✨Have a big day doing RNA extractions tomorrow! 😄 . RNA (ribonucleic acid) plays an important role in coding, and regulating the expression of genes 👖😅 . We can analyse which genes are being ramped up or dampened down 😲(so cool, right?!) . First we extract RNA from cells, then synthesise cDNA (complementary DNA) 😉 . We use the cDNA for a technique known as Polymerase Chain Reaction (PCR) - this is where we amplify DNA copies and determine the expression of our genes of interest 👌 (and no, gene analysis doesn't happen in 3 seconds like you see on CSI 😂) . . . @neurosciencewithness . #neurosciencewithness #neuroscience #neuroscientist #melbourne #brainstem #instascience #research #researchfellow #PCR #chemistry #gradstudent #postdoc #phdlife #scicomm #biology #cells #molecularbiology #scientist #doctor #phd #genes #phd #neurons #brain #histology #imaging #laboratory #geneexpression #immunohistochemistry #microscope

This is my brain 🙆‍♀️ I was lucky enough to get the opportunity to volunteer at the Centre for Advanced MRI at @universityofauckland when I did my PhD there. I was the subject in the MRI scanner while radiology students were learning about different types of images that can be collected using MRI 〰️ MRI stands for magnetic resonance imaging, it is a way of viewing the tissues in the body to examine the anatomy. It works using magnetic fields and the natural properties of atoms in our bodies which emit particular radio-frequencies that are detected by a receiver in the MRI machine. The advantages of MRI is that it doesn't expose the patient to radiation, and it is non-invasive. There are also multiple types of MRI scans which can tell us different things about the body. 〰️ In neuroscience, the most common type of scan (T1-weighted) produces a low signal from bone - see my bright white skull! - and a higher signal from brain tissue. We can also distinguish between the two types of brain tissues, great matter and white matter. Grey matter - the part that contains all the cell bodies of your neurons - shows up darker than white matter - the part that contains lots of axons (telephone wires between neurons). 〰️ Image 1: view from the side of my head (in the middle) Image 2: birds eye view of my head (the white bit in the middle is my brainstem!) Image 3: view from the back of my head (in the middle) 🙆‍♀️🤓 #neuroscience #neuroimaging #MRI #science #scientist #stem #womeninstem #brain #research #medicalresearch #neurons #anatomy #greymatter #whitematter
“We rise by lifting others.” One of the most beautiful moments a teacher can experience is watching her students become the teachers. Our #6thgrade K2 buddy program is blooming with excitement and learning!!💚 Last week our #steam buddies learned all about brain cells called #neurons and their many parts~ the 6th teachers led their buddies through inquiry and into building and presenting models of their neurons.

Schizophrenia is a brain disorder that can cause hallucinations, delusions, and other cognitive impairments. Researchers have found that a group of neurons in the ventral hippocampus may play a role in some of these symptoms. These neurons, called GABA neurons, are highlighted in red in the cross-section of a mouse brain above. When researchers prevented the neurons from communicating with other neurons in mice, they showed behaviors associated with schizophrenia in people. This finding not only shines a light on a potential cause of schizophrenia symptoms, but also offers insight on how GABA neurons influence behavior in general. Credit: Nguyen, et al.

L’uomo è un animale sociale, la cui vita dipende dalla capacità di capire cosa compiono gli altri, comprendendone le intenzioni e interpretandone i sentimenti: senza questa capacità gli esseri umani non riuscirebbero a interagire gli uni con gli altri, né tanto meno a creare forme di convivenza sociale.
Una grande scoperta neurofisiologica, avvenuta negli anni novanta, ha messo in luce l’esistenza di un meccanismo di comprensione: si tratta di un gruppo di neuroni visuo-motori che hanno la particolarità di attivarsi non soltanto quando si eseguono delle azioni, ma anche quando si osservano altri compiere quelle precise azioni (da qui il nome “neuroni specchio”). Si tratta quindi di neuroni per i quali “fare” e “veder fare” sono cose molto simili.
Dunque l’empatia, la comprensione degli altri, la capacità di predizione delle azioni di chi ci circonda e l'apprendimento per imitazione dipenderebbero da questo sistema mirror: sentiamo gli altri, perché siamo biologicamente portati a farlo e li imitiamo, perché, tendenzialmente, abbiamo un meccanismo innato, che ci porta a replicare certe azioni e ad inserirle nel nostro repertorio comportamentale.
Siamo quello che abbiamo, sentiamo quello che attiva i neuroni specchio e comprendiamo quello che riusciamo a vivere. “I neuroni specchio hanno plasmato la civiltà”. • #neurons #GiacomoRizzolatti #tedtalk #TED #neuronispecchio #doctor #neuroscience #psichiatria #science #science #nerd #brain #study #cervello #neuroni #scoperte #scienza #empatia

