    Most beautiful educational video I've seen in years.no colorful clutters no unnecessary intros words rumbling, better than khan academy. I needed explanation on what happened before during and after LTP outside, inside and around neurons, and you answered all of it in a calm, beautiful, soundy way. i needed references and you supplied it in the description. this channel is so underrated 🥳🤯🙌🏼

    this explanation is so much better than many I watched. it is simpler and at the same time deeper. it seems coming from a person who REALLY understands what she is talking about. Thanks for a great presentation. Now I have a better idea of what's going on in how the memories are strengthened.

    There are calcium permeable AMPA receptors as well! Not only NMDA. This is important for plasticity!!

    • @BioBrainBuddies
      @BioBrainBuddies  ปีที่แล้ว

      Yeh you are right! Both of these receptors are very important for neuroplastic growth!

    I´ve watched it like 3 times and every time I do so it´s even clearer to me the mechanisms that result in LTP (early or late fase).
    u have a talent. this video is the result of great educational skills combined with great editing skills. thank u

    1.NMDA 2A subunit...,2B...utilizes for formation of LTD.
    2.NMDA 2A receptor is also having Glycine...which detatch during the electrostatic repulsion phase..
    3.NMDA also acts as "*coincidence detector*" as it can sense both pre & post synaptic changes..
    4. CAMK II not only helps to translocate more AMPA rec at post syn area but also helps in retrograde release of neurotransmitters like NO, CO & Endocannabinoids....altogether they increase AMPA rec CONDUCTANCE...gradually in Eaerly phase of LTP.
    5.In late LTP not only AMOA, NMDA rec take part but also PI3K & mGluR get activated....ultimately via CREB gene & ERK pathways....BDNF, PSD 95 genes are synthesised....and help to store memories in cerebral cortices....

    So the condition of opening NMDA receptors is the depolarization of the postsynaptic shaffer collateral neuron. What causes the depolarization that causes the influx of Na+?

    • @BioBrainBuddies
      @BioBrainBuddies  8 หลายเดือนก่อน +1

      Hey there! So, the depolarization of the postsynaptic neuron happens when glutamate (a neurotransmitter) is released from the presynaptic neuron. This glutamate binds to NMDA receptors on the postsynaptic membrane. However, for these receptors to fully activate and allow Na+ influx, the postsynaptic neuron needs to depolarize, which typically occurs due to the opening of voltage-gated sodium channels triggered by other neurotransmitters or electrochemical events. It's like a key (glutamate) unlocking a door (NMDA receptor), but the door only opens when there's enough energy (depolarization) to push it open. Na+ Influx occurs by diffusion as there is a great concentration of Na+ outside compared to inside the neuron. Hope that helps clarify things!

    Really good video, thanks! I have been reading a lot of source papers on molecular basis of memory. But my knowledge of the dynamics is pretty patchy from just those. So nice to have things displayed visually like this!! Id just note that when you say "weaker action potentials can then lead to greater depolarisation" I assume you are referring to summation from a smaller than usual number of pre-synaptic inputs can lead to depolarisation (given there are potentially hundreds or thousands of inputs to a single post-synaptic neuron)? Rather than the actual strength of a given action potential from one presynaptic neuron (which is always the same for a given pre-synaptic neuron).

    • @BioBrainBuddies
      @BioBrainBuddies  7 หลายเดือนก่อน +1

      Thanks for watching our video Francis!
      You are right! I was explaining summation and how even smaller AP can lead to depolarisation.
      Do you have any other topics you think is in need of explaining within memory?

    While spiraling down into the rabbit hole of deviating from the initial question review for my STEP 1, I came across this gem of a video!! Amazing work, great quality and content!! I will look into more of your content. I just hope LTP is real and it help me recall that Mg only blocks NMDA (and not AMPA) receptors at resting membrane potential. 🤖

    • @BioBrainBuddies
      @BioBrainBuddies  2 ปีที่แล้ว +2

      Hey, I'm glad you enjoyed the video! The Na outside the cell is maintained through the resting potential Na K pumps. So after the action potential these pumps with pump out the Na from the cell while pumping K in

  • @daydaysports
    @daydaysports 2 ปีที่แล้ว +2

    The mg+ is expelled from the NMDA due to the Na+, Then Why Ca+ which is + can go in through the NMDA as so many Na+ in the post synaptic neuron?

    • @BioBrainBuddies
      @BioBrainBuddies  2 ปีที่แล้ว +4

      It expells the Mg+ based on the relative positive charge provided by the Na+, the neuron still has the graident to allow both Ca+ and Na+ to enter but it just happens quicker. Just because the Mg+ was expelled doesn't mean the postive-negative gradient has met equilibrium. At least this if from my understanding.

  • @leusmaximusx

    your video did not address the fact on how knowledge (picture) as information parts (jigsaw) as binary 01 combination form is stored in the individual neural potential bed (the so called Read only memory , ROM chip) of the neuron. This is what Long term memory is on our brain.
    Each neuron contains only a portion of that picture (which is the information) , like a part or a jigsaw puzzle.
    interconnected neurons (each containing jigsaw parts of the information) through synapses, is like assembling the jigsaw parts near to its associated meaning full order to resemble the original picture.
    When a trigger stimuli enters the brain , the hippocampus evaluates the stimuli and creates a mimic picture in form of signals of specific frequency that will fire across the cortex .
    Once a existing receptive neurons are hit by the signal , it will light up and fires up the the interconnected neurons causing all to increase potential from rest state.
    This is similar to close fitting the jigsaw parts to form the whole picture of the knowledge stored for use by the mind (operator)
    I hope to the above process visualize in your succeeding videos .
    Thanks

      @chaneltink471 ปีที่แล้ว

      Yes you're right! This was very briefly touched on in the Hippocampus video where it explains that, when retrieving a memory, this firing pattern would appear as a cortical representation of the memory [I.e the bits of info stored in the neurons across the cortex will fire like a cortical representation]
      Super cool stuff!
