I'm just here to echo everyone else's comments and say what a fantastic video! I'm neurodivergent and I was struggling a bit with some of the complex subjects that I'm studying- including the function of synapses. I must say that this video has really helped me, it explains it clearly and with fantastic imagery. Which is exactly what my own brain needed to understand this subject! I just wanted to say thank you to the creators of this video, fantastic work and I'm extremely grateful for it!
I really never put an effort to type a comment but this time I need to say this !! This is amazingly useful to me...it made me understand the topic...I've been watching so many educational videos on youtube but I never really felt RU-vid can make our studies so cool and intresting just like a fairy tail
I'm a biology instructore from iran. I’m really keen on making the learning process easier to my students, actually i've translated and narrated some of biology animations from youtube for my students, and they were quite interested i suppose. When i was searching new animation, I suddenly came across your youtube channel (harvardX) and your exellent masterpiece (how a synapse works) first of all it has a brilliant content, and secondly i appreciate it if you help me with something. I want to translate and narrate your animation. If you give me your permission and the background music you used, it would be fantastic. I asure you its only for educational purpose. and ofcoure i will introduce my reference to them
This video just gave me so much clarity regarding the nmj and transmission of signals as a whole. Thank you so much. Helps me with the function of a contraction as well as the functions of nervous system.
Wonderful, beautiful, magnificent! I remember how much time I spent to understand physiology of excitable cells and how difficult this time was. The main obstacle was the way I was learnig - very thick handbooks, lot of pages, lot of text, little pictures and complicated terminology. Now I can watch so great videos like this and it's hard to believe how clear and logic cellular physiology is. My respect for people who make hard things more easy and clear.
Except for the part she got wrong about the axon carrying the action potential to another neuron. It's the microtublues in the axon that are responsible for axonal transport. I won't say she was WRONG, but it certainly was left out
Can you please give us the link to the "music"? I wanna reinforce the information retention by playong this on repeat on headphones during a powernap. Please share a link to the audio, please.
This complexity and neuroplasticity gives me hope people can quickly change to address our global challenges and crisis'. And the first challenge is always our own selves. Our bad behaviour, our need to become both physical and spiritual. Tree-like structures. Cleaning our "air". Thanks.
5 minutes on how neurons conduct nerve impulses make me understand better than a whole fucking 2hrs University session😁 Its an incredible animation, thanks 👍
proteins get packaged or organized in the neuron and delivered through the axon , consider the size of a rbc and the length of time it would take it to cross the length of the liver for example without BP
Can you plz give an answer of my Qs. In my book there is a line"A nerve impulse is passed from one neuron to the other neuron through synapse,but a single impulse does not necessarily get across the synapse" Why a single impulse cannot pass through the synapse??? And is only 1 impulse is generated for one action??
Hello dear Professor Thank you so much for your interesting information about Health,i do appreciate your job.I wish you peace and happness under the sky of prosperity. All the best. Take care and have a good time. Your Student from Algeria.
Thank you! Glad to hear you're interested in the course. Here is where you can learn more: online-learning.harvard.edu/course/fundamentals-neuroscience-part-1-electrical-properties-neuron?delta=1
What software is this? I wanna do that! Since I don't have the cognitive capacity to bwcome a neuroscientist, so far, I've controbuted to the field by traching English to neuroscientists and psychiatrists, but...I wanna fknd a way to do it through art...I fantasize about making a painting that a shrink will want to hang in their office...these animations are really giving me a clearer idea of how to go about it. Thank you, whoever made this...immmmpeccable animation.
When people say there are about 15000 synapses per neuron what does this mean exactly. I'm picturing 1 neuron with 15000 branches coming out of it which seems impossible. Does it mean the synapse itself branches a ton of times ultimately connect to 15000 other neurons or how does this even make sense? how many direct single connections is there to a neuron from other neurons?
like the av node being the electrical node and the sa being the chemical node, injecting a chemical into the r.atrium then igniting causing combustion , similar to fuel injection
Actually It is a Convergence of neurotransmission that Occurs by "Transmitter Gated Ion Channels" Which can be Glutamate-ergic, Cholinergic, Serotonergic, Dopaminergic, GABAergic, Amino Acid-ergic and more - These are called the Transmitter Gated Ion channel Transport, The Electrical Current is achieved by the opening of the Sodium channel (Influx) and Potassium channel (Efflux) leading to a depolarization of the Post synaptic membrane due to Na+ ions entering the intracellular matrix being greater than the K+ ions exiting the cell; Also there are "G Protein Coupled" Cascades that assist in "Neuromodulation" By Preventing Hyper-exocytotis of the Neurons thereby protecting it - All "Transmitter Gated Ion Channel Transport" Begins with a Calcium influx by the opening of Calcium channels that initiate the "Transmission Cascades" - So it is impossible to classify as Electrical or Chemical in Neurotransmission
