Why do our eyes move when we're dreaming?
|

Scientists have worked out why your eyes move when you’re dreaming. Scientists have known for decades that the rapid eye movements (REMs) that occur during sleep signal that we’re dreaming, but what do the individual eye motions really represent? It’s long been hypothesised that each movement of the eye reflects new visual information in our dreams, and now for the first time researchers have demonstrated that this is actually the case. According to a new study by researchers at Tel Aviv University in Israel, each flick of the eye that occurs during REM sleep accompanies the introduction of a new image in our dream, with the movement essentially acting like a reset function between individual dream "snapshots".

According to a new study conducted out of Italy, staring into another individuals eyes could induce hallucinogenic effects. The experiment is simple: get two individuals to look into each other's eyes for 10 minutes while they are sitting in a dimly lit room. The sensations that ensue resemble mild "dissociation" - a rather vague psychological term for when people lose their normal connection with reality. It can include feeling like the world is unreal, memory loss and odd perceptual experiences, such as seeing the world in black and white Healthy participants said they'd had "... a compelling experience unlike anything they'd felt before", they scored higher on a dissociative states questionnaire than control participants, and 75 per cent ...

This is the semi-transparent eyelid of the red-eyed tree frog, Agalychnis Callidryas. Frogs aren't the only creatures with 'third eyelids' that keep their eyes moist without blocking vision completely. Sharks, cats, crocodiles, polar bears and camels have them too.

This trick will make your brain see a black-and-white image in color

Watch the video above, the trick is nothing short of incredible! This is due to a mechanism called the opponent-process theory, which was developed in the 1870s. It is the idea of perceiving color in terms of paired opposites such as red with green, and yellow with blue. The possible scientific explanation for this theory is that bipolar cells are excited by one set of wavelengths and inhibited by other, which are in extend attached to the cone retinal receptors.
