Neuroplasticity | Nervous system physiology | NCLEX-RN | Khan Academy 

RU-vid is the best teaching university on earth.

Leave it to Khan to be the only ones on youtube, or the internet for that matter, to explain this well.

I'll be dedicating my degrees to RU-vid. 😂 Thanks for this vid! Your content is ALWAYS helpful.

I am in a six years post-stroke AND my body and my brain and my collection of an accents are doing amazing.

The human body is so crazy complex.

Wow! Thank you thank you thank you🙏 Wish me luck with my exam tomorrow

Hello, I'm a medical engineering student and I want to do my dissertation on the analysis of neuroplastic changes in the brain when learning. This sort of information is exactly the background I want to learn, can you make more of these videos? Also did you get this info from a book? If so what book? Can anyone recommend any books on neuroplasticity and synaptogenesis?

Thank you for the amazing lecture. Love your videos.

I am thinking that, even if the discovery of neuroplasticity is something very interesting and potentially useful, is not something we already knew from experience? If we stop seeing a person, our feeling of connection with him or her diminish with time. The same if we stay long without practice tennis, we loose abilities.

what a banger my g

@JackVegas Tv: black backgrounds are said to be more "restful" for the eye and have been recommended for slideshows as a result (there was a TED talk on this).

I have a question why negative neuroplasticity is faster than positive, I mean if a person has a large impact or trauma from post-traumatic stress, their neuroplasticity changes negatively in a moment of shock and why positive neuroplasticity takes much longer to recuperate ?

Thanks !!!! From Chile.

Why They are Called Potentiation and Depression? Are They related to depression like feeling of sadness

Super interesting and so well explained! Thank you so much!

very interesting!! important for the general public to know. so many frustrations in life come from bad habits that are rationalized with outside factors. if we think emprically, we'll be successful and happy!

You have a nice calm way of speaking. I think i'll learn a lot.

Many thanks. Could the structural potentiation result in a neuron connecting to a totally different neuron?

Excellent explanation 👌 thank you!

This is a very incredible organ. That is why psychology in my opinion has left out some variables that play into diagnosing actual mental illness that is purely physiological- because beliefs that were ingrained especially in early childhood, whether true or false, play into what we become like in adulthood. So some people may be diagnosed as mentally ill or emotionally unstable- lets use a mood disorder for example: Its important I suppose to ask, "Is this purely physiological and can it be fixed with just medication, or is it a divided mind (our thoughts are very closely tied to emotions) so if a person seems to have many mood swings then it may be that at an hour ago they may have been thinking thoughts condusive to a positive mood, vs an hour later a minir experience (possible misread situation with another person) could lead them into a pattern of thought that creates a negative corresponding emotion. Paranoia is often created out of experiences from my experience that reinforce often false suspicions. Some suspicions and distrust is warranted from some people yet if a individual has gotten so hosed up to the degree their negative life experiences have created a trigger that could set an alarm off to anything they remotly associate with a (negative feeling they have, insecurity or emotion)

The PNS isn't that plastic. CNS is where the majority of neuroplasticity occurs

good

There are actually how many types of neuroplasticity? cause i found something that is functional plasticity and reparative plasticity

I am suffering from a Lexapro withdrawal and have been kindled with many failed reinstaments. Is there hope for me?

Are NEW STRUCTURAL SYNAPSES actually CREATED when we change or alter thought habits and experiences or are we BORN with all the neural pathways already and simply by changing brain habits and experiences are we merely UTILIZING already EXISTING neural pathways? Do we just access neural pathways that are already there or do new thoughts and experiences actually CREATE new neural pathways? Depending upon the answer to the above question, then if a neuroscientist were to be looking at a brain scan or an autopsied brain, would she see all the neural pathways that both had already been utilized as well as the ones that were never used?

i'm a pharmasist and my graduation project is about dopamine and it's connection with addiction and there's alot of neuroplasticity in every thing i read and i needed this video to understand more about brain and connection and how drugs can make changes to the synapses and cause addiction.so thanks alot .. please make more vedios about this 🤓❤ and if u can advice me with some books or websites about that i would be very thankful...

So what's the difference between cooperative adns tructural potentiation? I mean physiologically. I get it that in the abstract, an association of two ideas, like mnemonics, can facilitate and accelerate potentiation, but...is increased structural potentiation then just caused by coopoerative action potential in the pre-synaptic neuron? Another question is how much control do we really have over these associations? You know what I mean? In terms of synaptic depression..let's say you wanna get rid of some ptsd flashbacks...how strong of a trigger and what number of triggers may there be to repeatedly awaken these seemingly senascent (I can't spell it...dormant) synapses? They might be endless....I mean, once those instense experiences have tangled themselves into all those different neurons, it might be impossible to completely isolate those engrams and never ever activate them again...sooo, I guess my follow up question is - how do we decrease the amount of that Na,Ca charge? I mean, if I try not to think of a pink elephant, I'm still thinking of not thinking about a pink elephant, which is technically thinking about a pink elephant...I'm not sure this knowledge is that beneficial to laymen..in fact, it might be detrimental, as it keeps reminding me of things I don't wanna think about and things I don't wanna be doing...which seems to increase the chance of me thinking about them and doing those things...right now I'm talking about cigarettes, but it could be porn, or gambling or weed...or junk food...or even anger...

Amazing job! thank you very much ..keep going ❤

Excellent

Brilliant.. thanks so much

whos here for online school

Brilliant absolutely brilliant

How can I cite this?

Thank u!

Really captivating stuff!

Nice explanation. Thanks

tnks ❤🤓

thank you

So dang cool!

why would one not correlate depression as a state with depression as the decrease of information or communication between neurons? it would seem that the two would be directly correlated

Thank you very much for the video. It was very clear, precise and well structured!
