Deeper Than Ink | 01

P R E M I S E ⇒

Should you fall in love with someone, even in the slightest, your skin becomes marked with vibrant colors that depict the story of your emotions. A tattoo, per say. However, should they or you fall out of love, the bright hues dull to black and the feelings you once had for each other melt away. To many, it’s a blessing to not have to live with the pain of your past. But what’s the point when you have too many reminders–say 27?

Pebbles bounced against the sidewalk, caught between the concrete and the rubber soles of boots dragging across the pavement. The movement was slow and the sound was reminiscent of a modern romantic defeat, another tally to add to the chalkboard. Another inked reminder that would be incomplete on a pale skin canvas.

A single finger rose to itch at the back of a studded ear, scratching just above the intricate black swirls of patterned water that was splayed over a neck. The owner of this design–and the 27 others cluttering his skin–wasn’t a lost cause or a serial romantic as many had come to believe. But potentially the most unlucky man in the world.

There were many others like him, decorated in dozens of these brandishes to signify their accomplishments in a manner akin to a trophy shelf. Their skin was littered with these marks of past lovers who were only intended to become blackened symbols. However, hoarding tattoos of ones he adored was not a game to him like it was to others; he feared the attention and judgment that his ink gave him.

He was enamored by people and their stories, the things they had to say and the words that they would whisper to him. Falling for them was simply a side effect of his own curiosity that he had no control over, as the patterns would only appear when the emotions were mutual. People were drawn to him, not for the art etched into him, but for his elegant thoughts and charming words.

“So, what now?”  I shouldered aside the curtains and looked out on the strip baking in the mid-morning sun.  “You’re just gonna drop me at Clarke’s feet an’ that’s that?”

“For my part, yeah, that’s that.  I give you to Clarke, and I go back to France with Barat.”

I turned at the mention of Barat and gave Cas a rueful smile.  “Right.”  I took another drag of my cigarette and let the smoke curl out of my mouth as I exhaled.  “I gotta tell you, Cas, I’m disappointed by this turn of events, but you’re right.  I should have seen this coming.”

“Don’t be too hard on yourself, Kane,” Cas grinned.  “It’s not all bad.  I hear Cook treats Turner real nice.”

I felt my facade falter, and Cas saw the twitch in my jaw.  At my back, my fingers began to twist desperately, trying to find a way to slip my bonds and then snap his neck, just to keep him from talking.

“Do you actually think I’m going to believe anything you say at this point?” I asked.  My jaw clenched.  “Alex is a lot of things,” I said, “but he’s not the cheating type.  Not my Alex.  Not on me.”

“I knew you wouldn’t be swayed by words, so, here.  Valensi has been keeping a close eye on things down in LA.”  He fished into his pocket, pulled out his phone, and unlocked it.  “See for yourself.”

He set the device down on the table and I stood over it, glaring down at the screen.  The trembling in my veins turned to shaking, and I bit my tongue against the growl that threatened to tear out of my lungs at that moment.  There, in perfectly pixelated detail, was an image of Alex seated on the edge of the bed in the poolhouse, Cook’s quarters, and Cook curled up behind him, a guitar in Alex’s lap.

I suddenly remembered the room at Barat’s villa, the one filled with guitars, but I barely recognized the smile on Alex’s face.  He hadn’t looked at me like that in months.  My stomach turned sour.

“I’m sure I don’t have to tell you who bought that guitar for Cook, do I?” Cas’ hand hovered over the screen and he swiped to the next picture, this one zoomed in, the guitar on Alex’s lap clearly forgotten, and Jamie’s gaze trained on Alex’s face.

“Yeah, Cook sure likes the pretty ones.  Girls, boys, doesn’t really matter for him.”  Cas swiped again, and Jamie’s profile eclipsed Alex’s in what I knew was kiss.  Cas went on.  “As long as they need saving.  And he did, you know?  You did a number on that boy, Kane.  I’m not even that big of an asshole.”  Cas shook his head and heaved a dramatic sigh.  “I mean, it’s kinda been like watching a soap opera unfold around here.  You practically shoved that kid into Jamie’s arms.”  Once more he swiped, and the picture was clear as day: Alex on his back, and Jamie climbing all over him.  “Guess what he was doin’ while Helders was bleeding out on Fogarino’s carpet?” Cas mocked in a whisper.

