🛕 #JakhooTemple is an ancient temple in #Shimla, dedicated to the Hindu deity Hanuman.[1] It is situated on #JakhooHill, Shimla's highest peak, 2.5 km (1.6 mi) east of the Ridge at a height of 2,455 m (8,054 ft) above sea level.[2] Each year, a festival is held on Dussehra, before 1972 the festival was used to held at Annadale.[3]

According to the #Ramayana, #Hanuman stopped at the location to rest while searching for the #SanjivniBooti to revive #Lakshmana.

🧠 The emotion is executed by the autonomic nervous system in large part — not exclusively but in large part. And that in turn, the body-experience influences our emotions.

🧠 Under normal circumstances memories are made primarily about emotional events.
So, emotion is a great facilitator of memory formation.

🧠 So, every time we remember something, we actually make that memory again. We make the initial memory and then we reconsolidate that memory.

🧠 So, using just that information you can now understand why now some health professionals are treating post traumatic stress disorder by exposing individuals with #PTSD to a trigger in the presence of a beta blocker.

🧠 The beta blocker is preventing the sympathetic arousal, preventing the heart rate increase, and preventing the blood pressure increase.

🧠 So now, you've triggered a memory. But the person can't get all worked up about it — their body is unresponsive. We pharmacologically prevented that arousal.
And consequently now, when they remember it, they reconsolidate it without all that body memory.

🔴 SPINAL CORD INJURY

🔸 While the sympathetic nervous system is entirely contained within the thoracic cord (all the preganglionic neurons are in the thoracic cord), the parasympathetic preganglionics are split between the brain stem and the sacral cord.

🔸 And this has one very important consequence — for virtually any spinal cord injury, it doesn't matter where, any lesion that is anywhere near complete is going to isolate the sacral cord.

🔸 Now, the sacral cord does not make decisions. The spinal cord does not make decisions. It depends on input from the brain.

🔸 So, for example when an individual wants to wants to void urine, there is a whole part of front, pre-frontal cortex which decides micturation to occur.

🔸 The sacral cord is responsible for executing micturation, but it's not responsible for making the decision.

🔸 So, if we have a lesion somewhere in the chord that's rostral (towards the brain) from sacral cord, the sacral cord no longer has instructions from the brain.

🔸 Under normal circumstances micturition depends on two things:
1️⃣ The bladder, which is a smooth muscle, is contracted And it's contracted by neurons in the sacral cord, which is a parasympathetic effect. Parasympathetic neuron contacts a ganglionic neuron in the wall of the bladder, and that ends up contracting the the bladder wall.
2️⃣ In addition there's an external urethral sphincter that has to relax in order to let the urine out. And that is a voluntary muscle that your brain controls.

🔸 Now, in the case of a spinal cord injury, the sacral cord is on its own. So, as the bladder fills up, it starts to contract. It will contract. But this will never relax.

🔸 And so, what you have is the bladder contracting against a fixed, tight, closed sphincter. This is called "bladder dyssynergia". And it is a huge problem in spinal cord injury.

🔸 If somebody suffers from a spinal cord injury, a physician is going to make sure, is going to test, whether, the person is able to void urine or not. And if they're not, they're going to need medical intervention immediately.

👁️ Up in the most rostral part of the thoracic column that provides pregangloinics to the sympathetics, our preganglionics go to the eye. They go to the pupil they go to a few other places, but they also go to this eyelid.

👁️ The eyelid has two different muscles in it.
It has a muscle which is called "levator palpebrae", which is innervated, is a skeletal muscle and is voluntarily controlled; so, it has a voluntary muscle.
And it has a muscle in the back which is called the "superior tarsus", and the superior tarsus is a smooth muscle.

👁️ So, the superior tarsus is innervated by the sympathetics. And so, when you're asleep, having very low sympathetic tone — your eye closes.

👁️ When you wake up, sympathetic tone automatically comes up to some minimum, including a contraction of the superior tarsus, and up comes your eyelid.
