Isaac Asimov in 1970

“I'm an adult, this is how I spend my money” moment.

Makes you wonder, why BBC is speaking with a TV psychiatrist and motivational speaker (this is how 'Dr. T' defines himself), and not with the scientists actually investigating what Brain fog is? #NeuroCovid #LongCovid

How did assaults on science become the norm — and what can we do? Great review for @peterhotezmdphd.bsky.social and @michaelemann.bsky.social's new book. I already ordered mine. #ScienceUnderSiege

AI investment is booming, but what about understanding human intelligence? 15% of the NIH grants cancelled this year are in #Neuroscience. Over $323 million lost. The image below is from a 94 Y.O donor, part of a project to understand the 'superager brain' that lost its funding. 💔 #MicroscopyMonday

just like we learned in school

Brazil’s supreme court finds Bolsonaro guilty of plotting military coup

For students: how can we quantify neurodegeneration using #microscopy? One way is to use a marker like 🟡 below (SMI32). It identifies a population of pyramidal neurons that is lost early in neurodegenerative diseases like Alzheimer and Parkinson. And after some viral infections 👀👀 #Neuroscience

Microglia Megazord activated! Check these brain immune cells🔵 responding to #SARSCoV2 infection. Compare to the image on the right from a control. Neurons: 🟠NeuN, Microglia: 🔵Iba Do you know what caused this? COVID-19 Do you know what did not cause this? Vaccines. #FluorescenceFriday #NeuroCovid

The Future of AI Lies in Monkeys, Not Microchips. Neuroscience research on primates will help us learn how to build an efficient thinking machine. www.wsj.com/opinion/the-...

That's my mentor, the person responsible for my love for microscopy. I spent my PhD in Brazil avoiding microscopes, afraid of breaking them (too expensive)! When I moved to the U.S for my Postdoc, I was fortunate to be encouraged to overcome my fear and discover my true passion ❤️🔬. @sfn.org

Are you planning to attend @sfn.org meeting this year? If yes, you will see this and other images of mine displayed at the San Diego Convention Center 🤓! I love seeing a blood vessel connected to the brain tissue! Markers used: astrocytes🟡, microglia🟣, neurons🟢, nuclei🔵 Happy #FluorescenceFriday!

What can you do to improve your microscopy images? I often receive questions regarding how to take better images, so let’s start with the basics: improve your sample preparation! No microscope can make a miracle if your samples don’t look great! Things I don’t do anymore: (1/5)

This is a direct immunostaining using the frontal lobe of a patient with Alzheimer. Why is there so little high-resolution microscopy being performed in human tissue? Question for pathologists. We can extract a lot of data, and in 3D! (Dream Theater sounds appropriate this time) #FluorescenceFriday

Not all heroes wear capes. Incredible work from @putrinolab.bsky.social. They have created a *FREE* manual for clinicians treating chronic illnesses associated with infections. #LongCovid #MECFS #LymeDisease and many others.

Exactly 10 years ago, I gave my first interview, and for @iflscience.com 😁! At that time, I was doing my master's thesis in Biophysics, and we discovered that the lack of prion protein disrupts dopamine and serotonin signalling in the brain and can cause depressive-like behavior. Time flies!

I have the best labmates; they come to work wearing my microscopy image! 😁 We are pro-mask, anti-brain damage, and airborne educated! If you like it, you can get the same t-shirt here: www.bonfire.com/pandemic-isnt-over/ Proceeds go to longcovidfamilies.org #LongCovid #covidisnotover

Looking at some human brains with neurodegeneration and investigating Tau accumulation (🟡) inside neurons (🟣) using super-resolution microscopy (also 🟢nuclei). All the flying 🟡pieces are from dead neurons, and the 2 below are also condemned to die. We still don't know how to avoid this😞

Yesterday marked 11 years since we lost #RobinWilliams to suicide. A reminder that the brightest smiles can sometimes hide the deepest struggles. He was misdiagnosed with Parkinson's when he had Lewy body dementia (confirmed on autopsy). Check your friends 🖤 #MentalHealthMatters

SC senator resigns after starting treatment for #LongCovid and then receiving an Alzheimer's diagnosis. "Doctors INSTEAD determined that Nutt had neurodegenerative disorder". Instead? Early-onset Alzheimer's (before 65 Years old) used to be rare, but it will not be anymore.

