Hit me with a cool fact of the brain!(short if possible?I have duslexia)Thanks!✨

Ok from where you’re sitting right now I want you to try and slowly scan the room from left to right in one smooth motion. It’s not possible- instead, your eyes move along in little jumps called saccades. Now I want you to lift your pointer finger up and move it along from left to right, following it with your eyes. You’ll now notice your eyes no longer move in saccades but follow your finger in a swift motion known as a “smooth pursuit”. This movement allows our eyes to closely follow a moving object and evolved to aid us in catching prey or keep away from predators. Autistic people, abuse victims and those under the influence of alcohol or drugs often show a lack or defecit of smooth pursuit.

BIG UPDATE!

I’ve finally finished my biological patches set! After many months of designing, editing, and trial and error, I’m proud to post up photos of the final products!

They are woven with bright, beautiful colors that will endure many washes and adventures to come. They’re only $8 in my store:

Here are the first five patches in my biological patch set. Once all ten are made, the rainbow of studies will be complete! Each one is illustrated, digitized, and embroidered by me. Stay tuned for more! Next up is herpetology ;)

🌲Hooray!🌲 • The first piece from our Modern Wolf chronicle is ‘in the air'🖤🖤 • check out the Czech page👉🏻👉🏻https://m.facebook.com/prichazejivlci/

What is Brightness?

There has always been this nudge,right. The nudge to know what IS  brightness. The subtle divergence between what we perceive as dim and bright. What it really means!

The brilliance of the sun whose light emerges afar blinds us but yet the quotidian florescent light seems to oblivious to us. Why this madness ! It doesn’t make sense to me.

Light as a particle

Two light bulbs 100W and 20W respectively. It is obvious that the 100 W glows brighter than its counterpart. 

This is so because each photon ( a particle ) carries with it an amount of energy proportional to its frequency; E=hν. The energy dissipated per unit area is the energy per photon times the photons per unit area per second.

The 100 W bulb emits more photons per second than the 20 W bulb.

In this model, the photoreceptors in your eye undergo chemical reactions as a result of absorbing photons. The more photons absorbed per second, the brighter the light appears.

Light as a wave

In the picture of light as an electromagnetic wave, the energy carried by the light is proportional to the square of the wave’s amplitude.

In this model, the photo-receptors in your eye are oscillators. What is oscillating? Electric charge.

Charges are accelerated in response to the electric field of the light: the greater the electric field (or amplitude), the greater the amplitude of the oscillation, and the greater the electric currents in your eye (and the greater the brightness).

The human eye is truly a marvel. The level of serenity it brings to life is just enthralling.Have a great day!

This GIF shows how the toucan releases heat using its beak to cool itself off.

The toucan beak isn’t just beautiful, it’s also an adjustable thermal radiator that the bird uses to warm and cool itself. When the bird is hot, the blood vessels in their beak open up to allow more circulation to enable heat to escape. Birds can’t sweat so evolution has come up with some life hacks to get the job done.

When the eyes move, the eardrums move, too

Gruters found that when the eyes moved, both eardrums moved in sync with one another, one side bulging inward at the same time the other side bulged outward. They continued to vibrate back and forth together until shortly after the eyes stopped moving. Eye movements in opposite directions produced opposite patterns of vibrations.

Simply moving the eyes triggers the eardrums to move too, says a new study by Duke University neuroscientists.

The researchers found that keeping the head still but shifting the eyes to one side or the other sparks vibrations in the eardrums, even in the absence of any sounds.

Surprisingly, these eardrum vibrations start slightly before the eyes move, indicating that motion in the ears and the eyes are controlled by the same motor commands deep within the brain.

I just found your blog, and I'm in love! I'm about to graduate with my BS in neurobiology. Do you know of any quotes relevant to my major that I could put on my graduation cap? Thanks! ♥️

I may have gotten to this too late. Sorry about that! But here are some good quotes anyway. And congrats on graduating!

From physicist Michio Kaku:

The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe

From neuroscientist David Eagleman: 

What a perplexing masterpiece the brain is, and how lucky we are to be in a generation that has the technology and the will to turn our attention to it. It is the most wondrous thing we have found in the universe, and it is us.

From neurologist Oliver Sacks:

Every act of perception, is to some degree an act of creation, and every act of memory is to some degree an act of imagination.

From neuroscientist Daniel Bor (I think it’d be cool if you fit this whole thing on your graduation cap):

There is nothing more important to us than our own awareness. We see the breathtaking beauty of snowcapped mountains, the exhilarating grace and speed of a cheetah on a hunt. We hear melodic birdsong in our gardens. We fall in love, or experience the joy of our child’s first smile. We compose and appreciate music, art, and literature. We talk and laugh with our friends and family. All these, and everything else we care about, are conscious events. If none of these events were conscious, if we weren’t conscious to experience any of them, we’d hardly consider ourselves alive—at least not in any way that matters.

When I’m reveling in a glowing pleasure, or even if I’m enduring a sharp sadness, I always sense that behind everything there is the privilege and passion of experience. Our consciousness is the essence of who we perceive ourselves to be. It is the citadel for our senses, the melting pot of thoughts, the welcoming home for every emotion that pricks or placates us. For us, consciousness simply is the currency of life.

From philosopher/neuroscientist/whiner Sam Harris:

You are not controlling the storm, and you are not lost in it. You ARE the storm.

From rhymer Dr. Seuss:

With your head full of brains and your shoes full of feet, you’re too smart to go down any not-so-good street.

From the zombie neurobiologist:

BRAAAIIINNNSSSS are both interesting and delicious
