Your Mind on Trial

The British television series Black Mirror has, at times, been disturbingly prophetic. In season 2’s The Waldo Moment, a crude comedian runs for Parliament to disparage the system only to find himself a front-runner. In April 2019 Volodymyr Zelensky, a comedian who had previously played the role of Ukranian President on a popular TV show, […]

In a world of “blind imagination”: The science of Aphantasia

[En Español] Picture yourself in your childhood home. Imagine your bedroom – your bed, perhaps some posters on the wall, and whatever other salient features you can conjure with your mind’s eye.  Do you see yourself in it, or are you seeing it as though through your own eyes…or do you not “see” anything at […]

Through the Looking-Glass, and What the Brain Sees There

  She complained of recurrent attacks during which she feels that her body is growing larger and larger until it seems to occupy the whole room. “I feel,” she said, “that I have got so big that if I put out my hand I could touch the far wall.’ Less frequently, she feels that she […]

To See, but not to See

In 2008, a man shocked researchers when he successfully walked through a hallway cluttered with boxes, trash cans, and other junk without stumbling into anything. That may not seem terribly impressive (particularly if you’re used to navigating through a messy bedroom every night), but here’s the catch: that man was blind. That man, known as […]

We Are All Actually in the Matrix

I’m not kidding: you, me, and everyone else are actually in the matrix. But it’s not quite the same matrix as in the movie “The Matrix.” We are (probably) not being grown and harvested by robots who (somewhat inexplicably) have chosen to use us as a power source.

No, I’m talking about your brain. Your brain is your own personal matrix. It enables your consciousness, your sensations, your positive and negative feelings.

It lies to you. All the time.

Let me show you.

What can your tongue see?

Picture this: you’re riding your bike on a cool fall afternoon. You’re blind but have no difficulty navigating through the streets without the aid of your eyes. Rather, the world comes into view through waves of sound bouncing off nearby objects in response to the bursts of clicking noises you create with your tongue. Since […]

You Do Have a Sixth Sense – and More!

Ever wish you had more than just five senses? Sure, it’s cool to see, hear, touch, smell, and taste the world, but wouldn’t it be great to be able to sense other things? Perhaps you would prefer X-ray vision, telepathy, the ability to tell the future, or maybe you want to see dead people (or […]

Lucy’s Brain: Use it or lose it

With the Lucy movie coming out, we’ve been really curious here at NeuWrite about what marvelous new life skills Scarlett Johansson will accrue, now that she can use more than 10% of her brain. As forward-thinking neuroscientists, we’ve been speculating: what would Lucy be able to do with such incredible and unprecedented brain power? The […]

Wiring Eyes

We can probably all agree that eyes would just be useless bags of vitreous humor if not for their wiring to the brain.  It’s the highly precise connections between specialized cell types within the eye and their specific target cells within the brain that allow us to visually experience our world.  But how do these […]

Retinal Direction Selectivity… Reversed!!!

In a recent paper, “Visual Stimulation Reverses the Directional Preference of Direction-Selective Retinal Ganglion Cells” (2012), the lab of Dr. Marla Feller demonstrated direction reversal of a subgroup of  Direction Selective Ganglion Cells in the mouse retina.  The finding is contrary to the predominant dogma that direction selectivity is endowed by circuity that is hard-wired.  […]
