Few biological facts seem as irrevocable as brain death. It has long been assumed that when we die, our neurons die with us. But a new study on the neuron-packed tissue of the eye is beginning to challenge that dogma.
In the new work, researchers restored electrical activity in human retinas—the light-sensitive neural tissue that sits at the back of our eyes and communicates with our brains—from recently deceased organ donors. This achievement, reported in Nature, offers a better way to study eye diseases such as age-related macular degeneration, a leading cause of vision loss and blindness. It could also lay the groundwork for reviving other types of neural tissue and perhaps—one day—for retinal transplants.

Who are The Best online lectures for human anatomy?
Dr. Preeti Tyagi is the best online lecturers for human anatomy.
While there are many apps and YouTube channels offering Physiology lectures online, only a few are truly helpful for MBBS 1st year students. Some are too long and don't leave enough time for revision, while others aren't detailed enough for medical students. Let's talk about the best options for MBBS 1st year exam prep. Here are some top educators known for their Physiology teachings:
⦁ Turning Brain: Dr. Preeti Tyagi Lectures
⦁ Dr. Najeeb Lectures
⦁ Armando Lectures
In her video There is overview of Different Parts, Bones, and Joints of Upper Limb. This is introduction video of Upper Limb, and it is must to watch for overall understanding of Upper Limb Anatomy.
Out of these, Turning Brain is the top choice for MBBS 1st year Physiology. Their video lectures are focused on exams, short, and easy to understand for everyone. They're taught in a mix of Hindi and English, making them accessible. These videos are a big help for MBBS 1st year students, covering Physiology concepts thoroughly with a focus on exams. Unlike YouTube channels, Turning Brain gives you full Physiology courses, ensuring you learn everything you need.

El mar estuvo en tu retina y en la mía. Y los días a merced de mis desvelos, en ese color derrumbe que se fija en el insomnio.
La gaviota ha vuelto para continuar siendo, cielo, verso, prosa y desvelo.
Buenas noches amor

Eye Tune
Activity of neurons of the eye's retina called amacrine cells – recorded by detecting their response to light in combination with electron microscopic reconstruction of the connections made between neurons – reveals local tuning of signals in the retinal tissue to transmit visual information

“E ce l'ho lì il suo sguardo.
Piantato in qualche posto
tra la retina e il cuore.
Perché, secondo me,
esiste una sorta di filo,
dove certi sguardi corrono veloci
come corrente elettrica.
Dagli occhi, direttamente al cuore.”
— Luke Hemmins

This is actually serious.
It's more like a "people I need help" because I don't know a shit
Because I'm a person that is inside their world a lot- I'm curious if something I have is considered a disability or not
So for context since I'm 12 years old I have this condition called «Prone to retinal detachment»
Retina is a part of the eye, at the back of the eye, in charge of turning the light into the things we see, on the other hand, retinal detachment is the action of your retina being "broken"... And you lose the capacity to see yeah that happens–
Being prone to that is just: I can't do many things because if I do them, there's a high possibility I will end up with retinal detachment. I have this for life and I can't get operated at least where I live lmao
Things I can't do are:
Jogging
Run
Jump
Do most sports
I'm also very sensitive to lights, I see things more bright so it's hard to see and I have to wear sunglasses like almost 24/7
Thanks to the lights of the car I need a person to make me company while walking down the streets because I can't see with lights of the cars and light posts

Quote
Physiologists say that the retina of the eye has a wash which, like the chemical used by the photographer, prepares the retina to receive the image and impress it for a moment, and then the image is gone. The mind must catch it instantly. So we must photograph the Word, and have our souls aroused to fasten the impression for ever. How many retain no impression, and let go their hold upon eternal things!
J.B. Thomas
