Ever had one of those moments? You’re cruising along, maybe a little lost in thought, and then – BAM! – a sudden loud noise, or a near-miss on the sidewalk. #alertness #bloodpressure #fightorflight #neurotransmitter #Noradrenaline #Norepinephrine #stresshormone

Which neural circuits allow memory retrieval to influence behaviors? This study shows how #fear #memory activation initiates & sustains #FreezingBehavior in mice via the interplay of #norepinephrine & activation of different prefrontal #neuron subtypes @PLOSBiology https://plos.io/3TGqt7a

My GF by mistake came up with a word that I will be using: #Norepineuphoria
Or the feeling of anger that happens when you argue with people passionately. Which comes from the neurotransmitter #Norepinephrine
Heart PET Scans: A Breakthrough Predictor of Parkinson’s and Lewy Body Dementia Years Before Symptoms
By analyzing cardiac norepinephrine levels in individuals with Parkinson’s risk factors, the research led by Dr. Goldstein offers a potential method for early detection and intervention in these neurodegenerative diseases.

My new #ComplementarySubPodcast #podcast with Raceme on the topic of my last article where I discuss how #psychopathy #paternalism and #Norepinephrine ( Acute Stress Response ) are the 3 problems keeping us from True #Freedom.
Big 3 things that damp #Freedom around the world are:
When you feel 'in love', what you're actually feeling are the effects of dopamine and norepinephrine.

The most frequent “interventions” that were judged appropriate were:
1/ Doing nothing: #Zentensivism is not #WhatAboutism, it needs documentation and #Monitoring to ensure we have enough argument that it is the right thing to do
2/ Improving #brain #perfusion in situation at risk of #ischemia based on #TranscranialDoppler by either #osmotherapy and/or #norepinephrine

The #human #brain produces a #neurotransmitter #chemical that is the #drug of #censorship . It's called #norepinephrine . This is why even the most avid #freedom and #freespeech activists fall to censorship.

- locus #coeruleus in the brain, which controls much of #norepinephrine production, has a strong influence on lower-bowel function, almost half of panic-disorder patients have irritable-bowel symptoms as well.
🧫 The synaptic terminal has these entities here, which are called synaptic vesicles, and they're small, little organelles.
🧫 They're little vesicles made of a membrane; just like the cell has a cell membrane, these vesicles have a vesicular membrane.
The neurotransmitters are within the vesicular membrane.
🧫 And, the neurotransmitter can be any number of a number of different molecules — #Glutamate, #GABA, #Serotonin, #Dopamine, #Acetylcholine, #Glycine, #Norepinephrine, #Epinephrine, #Histamine, #ATP.
🧫 The neurotransmitters are packaged in vesicles. The second thing that's important about this is that we can use the synthesis of a #neurotransmitter as a therapeutic tool.
🧫 So, for instance, Dopamine is missing in #ParkinsonsDisease.
It's not that dopamine isn't made per say, that's there's a problem with making it — it's that the cells that make it die.
🧫 There's something called 'Mass Effect', which means that you take the starting chemical (the substrate) and then through a series of enzymatic processes reaction, through a series of enzymatic reactions, we end up with a neurotransmitter.
🧫 In the case of Dopamine, what we do to treat in most people with Parkinson's is that we give them the substrate — and so that (drug) is what is commonly known as #Sinemet or #Parcopa.
🧫 So we flood the system with substrate, and the goal is to get a little bit of that neurotransmitter out of the system.
