I'm a 3rd year psychology student and in the past two years I'd run away if I saw the word "neurotransmitter"... This video just made it so crystal clear. Thank you for this!
NOTES: 3 RULES of Neurotransmission: 1. What goes up, must come down: Intoxication and Withdrawal 2. A neurotransmitter is not easily fooled: Up regulation (decrease amt. of neurotransmitter, synapse will make itself more sensitive) and Down regulation (increase the amount of neurotransmitter, synapse removes receptors, making it less sensitive to the drug), observed during drug tolerance and withdrawal, regulation of G protein and DNA 3. With great power comes great responsibility: More efficacy and More Severe side effects • full agonist mimics the effect of a neurotransmitter • a partial agonist mimics it but only to a certain lower point • an antagonist blocks the effect of a neurotransmitter • inverse agonist produces an opposite effect to the neurotransmitter Dopamine: Reward pathway located in VENTRAL TEGMENTAL AREA, Nucleus Accumbens is imp area - D: Drive (governs motivation and reward) - O: Psychosis (blockade mitigates some features like delusions and hallucinations) - P: Parkinsonism (decreased secretion linked to Parkinson's pathology) - A: Attention (boosting dopamine improves attention and concentration) - M: Motor (strongly linked to motor function, imbalances cause conditions like Parkinson's) - I: Inhibition of prolactin (crucial in regulating prolactin release) (prior name: Prolactin inhibiting factor) When dopamine is blocked, one side effect is milk release from the breasts. - N: Narcotics (release of dopamine plays a role in addiction) - E: Extrapyramidal (controls motor functions, blocking leads to significant motor side-effects) Serotonin: complex molecule with many roles, comes from the RAPHE NUCLEI Also known as 5-HT (5-hydroxytryptamine) - Head: Depression, anxiety, social interaction (sociality), impulsivity, sex drive, migraines, satisfaction - Red: Platelet binding and adhesion, interfering with its function cause bleeding - Fed: GI tract motility (90% of all serotonin in GI tract), nausea (serotonin blocking medications effective) Serotonin Syndrome: 2 serotonergic drugs are taken at the same time Head: Headache, Agitation, Confusion Red: Flushed, warm skin (Hyperthermia, Hypertonia, Sweating, Tachycardia) Dead: Mortality 2 to 12% Norepinephrine: LOCUS COERULEUS origin, regulates Sympathetic nervous system - Fight-or-flight response - when active, Norepinephrine lots into the brain and epinephrine peripherally into the bloodstream - Sympathetic Innervation Central (Concentration, attention, vigilance, energy) Peripheral (Tachycardia, Hypertension, Glucose, Essential organs) Brain off and on switches: Gaba (off), Glutamate (on) GABA (Gamma-Aminobutyric Acid): - Inhibitory neurotransmitter - "Gaba" association with a boring lecturer inducing sleepiness - Relaxation (breathing and muscles), euphoria, no anxiety - Drugs that enhance GABA are often used to break a seizure. Glutamate: - Excitatory neurotransmitter - Association with mating for recall Histamine: The upper brain cortex depends upon a constant stream of histamine for activation, once supply is cut off, cortex shuts down - H for hay fever - I for itching - S for sleeping Antihistamine: Itching and hay fever disappears, patient gets sleep First generation anti-histamines: (diphenhydramine or benadryl) used for sedation as they work in both central and peripheral NS Newer antihistamines: (loratadine or claritin) works peripherally therefore advertised as non-drowsy Acetylcholine (ACh): opp of Norepinephrine, responsible for regulating Parasympathetic system - A: Autonomic functions (rest and digest functions: Bradycardia, GI motility, Salivation, Lacrimation, Urination and Sexual Arousal) - C: Contraction (neuromuscular junction) drugs that affect ACH peripherally are used against neuromuscular diseases like myasthenia gravis - H: Hippocampus (memory, learning, awakeness and attention), helps combat Alzheimer’s dementia, geriatric psychiatry Opioids: - Armed Chinese man association with the Opium Wars
• A: Analgesia (pain relief) • R: Respiratory depression (opioids make the respiratory center in the brain insensitive carbon dioxide so death and opioid overdoses via Ondine's curse) • M: Meiosis/ Constriction of pupils (pinpoint pupils) • E: Euphoria • D: Drowsiness • C: Constipation
I passed board today. I only used these RUclips videos and the purple book and I believe these are all you need. There is another channel on RUclips the one with the light 💡that I used. I didn't buy any questions or review. Purple book I got from a friend. Thank you so much for these videos they really helped me pass. Good luck.