Il tensore di diffusione (DTI) è uno strumento di risonanza magnetica attraverso il quale si possono costruire immagini biomediche anche tridimensionali, ma di tipo intrinseco.
Il tensore usa il calcolo infinitesimale per definire nozioni geometriche di distanza, angolo e volume e studiare le curve di strutture anatomiche nelle quali una dimensione è di molto maggiore delle altre due (per esempio i fasci di fibre nervose della sostanza bianca).
Consente di stimare, oltre la velocità di diffusione delle molecole di acqua, anche misure relatie alla quantità di anisotropia e alla direzione principale della diffusione.
Le misure che si ottengono con la DTI vengono utilizzate per studiare le proprietà della sostanza bianca e per indagare la connettività anatomica.

Musical Training Creates New Brain Connections in Children

Taking music lessons increases brain fiber connections in children and may be useful in treating autism and Attention Deficit Hyperactivity Disorder (ADHD), according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

(Image caption: Fibers belonging to the greater forceps pre-musical training are observed (A, B, C). Fibers belonging to the same patients after 9 months of musical training are observed below (a, b, c))

“It’s been known that musical instruction benefits children with these disorders,” said Pilar Dies-Suarez, M.D., chief radiologist at the Hospital Infantil de México Federico Gómez in Mexico City, “but this study has given us a better understanding of exactly how the brain changes and where these new fiber connections are occurring.”

The researchers studied 23 healthy children between the ages of five and six years old. All of the children were right handed and had no history of sensory, perception or neurological disorders. None of the children had been trained in any artistic discipline in the past.

The study participants underwent pre- and post-musical-training evaluation with diffusion tensor imaging (DTI) of the brain. DTI is an advanced MRI technique, which identifies microstructural changes in the brain’s white matter.

“Experiencing music at an early age can contribute to better brain development, optimizing the creation and establishment of neural networks, and stimulating the existing brain tracts,” Dr. Dies-Suarez said.

The brain’s white matter is composed of millions of nerve fibers called axons that act like communication cables connecting various regions of the brain. Diffusion tensor imaging produces a measurement, called fractional anisotropy (FA), of the movement of extracellular water molecules along axons. In healthy white matter, the direction of extracellular water molecules is fairly uniform and measures high in fractional anisotropy. When water movement is more random, FA values decrease, suggesting abnormalities.

Over the course of life, the maturation of brain tracts and connections between motor, auditory and other areas allow the development of numerous cognitive abilities, including musical skills. Previous studies have linked autism spectrum and ADHD with decreases in volume, fiber connections and FA in the minor and lower forceps, tracts located in the frontal cortex of the brain. This suggests that low connectivity in the frontal cortex, an area of the brain involved in complex cognitive processes, is a biomarker of these disorders.

After the children in the study completed nine months of musical instruction using Boomwhackers—percussion tubes cut to the exact length to create pitches in a diatonic scale, DTI results showed an increase in FA and axon fiber length in different areas of the brain, most notably in the minor forceps.

“When a child receives musical instruction, their brains are asked to complete certain tasks,” Dr. Dies-Suarez said. “These tasks involve hearing, motor, cognition, emotion and social skills, which seem to activate these different brain areas. These results may have occurred because of the need to create more connections between the two hemispheres of the brain.”

The researchers believe that the results of this study could aid in creating targeted strategies for intervention in treating disorders like autism and ADHD.

GAHHHHH. YUURI'S TIE! AND VIKTORS FACE IN THE FIRST PANNAL!! *DIES*

Oh, glad you like Yuri’s tie! :D
Ties are kinda interesting, and, I last minute decided a striped one looked good on him, good to know I was right ^^
And EHEHEHEHEHE
Victor’s face in the first panel might just be my favorite thing XD
SO GLAD THAT YOU LOVE IT TOO!!
POOR MAN, HE TRIED SO HARD

So there’s loads of different neuroimaging methods out there that are used depending on what it is you’re looking for! I’ve had the privilege of actually studying it and there’s so so many different types more than just functional MRI that people don’t really know about so here are a few and what they’re used for an how they work.