#Repost @brain_facts_org (@get_repost ) ・・・ The hippocampus, a brain region involved in learning and memory, is one of only a few areas in the brain that continues to create new neurons throughout adulthood. In this image of a mouse hippocampus (magenta), new cells are labelled in red, and mitochondria— the intracellular power packs responsible for driving cellular activities throughout the body — are labelled in green. To better understand the role mitochondria play in cell growth, researchers tracked the changes that took place in the mitochondria of new cells as they grew under normal conditions or after animals were exposed to exercise. They found that as fledgling cells in the hippocampus grow, the mitochondria undergo significant changes to support these cells. Specifically, exercise — which is already known to boost the creation of new neurons — increased the number and position of the mitochondria present in these cells, a key reminder of how behavior can affect ongoing brain development.

Retinal ganglion cells with axons converging at the optic nerve head: These are the cells that connect the retina to the lateral geniculate nucleus in the brain's thalamus. These are the cells that die and cause vision loss in conditions like glaucoma and optic neuropathies. In addition they are biologically fascinating and just simply beautiful from an aesthetic perspective. I started my ophthalmology career studying these cells in the laboratory and they still spark my curiosity. #ganglioncells #retina #neuroscience #brain #neurons #Repost @biologyoftheuniverse ・・・ This is not a stars cluster..

“Il miglior momento per rilassarsi è quando non abbiamo neanche un momento per farlo.” S.J. Harris. La domanda dunque è: esistono strategie efficaci per limitare l’impatto del distress? 1. RESPIRAZIONE DIAFRAMMATICA: Almeno 10 minuti al giorno in un ambiente tranquillo. Questa tecnica è molto utile in tutte le situazioni in cui sentiamo lo stomaco in subbuglio e il battito cardiaco in accelerazione, la corretta ossigenazione abbassa la pressione ripristinando l’equilibrio corporeo. 2. DORMI ABBASTANZA: Cerca di regolare i ritmi circadiani, creando una routine del sonno. 3. FA ESERCIZIO FISICO: Lo stress stanca la mente, ma non il corpo. Quando siamo molto carichi ci sentiamo appesantiti dal punto di vista mentale, ma il nostro fisico è in perenne attività. È necessario scaricare questa attivazione tramite sano esercizio fisico 4. CONTROLLA L’ALIMENTAZIONE: limita bevande come caffè, tè e tutte le sostanze attivanti, preferisci invece bevande come tisane rilassanti al tiglio, alla melissa, alla valeriana 5. PENSA POSITIVO: Impara ad affrontare i problemi quando si presentano, e non occupartene quando sono frutto delle tue fantasie 6. PROGRAMMA I TUOI IMPEGNI: Essere molto impegnati può essere fonte di stress, programmare le attività da fare può essere un valido aiuto senza dimenticarci di dedicare il tempo necessario a noi stessi. [Questi sono solo consigli, in caso la tua condizione lo richiedesse, contatta un esperto.] #stress #nostress #antistress #stresssymptoms #sintomi #psicologia #biologia #psychobiology #ormoni #hormon #neurons #connection #connections
5) I M A G I N G . . Fun step numero 👋⚄ is to take the slices we now stained with the colored antibodies, go to a massively expensive and powerful microscope and take pretty pictures! 😊 . . Our goal is it to compare different brains and count different types of neurons. By using this fancy microscope and doing some coding in fancy programs we can do automated counting as well as 3D reconstructions that allow us to fly through the tissue 🙆‍♀️ . . . How does it even work that we get these colors out and that we can perceive them with our eyes? 🤔👀 To understand that, we need to go through some basic physics. Bare with me! 😀 . . The colors our eyes are able to perceive 👀 (which is just a tiiiny piece of all the energy that is out there), are all found within the light 💡 you perceive as white in everyday life. So if you take that usual white light and split it up in all it's components, you would see all the different colors from red to blue ⚀⚂⚃⚄⚅! That is what happens when the sun rays ☀️ fall through rain drops💧, which split the white light up and build a beautiful rainbow 😍🏳️‍🌈. . . This is only possible, because every color has a different wavelength, a different energy! For example, red 🔴 on one side is veeeerrryyyy long and wide in it's repetitions 📈📈📈📈, and blue 🔵 on the other side is supershort and quick 📉. Infrared is even loonger and ultraviolet shorter, but we cannot see those waves with our eyes 👀 . . ➡️ Now back to the brains: the color tags that we put on them two steps ago, are flourescent 🚩. These flourophores, if hit by a intense light of a certain wavelenght (like a laser🔦), will absorb (swallow) a certain amount of energy 🎂, and emit (spit out) the rest of the light energy that is left over🍰, which will be a new, weaker wavelength of less energy. That is the one we will finally catch with special detectors and see on the screen. . . Each of the different antibodies has a different colored flourophor attached to it and will in this way produce the different colors and we can use these powerful data to analyze our samples.🙆‍♀️ . . Here in blue: Neuronal cell bodies. In red: Neurofilament, a part of the neuronal skelett. .😘

