It's all about smooth pursuit.
- While lucid dreaming, we use the same eye movement patterns as when we observe physical actions.
- However, we use different eye patterns when we imagine movement.
- Researchers believe this might help add to our understanding of consciousness.
Getty Images<p>To understand smooth pursuit you can <a href="https://blogs.scientificamerican.com/illusion-chasers/what-lucid-dreams-look-like/" target="_blank">try this experiment</a>: Track your index finger, held out at arm's length, from left to right several times. Your eyes follow the pattern in a reliably smooth pattern. On the contrary, when you try to imagine the same exact movement, your eyes will not flow smoothly left to right, but jump ahead to particular points. This is due to your saccadic system, a name derived from the French word for "jolt." In both lucid dreaming and awakened perception, your smooth pursuit system is engaged. </p><p>The researchers write that vividness relies on intensity of neural activation. Imagining images compete with our normal sensory process, but when asleep our sensory input system — absorbing the world around us — is suppressed. External objects that could bombard our perception processes are eliminated. They continue, </p><blockquote>Our findings suggest that, in this respect, the visual imagery that occurs during REM sleep is more similar to perception than imagination. . . . Under conditions of low levels of competing sensory input and high levels of activation in extrastriate visual cortices (conditions associated with REM sleep), the intensity of neural activation underlying the imagery of visual motion (and therefore its vividness) is able to reach levels typically only associated with waking perception.</blockquote>
Just imagining movement fires the same neurons as if we were actually moving. A new study shows we can wake our sleeping mind to practice motor skills in our dreams.
Mental training is arguably as important as physical fitness. That argument is gaining strength as a growing body of literature unravels the once-mysterious connections between consciousness and movement. We know that the murky domain of subconscious and autonomic actions greatly influences our waking lives. Now we’re learning how to train our unconscious selves for the benefit of our daily actions.
They may look odd, but it’s all part of Google’s plan to solve a huge issue in machine learning: recognizing objects in images.
When Google asked its neural network to dream, the machine begin to generating some pretty wild images. They may look odd, but it’s all part of Google’s plan to solve a huge issue in machine learning: recognizing objects in images.
To be clear, Google’s software engineers didn’t ask a computer to dream, but they did ask its neural network to alter the images based on an original photo they fed into it, by applying layers. This was all part of their Deep Dream program.
The purpose was to make it better at finding patterns, which computers are none too good at. So, engineers started by “teaching” the neural network to recognize certain objects by giving it 1.2 million images, complete with object classifications the computer could understand.
These classifications allowed Google’s AI to learn to detect the different qualities of certain objects in an image, like a dog and a fork. But Google’s engineers wanted to go one step further, which is where Deep Dream comes in, which allowed the neural network to add those hallucinogenic qualities to images.
Dreams might be a whole lot sexier than we thought – but not because of their narrative content. Neurologist Patrick McNamara's theory links the biological changes in our brains during sleep to human's inherent desire to procreate.
Carl Jung battled his one-time friend and mentor, Sigmund Freud, on a number of topics, though perhaps none as perniciously as dreaming. An entire cottage industry of depth psychology and journaling workshops grew out of Jung’s theories of individuation—integrating the conscious and unconscious. To Jung, dreams—the primal material of the unconscious—unlocked humanity’s archetypal code, revealing more than they concealed, in direct contradiction to Freud’s ideas.
