research funding
CONACYT project 50709 and graduate/postdoctoral grant 86800; hospital fMRI facilities acknowledged.
Research conflicts of interest
Authors declared no commercial or financial relationships constituting a potential conflict.
Reading scope
Publisher HTML: design, sleep results, limitations and declarations; no reanalysis of neuroimaging data.
