Sleep Characteristics in Blind People

Grace Diana Maddela

Two different sleep states, Non- REM sleep (NREM) and rapid eye movement (REM) sleep, have been described in humans based on electrophysiological parameters. NREM rest is routinely partitioned into 3 phases , which are portrayed by various EEG designs. The third stage is usually portrayed as delta or N3 rest . Moreover, solid action is hypotonic and visual developments are scant or missing. REM rest, conversely, is characterized by EEG initiation, presence of saw tooth waves muscle atonia, and verbose eruptions of quick eye developments. The ordinary human grown-up enters rest through NREM rest. REM rest doesn't happen until 80 min or longer from that point and both rest states substitute consistently during that time with a time of around 90 min.