MRI - Magnetic Resonance Imaging

The most commonly used form of neuroimaging and for good reason. MRI uses the body’s tissue density and magnetic properties of water to visualise structures within the body. It has really incredible spatial and temporal quality and is predominantly used in neuroscience/neurology for looking for any structural abnormalities such as tumours, tissue degeneration etc. It’s fantastic a fantastic form of imaging and is used in numerous amounts of research.

Functional MRI (fMRI)

These images are captured the same way as MRI but the quality is a little bit lower because the aim is to capture function (those blobs you can see) as quickly and accurately as possible so the quality is compromised a little bit. Nonetheless, fMRI usually uses the BOLD response to measure function. It measures the amount of activity in different areas of the brain when doing certain things, so during a memory test for example, and it does that by measuring the amount oxygen that a certain area requires. The increased oxygen is believed to be sent to an area where there is more neuronal activity, so it’s not a direct measurement but rather we’re looking at a byproduct. There are numerous studies trying to find the direct link between the haemodynamic response and neuronal activity, particularly at TUoS (where I’m doing my masters!) but for the moment this is all we have. This sort of imaging is used a lot for research and checking the general function of the brain, so if you were to have had surgery on your brain, they may run one of these just to see which areas might be affected from it and how, or in research we’ve used this a lot to research cognition - which areas are affected during certain cognitive tasks (ie my MSc thesis - Cognition in schizophrenia and consanguinity). 

Diffusion Tensor Imaging (DTI)

This is my current favourite type of NI right now! DTI is beautiful, unique and revolutionary in this day and age, it’s almost like sci-fi stuff! DTI measures the rate of water diffusion along white matter tracts and with that calculates the directions and structural integrity of them to create these gorgeous white matter brain maps. They are FANTASTIC for finding structural damage in white matter - something that is making breakthroughs in research lately ie. schizophrenia, genetics and epilepsy. It measures the rate of diffusion which tells you about possible myelin/axonal damage and anisotropy, so the directions and if they are “tightly wound” or loosely put together - think of it like rope, good FA is a good strong rope, poor FA is when it starts to fray and go off in different directions - like your white matter tracts. My current research used DTI and it was honestly surreal to work with, the images are also acquired through an MRI scanner so you can actually get these images the same time you’re getting MRI’s done, functional or otherwise! 

Positron Emission Tomography (PET)

One of the “controversies” (if you could call it that) is the use of radioactive substances in PET scanning. It requires the injection of a nuclear medicine to have the metabolic processes in your brain light up like Christmas! It uses a similar functional hypothesis to BOLD fMRI, in that it is based on the assumption that higher functional areas would have higher radioactivity and that’s why it lights up in a certain way. It depends on glucose or oxygen metabolism, so high amounts of glucose/oxygen metabolism would show up red and less active areas would show up blue, perfect for showing any functional abnormalities in the overall brain. However it has incredibly poor temporal resolution and due to it’s invasive nature, MRI is chosen more often. (The pictures are gorgeous though!) 

Electroencephalography/Magnetoencephalography (EEG & MEG)

These are not “imaging” types in the stereotypical sense. They create a series of waves that you can physically see (think of the lines you get on a lie detector!). Electrodes/Tiny magnets are placed on the scalp/head in specific areas corresponding to certain brain structures. EEG picks up on electrical activity which is the basis of neuronal function, whereas MEG picks up on magnetic fields - the same property that is utilised by MRI. One of the biggest issues with EEG is that deeper structures passing through tissues get distorted, whereas MEG doesn’t because it only measures the magnetic properties. I’ve not had a lot of experience with either of these but I do know EEG is used in a lot of medical procedures to measure brain activity, from measuring seizures and sleep disorders to measuring brain activity in a coma. It’s fantastic and if you can actually figure out how to conduct and interpret results it’s an invaluable tool into looking at electrical activity.
