According to a new study published in the journal Science, the eye movement characteristics that provide fast eye sleep (brake) name represent a shift in the world of sleeping rats. These findings reveal the reading that can be observed about the internal direction in a dream state. They also provide valuable new insights about the cognitive process of sleeping brain.
Sleeping brakes are often associated with dreaming. Therefore, some have proposed that the nature of brake eye movements can be related to sustainable dream content. Others have suggested that fast eye movements actually reflect the activity of random brain stem. Testing this hypothesis remains a challenge.
Many previous studies rely on reporting subjective dreams and have the potential to be inaccurate by humans. Conversely, Yuta Senzai and Massimo Scanziani focus on the mouse head direction system as an objective reading. When I wake up, HD cell activity in the thalamus rat encodes the direction of the head of the animal when exploring or navigating the environment. Changes in HD cell activity are
Often accompanied by eye movements such as fast saccade in the same direction.
Senzai and Scanziani recorded HC cell activity using extracellular linear probes. They simultaneously monitor the movements of both eyes with a camera mounted on the heads in rats that wake up and sleep. They found that the direction and amplitude of fast eye movements during the sleep brakes that were coded and the amplitude of the rat title in their dream environment.
The findings show that the fast eye movement provides an external reading of the internal cognitive processes that occur during brake sleep and express coordination that can underlie the experience of a realistic and clear dream. “If the eye movements that quickly reflect the mind during sleep, read the movements of others, while observing them sleeping, will open a window to read and potentially manipulate their minds during dreams,” wrote Chris de Zeeuw and Cathrin Canto in the related perspective. For more about this research, see when our eyes move during sleep brakes, we see things in the world of dreams.
