The neuroscientists I spoke to said the big principles that underlie how our brains process what we see also underlie most of our thinking. Illusions are “the basis of superstition, the basis of magical thinking,” Martinez-Conde says. “It’s the basis for a lot of erroneous beliefs. We’re very uncomfortable with uncertainty. The ambiguity is going to be resolved one way or another, and sometimes in a way that does not match reality.” In this scenario, the advent of High-Performance Computing, coupled with a huge amount of experimental data, boosted the development of extended data-driven spiking neural network models 16, 17, 18, 19. Irrespective of the single cell model employed and the level of electrophysiological detail, the connectivity strategy remains a critical determinant in the construction of networks 20. It matters because scientists believe the same basic processes underlie many of our more complicated perceptions and thoughts. Neuroscience, then, can help explain stubborn polarization in our culture and politics, and why we’re so prone to motivated reasoning. If there is a spike, it will be hard to discern whether it was reopening or protests, so people will go with their prior,” Wallisch replied. “As the priors are different, there will be massive disagreement. ... What’s truly terrifying is that given this framework, no matter what happens, [people] will feel vindicated, reinforcing the strength of the prior and increasing polarization.” But illusions remind us it does not. This is why illusions aren’t just science — they’re provocative art. They force us to reinterpret our senses, and our sense of being in the world. They tell us about the true nature of how our brains work: The same neurological machinery that leads us to discover the truth can lead us to perceive illusions, and our brains don’t always tell us the difference.

The center of the brain is complex and each component of the brain fits seamlessly together. For instance, the corpus callosum arches over the Massa Intermedia and the choroid plexus. It is not vital you know the names of these components for the drawing, but it will help to have a labeled diagram of the brain with you throughout the process. In Hantman’s view, what we experience as consciousness is primarily the prediction, not the real-time feed. The actual sensory information, he explains, just serves as error correction. “If you were always using sensory information, errors would accumulate in ways that would lead to quite catastrophic effects on your motor control,” Hantman says. Our brains like to predict as much as possible, then use our senses to course-correct when the predictions go wrong. We don’t have the necessary machinery, and we wouldn’t even want it, to process carefully all of the amount of information that we’re constantly bombarded with,” says Susana Martinez-Conde, a neuroscientist and illusion researcher at SUNY Downstate Medical Center.With fMRI neuroimaging, which allows researchers to map brain activity, Cavanagh and his team could ask the question: If we perceive each animation similarly, what in our brains makes that happen? What’s the source of the illusion in the first animation? “We want to find where the conscious perception diverges from the physical sensation,” Cavanagh says. Trace a curved line from the outline to the middle of the line you just made. To make another segment of the brain, lightly draw a line from the original top of the brain. Make it curve slightly so it connects to the middle of the line you just drew. [9] X Research source

We can also give the brain drawing a light sketch, slightly detailing the different shapes and forms of the components. We are not trying to do a hyper-realistic rendition of a brain cross-section. However, we want some slight shading to help describe the form of the brain. As we constantly refer to our source image whilst shading, again, we want to be reminded of the pressure that we are applying to the pen as we shade in. Whilst focusing on the center of the brain, consider each component and how they are positioned next to each other. Since our source image is in color, we can also play around with the various degrees of contrast that we apply to our drawing with our pen.Don’t believe it? See for yourself. Here’s a simple illusion that reveals our visual system is a bit lagged. Most of the time, the story our brains generate matches the real, physical world — but not always. Our brains also unconsciously bend our perception of reality to meet our desires or expectations. And they fill in gaps using our past experiences. In terms of coping with stressful situations, experiments reveal that oxytocin (the feel good hormone) stimulated by the presence of someone who cares, reduces the activation of the brain’s fear pathways and explains why social support reduces stress.

Sometimes, especially when the information we’re receiving is unclear, we see what we want to see. In the past, researchers have found that even slight rewards can change the way people perceive objects. Take this classic image used in psychological studies. What do you see?

Lastly, we will be using a source image, which is linked in this tutorial for reference. Learning how to draw a brain requires having a diagram to guide us along the way as we learn about the different components that make up the brain. All items can be found online:
