A sleeping octopus doesn't just go still, its skin flickers through color changes and texture shifts, with twitches recurring every 30 to 40 minutes, a second, more active sleep stage that a later brain-recording study found produces neural activity resembling an awake brain

2+ day, 23+ hour ago   (166+ words) These fleeting episodes of neural activity suggest octopuses may experience a second sleep stage—one that looks suspiciously like dreaming.

A 2024 meta-analysis found a small achievement advantage for handwritten lecture notes, but the headline-making EEG study did not test retention: 36 students copied familiar words by hand or typed them with one finger
