Old mitochondria get digested by the cell (mitophagy) and new ones are born out of existing ones, the same way bacteria multiply.

Humans are the only species capable of generative invention: bird figurines, the product of the Systemizing Mechanism, that evolved in the modern human brain 70-100K years ago https://t.co/sheI8iyznk
Wonderful lecture by Daniel Kahneman. His System 1/System 2 distinction has a lot of relevance for understanding mental health conditions. System 1 makes automatic, rapid emotional associations, whilst System 2 involves effortful, slow checking. Phobias are just one example, where emotional self-regulation goes unchecked, leaving anxiety to spiral upwards at lightning speed
What is life? And what is consciousness? Do you think that Classical neuron firings and it's networks can give an integrative approach to the whole story?
I don't think so!

Your organs aren't just following orders from the brain.
A new Yale study finds that organs like the heart, lungs, and intestines build and shape their own nervous systems, then communicate back to the brain in a two-way conversation. One of the most striking findings is that heart tissue can reprogram neurons from the gut to start behaving like heart neurons.
Researchers say the discovery could eventually open new paths for treating conditions like Parkinson's disease and other organ-based illnesses. See what else researchers found: https://t.co/82WnnIPmra
"I also do lots of yoga in the morning, like body manoeuvres (...) It keeps you flexible, young, smart and open. So I’m open to fresh ideas every day."

"On land, Clay Marzo struggled. Eye contact was hard. Small talk was harder. People thought he was rude, distant, difficult. In the water, he was untouchable. By 15 he had landed the first two perfect 10s in national surfing history. Coaches could not explain how he read a wave before it formed. At 18, Clay was diagnosed as autistic. Suddenly it all made sense. The intense focus, the obsession with the ocean, the way his brain locked onto patterns no one else could see. The thing that made him “different” on land was the exact thing that made him a genius on water" https://t.co/mnQrliS8K9
25 years ago our group proposed and tested the prenatal sex steroid theory of autism. Today there is now a strong body of evidence in support of the idea. Simply put, elevated sex steroid hormones (like androgens [e.g. testosterone] and estrogens) interact with genetic predisposition to change fetal brain development and increase the likelihood of the child having more autistic traits, and/or an autism diagnosis. Delighted our new 'Perspective' paper on this has just been published, with wonderful collaborators worldwide. Alongside deeper understanding of the biology of autism we need way way better support services for autistic people and their families, so they can enjoy equal human rights
I've been saying this for a while.
Now JAMA Psychiatry said it louder.

The real story of depression isn't in the monoamines... It's in the mitochondria. 🧵
