Crisscross

This is a number crossword puzzle. Enter one numeral character into each square. The clue consists of mathematical operations (e. g. "D.6 x 3" means, that the number you are looking for is three times bigger than number D.6).

crisscross

Across:
A.1 = D.6 x 3
A.4 = A.7 x A.7
A.5 = (D.3 x 7) - 1
A.6 = A.1 + A.5
A.7 = D.3

Down:
D.1 = ?
D.2 = A.7 x 6
D.3 = D.6 + 6
D.4 = A.4 - 210
D.6 = (D.2 + 9) x 1/7

Scientists shed new light on how the brain detects motion



Scientists have discovered that the neural pathways involved in detecting motion differ depending on whether the moving object is alive or not

If you’ve managed to avoid getting hit by a bus today, you should thank your brain, which is designed to detect motion in order to help us safely navigate the world around us. This ability is so vital for our survival as a species that we’ve even developed the capacity to detect “implied motion,” such as movement that is suggested in still photographs. Yet while most of us take this for granted, scientists have long struggled to understand the neural pathways that control this essential function.
Publishing their findings in the journal NeuroImage, a team of researchers from Dartmouth College have now shed new light on how the brain interprets motion, indicating that the two pathways involved in this process may be more integrated than previously thought. Additionally, their results suggest that motion is processed differently depending on whether the moving object is animate or inanimate.

Hallucinations may actually be caused by folds in the brain






Imagine hearing a voice that screams, “You’re no good at this and you’re going to fail every exam” but not knowing where it came from. Or suddenly seeing a poisonous snake slithering towards you. Even if you’ve never had a hallucination – a sensory event that is experienced as real, despite having no material world cause – it’s easy to imagine how frightening they can be.
Despite advances in brain imaging technology, we still have a limited understanding of the biological processes behind hallucinations. But new research has discovered that a key region of the brain, the paracingulate sulcus, may underlie the experience. This delivers a glimmer of insight into why some people are more likely to hallucinate and provides a neural target for treatments that aim to tackle such terrifying experiences.
When someone has a hallucination, the basic problem is that they fail to distinguish between real events and those created by the imagination. As a result, hallucinations have been described as an impairment in “reality 
monitoring”.

Have you heard of this new optical illusion ?

sight confusing optical illusion






This optical illusion will blow your mind. I don’t want to alarm anyone, but there's an optical illusion going around that can make you see black and white as green and red for up to three months… yes, three months.
A video called ‘Things You Might Not Know’ was uploaded on Tom Scott’s YouTube channel and it’s going viral, because just wow.
Apparently if you stare at the picture long enough it can affect the way you see certain colours, such as seeing black and white as green and red.
No one actually understands how the trick works, but we recommended that you DO NOT do it longer than 15 minutes.