Post-acute viral infections are not new (note that I use 'post-acute,' not 'postviral' as viral persistence can occur long-term). Yet, society and the medical community continue to dismiss millions worldwide suffering from #LongCovid and other similar conditions.This is an excellent historical text:

Microglia to the Rescue | ‪Science #Microglia #Neuroscience

Let’s fucking name ‘em: Robert Kennedy Jr. Jay Bhattacharya Martin Kulldorff Marty Makary Robert Malone Tracy Beth Høeg Vinay Prasad Peter McCullough Mary Holland Paul Marik Pierre Kory Jeffrey Tucker Kevin Bardosh Retsef Levi And many others.

Tonight, please spare a thought to all our scientists and public health workers who have dedicated their careers to saving millions of lives. Despite their amazing work they are constantly threatened due to politicization and the unfettered spread of misinformation. It should not be like this 💔

Derrick Kardos died of complications of #LongCovid on July 18th. Let his words sink in.

Check this neuron infected with #SARSCoV2 being attacked by a microglia. Is this process beneficial or detrimental? Do we want therapies to inhibit microglia activation/neuroinflammation, but what if it means more neurons infecting other neurons? Neurovirology is fascinating! #FluorescenceFriday

Important paper by members of the European Academy of Neurology. "Healthcare systems should be aware of, and be prepared for a potential increase in the incidence of neurodegenerative diseases in the upcoming years." What has been the state of surveillance and awareness so far? #NeuroCovid

We might not be as hyped as San Francisco or Los Angeles, but we are the capital and we had the Governator.

But neurons are the most important cell type in the brain, right?

Happy #3DThursday! I'm quantifying some microglia morphology and pruning, trying to figure out why sometimes these cells start eliminating neuronal synapses 🧐 Markers: IBA1 for Microglia and PSD95 for synaptic protein. Z-stack image acquired with @zeiss-microscopy.bsky.social analysis with Imaris.

mRNA vaccines have been proven safe by the scientific and medical communities. Before use, they undergo extensive testing involving thousands of participants, monitored by regulatory agencies. Once again, the anti-science movement impacts all of us. What will we do if there is a #BirdFlu pandemic?

It ain't going away, no it ain't going away....

Karma is a bitch.

"Brazil’s Supreme Court orders house arrest for ex-President Jair Bolsonaro" What a beautiful day! One mass murderer down, who is next?

Analyzing how neurons🔵 and microglia🟡 (brain immune cells) interact and I vote for 3D microscopy videos with appropriate soundtracks 🤘 👩‍🎤🔬 #FluorescenceFriday

"Analyses of cancer survivors databases reveal that SARS-CoV-2 infection substantially increases the risk of cancer-related mortality and lung metastasis compared with uninfected cancer survivors." Mice data show #COVID drives the proliferation of previously dormant cancer cells.

Beyond brain fog: #COVID19 can leave lasting effects on the brain. Honored to be invited to write this editorial for the Journal of the Japanese Society of Psychiatry and Neurology. It relates to @virusesimmunity.bsky.social team's review.You can read it here: onlinelibrary.wiley.com/doi/10.1111/...

While in LA, went to check my favorite stars 🌟

Once we thought it would be nearly impossible to modulate #LongCovid in rodent models, but science is getting there. More evidence for direct #COVID neuroinvasion, viral persistence in the brain , and more explanations for cognitive and psychiatric alterations... #NeuroCovid

Neurons on fire 🔥 ? Check how these microglia 🟡 interact with neurons 🔵 accumulating phospho-Tau 🔴, one of the hallmarks in #Alzheimer's disease. What is happening there? Are these microglia making things better or worse? #FluorescenceFriday #Neuroinflammation

Re-reading this book while waiting for my photos to finish, and thinking it should be a mandatory reading for all scientists, especially students and trainees. #STEMeducation

What happens when you compare brain scans from people before and after the pandemic started? A new study released today with 996 participants shows the pandemic accelerated brain aging for all, but those infected with COVID also presented reduced cognitive performance. #NeuroCovid #LongCovid

brazil is crazy good this week

Just pretty or useful? SMI32 🟡 targets a set of neurons more vulnerable to dementias. NeuN 🔵 identifies most mature neurons in the cortex. Quantifying neurons identified by both markers can give you insights into neurodegenerative processes occurring in the brain #Neuroscience #FluorescenceFriday

Check out this cool astrocyte multitasking in the brain! It manages a blood vessel on one side while supporting a neuron on the other. Everything in the brain, from blood vessels to neurons, is interconnected! 🔬 🧠 #microscopy #Neuroscience

Let's be nosy and noisy bitches 🤘🔬

Bird flu? Don’t worry, we fired the scientists. geneticliteracyproject.org/2025/07/15/b... via @geneticliteracy.bsky.social #H5N1 #Birdflu

Armond has #LongCovid. This is his experience. #CountLongCovid

This is what I am talking about 😁
