Anyone here knows some pharmacology? When people say something like "dopamine receptor agonist"...is the receptor presynaptic or postsynaptic? A presynaptic receptor (e.g. autoreceptor) may trigger a decrease in the production of the neurotransmmiter (so an inhibitory response), while an agonizer for postsynaptic receptor may encourage firing (so excitatory).

Am I misunderstanding something?

>So then what kind of information does "dopamine receptor agonist" and "dopamine receptor antagonist" impart? If you don't know what kind of receptor it agonizes or antagonizes, how can you know what kind of effect it has?
By looking at the particular receptor it binds to. Clonidine agonises (presynaptic) alpha_2 receptors, which are autoreceptors and their agonism therefore causes a decrease in adrenergic activity, whereas, say, oxymetazoline is a (post-synaptic) alpha_1 agonist so its agonism increases adrenergic activity.
>>
>>9251576

Yes this is correct. Agonist means it binds to and 'activates' the receptor. Antagonist means it binds to the receptor in such a way that it is not 'activated' and can't be bound by an agonist. Agonists and antagonists can both be responsible for excitatory or inhibitory stimulus.
>>
>>9251628
The agonist can act on either a presynaptic or postsynaptic cell. It's post-synaptic if it acts on the dendrite, and pre-synaptic if it acts on the axon terminal
>>
>>9251634
>By looking at the particular receptor it binds to.
Yeah, but even then, 5-HT1A receptor in the raphe nucleus is an autoreceptor and in the hippocampus is a postynaptic receptor.. In this case, I guess a 5-HT1A agonizer would inhibit serotonergic neurons in one part and excite them in another. But yeah, my confusion was related to the fact that "serotonin receptor agonist" without any further information provides little information

i was given a task to model magnetic fields of permanent magnets with comsol multiphysics
i created two magnets having certain sizes,then i defined materials for the magnets and an environment where the magnets are located. also i defined relative permeability and density for the materials . then i chose modul AC/DC and chose magnetic field no currrents, set arbitrary magnetization, of course i defined magnetic insulation.
in study with stationary researching i clicked compute and got bullshit. as on the picture.
who knows how to get a good result? what do i do wrong?

Alright ya noobs, I'm settling this time travel hoax once and for all.

First and foremost: Time is an arbitrary notation created by man. If the whole concept were to die out, none of our (correct) maths would be any different. All you're giving meaning to is MOTION. Same with energy, there is no such thing, just different forms of motion. Kinetic energy is a pleonasm.

Now back to time. How the FUCK would you translate said arbitrary time notation to a machine somehow connected to space-"time"?
Pro tip: You can't.

>Time is not a physical "thing" in the universe. It's an abstract concept to give subjective meaning to motion. Time is meaningless in the universe. There is no time quantum.

Unless you manage to install a framework in the universe with a functional API it's not happening. Yes, mass and speed (same thing) slow down motion but that's it. You can slow down your RELATIVE MOTION as opposed to others but that's not time travel. There's no destination as defined by con-artists getting grant money for fake/stupid study and spend it on booze and cocaine (like my money).

Get over it. There's no such thing as fucking time travel.

Also, time TRAVEL implies a destination. Beyond our high level, abstract communication method (which I'm not fond of either). Tell me, where exactly is next week? or last week? Break out the maths faggot, oh, you can't. Because even Einstein didn't predict destination-based time travel. And none of his maths allow for a stable "wormhole".

Checkmate muggles.

Holograms can be cut into as many little pieces as you like and they will all have the same image. Kinda like how when you divide a magnet, it just turns into two smaller magnets and so on. It couldn't possibly be because light is somehow dependent on MAGNETISM and DIELECTIC INERTIA.

So these two things already blow the fuck out of any perceived "boundary" the universe has. It never began nor will end. 0 IS THE PLACEHOLDER, 1 IS THE PRINCIPAL.

>0 is the placeholder
You cannot derive something out of nothing. Such nonsense is for atomists who believe some magical special snowflake particle spawned the entire universe.

>1 is the principal
You cannot have everything at the same time for that would mean NO CHANGE occurs.

There are thousands of books on this, Plotinus would be a good start though.

>quantum gravity

Yeah lets just stick the word "quantum" in front of things and then make it completely. Gravity is no different then what most people call "magnetic attraction, magnetic repulsion". There is no attraction or repulsion in a magnet, it creates counter space that follows the right hand rule.

Actually......
Classical has a much easier display of musical theory to get a hold of, so it is really good for a beginner to listen to. Baroque is also good for tonality and scales, and romantic is great for dynamics and rhythm (and understanding chords I, IV, and V - Romantic was blues for French Aristocrats). The reason I say this is because it is super easy to explain why Ode To Joy sounds good in comparison to a soulful blues song. It's really complex to explain but tl;dr, if you want to learn music theory, historical listening progression is the best.

No problem man. It's a long road, and it's tough and demoralizing, and it's really easy to want to quit. Especially when you take requirements like English and get a 4.0 effortlessly, and then struggle just to get a 3.2 in a STEM course with a tough curve. Makes you wonder constantly if you made the right choice. But just find something within your field for right now you're passionate about, and use that to tune out any negative feelings, because you know rationally that if you keep on the straight and narrow, it'll get better in the end.

Don't give up fampai. I'll remember you and cheer you on, even if we never cross paths. Hell, if you keep posting maybe we will. Maybe we'll get into an argument and fling insults at each other. Maybe we'll agree with one another and support a discussion with evidence and arguments we've picked up recently. But for the time being, just know that there's someone out there who honestly, in the bottom of their hearts, wants you to succeed and find happiness in life.

Good night, brother, and may you, stumbling through this dark and meaningless abyss, find or create your own light and meaning.

Anyone here good at math and good at being a musician as well?

Math was my worst subject in school...I couldn't understand anything beyond basic algebra. I am also a musician (oboe for over 25 years), but have the sense of rhythm of a brick.

Is there a correlation between math and music ability?
>>
I know that Pythagoras and Riemann were interested in music theory. I don't know how well they played music. I'm guessing maths and musical ability might be correlated in the sense that it both attracts people who think abstractly. Then again maybe there's something in playing music that just attracts creative people, artists or music lovers who are satisfied without knowing (much) theory.