🌀 . Make it a good Monday and let gratitude re-wire your brain! It's a choice 💚 . "Neurons that fire together wire together. Mental states become neural traits. Day after day, your mind is building your brain. This is what scientists call experience-dependent neuroplasticity. . Every time you take in the good, you build a little bit of neural structure. Doing this a few times a day—for months and even years—will gradually change your brain, and how you feel and act, in far-reaching ways." . — Rick Hanson Ph.D. @rickhansonphd . . . . #thegratitudeattitude #gratitude #thegratitudeattitudejournal #attitudeofgratitude #gratitudeattitude #gratitudejournal #mentalhealth #grateful #appreciation #mindfulness #presentmoment #journaling #appreciation #neuralstructure #science #brain #positivity #rickhanson #neuroscience #thinkpositive #berlin #sky #neurons

I should probably be posting more cool things, but sometimes this stuff gets so repetitive that the 'coolness' sometimes dilutes itself. But anyway here's a picture of a mouse brain with schizophrenia. The green is a protein called Parvalbumin. It's a calcium binding protein that is super important for regulating action potentials and electrical currents through the brain. There is less of it in schizophrenic mice, hence less efficient communication between neurons. The cyan is dopamine transporter, which is responsible for transporting......dopamine out of synapses. In schizophrenia, there is a sex difference in the expression of dopamine. Female mice produce a lot less dopamine transporter, making them extremely susceptible to mood changes and erratic behavior. The idea is that, as dopamine surges, it is more difficult for females to attenuate the response because there is less of the transporter to remove it from the system. This effect is not seen in males. I took this super dope pic. It was taken on an inverted confocal microscope. The picture was about 1GB and took like 25 minutes to take. #sciencephotos #schizophrenia #scienceart #neurons
Another recent #SciArt series of mine is called "Thoughts," which explores the morphology of groups of #neurons overlaid via their cell bodies. This is "Thoughts 86," which includes 86 neurons in turn. All neurons were computer generated by a lab at MIT. Importantly, all 86 are visible (none are entirely obscured by overlay) but visually it's mostly impossible to tell which dendrite/axon belongs to which neuron. I like to emphasize the messy, intertwined, jungle-like quality of the #brain - while these pieces are not meant to represent actual neural architecture, and are more concerned with the inherent aesthetic of the neuronal form, this is my artistic answer to "What is the shape of thought?" This question is one I come back to repeatedly, inspired by and because of the profound influence William James and his "Principles of Psychology" had on me as a younger artist.
