A #stablethread on the posterior cingulate cortext (PCC) and all its juiciness. I'm trying to map out the evolving understanding of how meditation effects the brain and the PCC became relevant for anxiety as it is highly implicated. 
For more on the entire brain, the thread from which this one descends, please see this thread:
The posterior cingulate cortex lights up when we are stressed. Its associated with mind-wandering and self-referential thought processes, the thoughts in our heads.
Deactivation in this area predicted reductions in stress. Being an expert in the technique was not required for it

A #stablethread on how to dance. I realize with my other thread (attached), that I was trying to show why dance is important and share my learnings.
With this thread, I will try to actually show you how to dance starting real slow, for beginners.

Here is an introduction.
Remember to actually get up and practice along with these if you are in a spot where you can get down.

Here is the first lesson:
Bouncing up and down, then switching feet to experiment with weight shifts.
All dancing happens from the feet up although neurological phenomena travel down to the feet and color your movement and experience. These are called descending tracts in spine

A #stablethread on Ayahuasca with an attempt to blend the pharmacology, history and experience of it into one entertaining and educational thread.

In the same way that people find a drug of choice like Heroin or Religion or Sports, we each also have a different plant medicine that draws us into its machinations. For me that is Iboga, not ayahuasca. More on Iboga here:
That being said, I'm fascinated by ayahuasca and its rapid ascension to most known of the very intense transformative psychedelics and I want to try to piece together the pharmacology and signficance of it even though the US federal government makes that incredibly hard.
A #stablethread on the extracellular matrix (ECM).
The best analogy I have for helping to visualize this devilishly difficult piece of anatomy to visualize is to see it as the forest through which the cells of your body wander and attach to. This stuff is really bizarre.

Before moving on, if you want to understand the overarching category to which the ECM belongs, check out this thread on connective tissue, with links to other types of connective tissue:
There are two basic components to the ECM.
First is the structural and fibrous proteins that provide the scaffolding or the structure which makes up the ECM. These proteins are:
1. Collagen
2. Elastin

A #stablethread on Pilates. To see the thread on my learnings for movement in general please see the following link:
What I'm really enjoying about Pilates so far is it's distinct lack of "super-spirituality" and its entire focus on the human body and its interaction with various props. I've found that traditional Yoga is more about destroying this idea that we are just the body.
Paradoxically, pilates is more realistic about just training the body in order to live a happy and healthy life as opposed to modern yoga which celebrates the sensuality of the body and traps us into mere sensuality while pretending to be "super-spiritual", look at Instagram
A #stablethread on the muscles of respiration or the muscles you use to breathe! As you read this make sure to pay attention to your breath and try to identify where these muscles are and what they are doing experientially.
Before going into all the muscles, please feel free to peruse the following threads for both the anatomy of the body:
and a table of contents for the thread on the category we are studying right now.

Before going on I should explain the 3 types of muscle tissue:
1. Skeletal (movement muscles)
2. Smooth (digestive muscles)
3. Cardiac (heart)
With my specialization in movement and bodywork, I mostly am familiar with #1 but I'm sure I will get into the other two, as I learn.

One of the most interesting things I've learned about skeletal muscles recently is that there are further subdivisions of it which are really important for movement.
First, consider your posture as you read this. Do you feel which muscles are supporting your spine at the moment?

Connective tissue is the glue that holds our body together. This one is the hardest one to visualize because its main role is to connect other types of tissue together. Think of it like all the people who make things work in our modern society but you never hear about, the cogs.
One of the most well-known types of connective tissue is fascia, but there is so much more!
Here is a thread I already built on Fascia:

A new #stablethread on all types of tissues in the body. Like my thread on brain anatomy, this one will serve as a table of contents for more in depth threads on each of the various tissue types. We have four basic tissues (with lots of subclassifications). Here they are:

The basic unit of the brain and the entire nervous system is the neuron!
Think of a neuron as an on-off switch or a gland filled with electricity that sends signals all over the body quickly. Groups of neurons cluster together and fire and wire together to accomplish goals

There are a couple of different ways to categorize neurons, but I will talk about the one that is most important for movement:
1. Sensory neurons
2. Motor neurons
3. Interneurons

I might not be knowing what I'm getting into here, but the plot thickens. The insular cortex is further subdivided into two units:
1. larger anterior insula
2. smaller posterior insula
I will have to give it a minute to see if I want to go one layer deeper in the simulation

I've decided that each sub region of each lobe does not need a separate #stablethread and will now commence shit posting about various regions and their function. Please do your own research. I'm just building mind lego castles for pure enjoyment and fantasy speculation.
A #stablethread on the limbic lobe of the brain:

One of the most important parts of the limbic lobe or the limbic system is the hypothalamus which I go into in this thread about hormones and the endocrine system:
Here I learned a new part of the hypothalamus called the lateral hypothalamic corridor which apparently is responsible for the drive to satiate thirst in humans beings. Cognitive science shows us that most understanding and language is based on metaphor.
A #stablethread on the anatomy of the brain in a hierarchical fashion. I will start with all the more meta-regions of the brain and then descend from there. First the lobes of the brain of which there are 6! I will create separate stable threads for each.
Before preceding, I will show the most meta of meta threads, the one on anatomy from which this descends for your perusing pleasure:

A #stablethread on Fascia!
This stuff is what connects one part of your body to every other part of your body. It was mostly ignored by anatomists until recently. There are a lot of mythical components of fascia that are currently being hyped, but also some really cool insights!

Here is the main thread from which this thread has been birthed if you want to learn more about functional anatomy:
There is not much consensus at the moment as to exactly where fascia begins and where it ends, or even what it does!
Robert Schleip argues there are four main functions of fascia:
Communication, Supply, Movement, and Shaping.

A #stablethread on the spine and all its majesty. This beautiful piece of evolution is truly a masterpiece to contemplate given its so important that one of the major classifications of life revolves around its existence:
Vertabrates (with spine) versus invertabrates (no spine)

If you want to read the uber thread where this thread came from then follow the link below and choose your own adventure:
There are 24 movable joints in the spine. The spine is mainly there to protect your fragile nerves from damage, but it's also a huge part of how we can move in so many varied and intricate patterns. Evolution seems to build off of earlier advances and the spine is no exception.
A #stablethread on talking to strangers.
I've been working with @socialanimal_us for a few years on an off and on basis. Yesterday I sent him a message saying I was desperately in need of help. I want to break free of this in person self-censorship that I experience regularly.

Ruben and another counselor taught me that if you aren't joking around with the strangers that you happen to share physical time and space with, your perception of the world could be reorganized until that happens naturally. Particularly in this time of online violence
The spice of life is other people. They are infinitely complex which makes them so interesting. When we censor our natural urge to express ourselves it is truly a form of violence that we are doing to ourselves. There is nothing to fear from other people (unless its mob time).
A new #stablethread on what I have learned about the principles of movement from riding skateboards all around the world.
To see the big kahuna thread of movement from which these insights are derived check this one out.

Skateboarding primarily trains balance, particularly balance under high stress of falling down at high speeds. Its not like a bicycle where you feel more secure. Riding a penny board means balance must be impeccable. I didn't start when I was young, I actually started at age 27.
Today I learned that skateboarding is preparation for single legs squats and single-leg squats can help with balance and strength on the skateboard. The stabilization required to remain balanced while moving is high. Notice in this video that I'm doing a mini one-legged squat.
Going to start an anatomy #stablethread.
First this amazing graphic of the cranial nerve. Cranial nerves are interesting because they exit directly from the skull rather than through the spinal cord. One of the most interesting ones is the vagal nerve

Its interesting because its a cranial nerve but instead of staying around the head in descends all the way down to the internal organs and innervates them giving them juicy relaxing neurotransmitters which make us feel all fuzzy inside.
I was prompted by this tweet to dig into which cranial nerve is related to Bells Palsy and its the facial nerve. Ive had issues with this nerve as well because of a operation gone wrong on my Tendomanibular joint
I currently see that science might not survive its encounter with populism and don't want to contribute to this new normal so will be restarting this #stablethread and will give up the category of "neuroscience" in exchange for "learning"
In humans, vision is such an important part of our learning apparatus. I've always found it fascinating that the part of our brain that processes vision lies in the back of our brain, not directly near our eyes in the front.
What is the intersection between imagination and the nervous system?
I accidentally cut off the previous COVID resource #stablethread so will be continuing here. Here are the ones that were cut off:
Lockdowns do not work in countries that do not do it immediately and fully (like New Zealand). If you miss the window they do not work. They need to be abandoned as policy for suppressing a virus but now its political so they wont be:
Can we pretty please start acknowledging that the Swedish experiment is the winner and get on with our lives?
I know your scared but fear is a bad place to make decisions from.

I've long been on the trail of a theory of movement and why modern humans are so maladaptive to physical environments. It just came to me in words. In nature there are two things you never see:
Shoes and Chairs
Shoes and Chairs
It's not to say that these tools aren't very handy. If I were trudging through the artic I would want me some shoes.
But when was the last time you walked outside barefoot on a sunny day? How often do you see others doing that?

Shoes:
They block a certain type of receptor called a pacinian corpuscle. These receptors sense vibration in the surfaces you touch. If your feet only touch the inside of your shoes you are essentially starved from sensation. Better to walk barefoot 5 minutes a day to train.