@@only1mesabby the purple book is the ANCC guide to passing boards for PMHNP. The purple book and this book, along with the Fitzgerald course provided by my school is all I am using. Just those three items alone are enough to keep me busy.
THIS IS THE BEST MEDICAL INFORMATION CHANNEL EVER!! Me? Doubled Mastered in the health sciences from noted schools back East, worked in Medical Affairs Depts. with HUGE household name BioPharma. Oh, the stories I could tell from sitting @ board meetings. But can't tell... too many NDAs sighned!!
thank u..I'm a psyhchiatry resident and have been suffering with pharmacology all my life,,your videos helped me a lot and I passed pharma exams in my master's...really thank u so much
Important historical point: the Opium Wars were not fought because people wanted more access to opium, as you suggest. The Chinese tried to ban British opium sales in China to protect their citizens from addiction. The British, not wanting to lose their massive profits, started a war and forced the Chinese government to set up protected trade ports allowing them to continue shipping opium into China. Otherwise, great mnemonics and info, thank you!
EXCELLENT! EXCELLENT! EXCELLENT!👏👏👏 I have benefited so much from this. You've made this so much simpler and easily retained. I should be paying you tuition instead of my college🤦🏽♀️. Thank you very much😊!
I am an avid #MentalHealthAwareness advocate and performer, and I love this so much. I travel the country trying to bring that awareness on stages, in classrooms, hospitals, and on my RUclips channel, so I get excited when I see other advocates. 💙❤
Hi if you're a medical student how can I contact you??I'm releasing USMLE question and answer books in amazon tomorrow for every part of medicine and I need some reviews and some help
I don't comment on a lot of my medical lecture videos but this is a solid review with some very great ways of remembering what the neurotransmitters do. Thank you.
⚕️I appreciate the cautionary warning you put in the beginning. My professor is a little too drug-happy in her lectures and it's nice to see someone giving addiction, abuse and the sky rocketing death toll the respect it deserves. 🫡
Just an observation, in the Memorable Psychopharmacology book published back in 2017, the "DOPAMINE" Mnemonic is D rugs, O Psychosis, P rolactin, A ttention, M otivation, I nvoluntary Movement, N ausea, E nergy.
Absolutely love this video series for psychopharmacology! I am a Psychiatric Mental Health NP student and these videos are a great addition to the Stahl's textbook. Thank you very much :)
I start psychopharmacology in a couple weeks and am also a PMHNP student! My class is also using the Stahl textbook so I'm hoping I find success with these videos as well!
Neurotransmitter: A neurochemical emitted between the junction or synapse between neurons causing bio-electrical impulses to travel between neurons and increase synaptic efficiency (connectivity), and as an emergent property, comprises thinking. For cognitive and evolutionary psychologists, the bio is removed from the electrical, and the electrical metaphor is used, making the brain into a computer, neurons into circuitry, and neurotransmitters into the stuff that powers a light bulb, which metaphorically came on for the dim bulb psychologists who came up with the idea. from Dr. Mezmer’s Dictionary of Bad Psycholgy, at doctormezmer.com
*SCHIZOPHRENIA TREATMENT BREAKTHROUGH: My heart goes out to everyone who have or cares for a mentally ill person, there should be no shame. I once believed Schizophrenia or mental illness has no cure... Well, it is true with antipsychotic medicine, but not with Consummo Herbal Medicine. To be clear, there is no pharmaceutical medicine, no magic pill that has any significant effect on the progressive downhill course of this disease. My daughter's experience opened my eyes to the reality of a cure through the wonders of herbs. My daughter was diagnosed with schizophrenia many years ago... I spent more time in hospital than out of hospital. She had a major breakthrough only with CONSUMMO treatment. She has been well and living her best life. While there may be other different options to look into, never make your own success path a secret. I consider myself an advocate for people who don’t have a voice. I don't want people to feel that suicide is their only option.

3. With great power comes great responsibility: More efficacy and More Severe side effects
• full agonist mimics the effect of a neurotransmitter
• a partial agonist mimics it but only to a certain lower point
• an antagonist blocks the effect of a neurotransmitter
• inverse agonist produces an opposite effect to the neurotransmitter
Dopamine: Reward pathway located in VENTRAL TEGMENTAL AREA, Nucleus Accumbens is imp area
- D: Drive (governs motivation and reward)
- O: Psychosis (blockade mitigates some features like delusions and hallucinations)
- P: Parkinsonism (decreased secretion linked to Parkinson's pathology)
- A: Attention (boosting dopamine improves attention and concentration)
- M: Motor (strongly linked to motor function, imbalances cause conditions like Parkinson's)
- I: Inhibition of prolactin (crucial in regulating prolactin release) (prior name: Prolactin inhibiting factor)
When dopamine is blocked, one side effect is milk release from the breasts.
- N: Narcotics (release of dopamine plays a role in addiction)
- E: Extrapyramidal (controls motor functions, blocking leads to significant motor side-effects)
Serotonin: complex molecule with many roles, comes from the RAPHE NUCLEI
Also known as 5-HT (5-hydroxytryptamine)
- Head: Depression, anxiety, social interaction (sociality), impulsivity, sex drive, migraines, satisfaction
- Red: Platelet binding and adhesion, interfering with its function cause bleeding
- Fed: GI tract motility (90% of all serotonin in GI tract), nausea (serotonin blocking medications effective)
Serotonin Syndrome: 2 serotonergic drugs are taken at the same time
Head: Headache, Agitation, Confusion
Red: Flushed, warm skin (Hyperthermia, Hypertonia, Sweating, Tachycardia)
Dead: Mortality 2 to 12%
Norepinephrine: LOCUS COERULEUS origin, regulates Sympathetic nervous system
- Fight-or-flight response
- when active, Norepinephrine lots into the brain and epinephrine peripherally into the bloodstream
- Sympathetic Innervation
Central (Concentration, attention, vigilance, energy)
Peripheral (Tachycardia, Hypertension, Glucose, Essential organs)
Brain off and on switches: Gaba (off), Glutamate (on)
GABA (Gamma-Aminobutyric Acid):
- Inhibitory neurotransmitter
- "Gaba" association with a boring lecturer inducing sleepiness
- Relaxation (breathing and muscles), euphoria, no anxiety
- Drugs that enhance GABA are often used to break a seizure.
Glutamate:
- Excitatory neurotransmitter
- Association with mating for recall
Histamine: The upper brain cortex depends upon a constant stream of histamine for activation, once supply is cut off, cortex shuts down
- H for hay fever
- I for itching
- S for sleeping
Antihistamine: Itching and hay fever disappears, patient gets sleep
First generation anti-histamines: (diphenhydramine or benadryl) used for sedation as they work in both central and peripheral NS
Newer antihistamines: (loratadine or claritin) works peripherally therefore advertised as non-drowsy
Acetylcholine (ACh): opp of Norepinephrine, responsible for regulating Parasympathetic system
- A: Autonomic functions (rest and digest functions: Bradycardia, GI motility, Salivation, Lacrimation, Urination and Sexual Arousal)
- C: Contraction (neuromuscular junction) drugs that affect ACH peripherally are used against
neuromuscular diseases like myasthenia gravis
- H: Hippocampus (memory, learning, awakeness and attention), helps combat Alzheimer’s dementia, geriatric psychiatry
Opioids:
- Armed Chinese man association with the Opium Wars
• A: Analgesia (pain relief)
• R: Respiratory depression (opioids make the respiratory center in the brain insensitive carbon dioxide so death and opioid overdoses via Ondine's curse)
• M: Meiosis/ Constriction of pupils (pinpoint pupils)
• E: Euphoria
• D: Drowsiness
• C: Constipation
Thanks a lot
doing amazing work. its you and the lyrics guys that come through for people
Ok this needs an award. The mnemonics in this vid are so high yield I am high off it
Your lectures helped me ace boards and a half decade later, I still go back and watch these. Thank you sir!

What purple book?
@@only1mesabby the purple book is the ANCC guide to passing boards for PMHNP. The purple book and this book, along with the Fitzgerald course provided by my school is all I am using. Just those three items alone are enough to keep me busy.
This is terrific. I'm a psychiatrist who, as a long-standing psychoanalyst/psychotherapist, needs a refresher course. Thanks so much.
Thanks for watching! Let me know if you have any other feedback. =)
Judith Hamilton pfft Analytical psychology all the way :) Jung is the best
EW er

When you say zofran blocks serotonin, do you mean it blocks the reuptake or blocks the transmission entirely?
Brilliant!!!
Thank you!
THANK YOU!!!!!!
Thank you so much
Hello! Do you have videos on basic neurology and basic pharmacology? Great content :)))
Hi, yes we do have videos on neurology! Check out the playlist Memorable Neurology on this channel. No pharmacology videos but maybe in the future!
