I'm just a casual viewer, so where in our DNA is the information stored that allows for such complex structures? What motivates all these things to be built in the first place when you are an embryo? Wouldn't some kind of script have to designate all this in 3d space? What mechanism oversees that every cell has exactly the right amount of gap between each actuator??
Thank you. Because my professor SUCKS, I could not, for the life of me, figure out what excitatory and inhibitory effects meant. Sucks when she makes her own book and never even defines it.
what?... like i think im the only person here thats not a student so the scientific terms almost made the hole video go strait over my head here. infact if there wornt pictures id think this was another language. i feel a littel stupid watching this
this video is the only method that worked with me! I've tried many other sources in order to understand EPSP and IPSP and they all failed. thanks so much
This video is mandatory viewing for my fellow benzodiazepine withdrawal sufferers, as few of us (including the vast majority of physician's who prescribe Xanax, Klonopin, Ativan, Valium, etc.) understand the electro-chemical process (E & IPSP) which is responsible for an insane degree of excitatory synaptic issues and a long list of quite horriffic symptoms upon removig the benzodiazepine. Very happy to find these neuro posts! Thank you!
Thank you soooo much for this video; I'm taking Biopsych and it's so nice to actually "see" this process (instead of reading a wall of text in a textbook) :D
@atph120890 What basically occurs is that, when stimulated, Na+ rushes into a polarized cell raising the charge to about +20-30 mV. Then K+ leaves the cell in an attempt to restor the polarity-which it does. After that the Na-K pump restores the two Ions to their correct quantities on either side of the membrane. The Na+ rushing in in one area stimulates the action potential in an adjacent area- all the way to the synaptic cleft. This is faster when the axon is sheathed in myelin (Shwann cells)
As far as I can see it at 1:20 the video conveys wrong information. One synapse can only emmit one spcific transmitter (the video shows different coloured transmitters). So one synapse is either be inhibitory or excitatory but not both at the same time.
@Seas00Gurl The Synapse is the whole combination, the Synaptic cleft, the Presynaptic membrane of the Axon and the Postsynaptic membrane of the Dendrite. The synapse cleft is only the 'gap' between the two membranes. Good luck!
Maybe I am missing something - but at the end doesn't this say (2:23) "post-synaptic potentials cannot travel far..." and then (2:33) "however, post-synaptic potentials travel far enough to reach the cell body" - surely that is a mistake...
what they mean is that PSPs dont travel very far, but just far enough to go from dendrite (where the receptors are) to the cell body. it does not need to travel any further than that, because at the cell body, MANY such tiny signals are integrated. then it is decided whether or not to fire an action potential.
I think what they're trying to say is that although post-synaptic potentials cannot travel far, they travel far enough to reach the cell body. Since this video is referring to axon-to-cell-body interaction (aka. axon-to-soma), PSP is in fact traveling just a short distance, enough to reach the soma. So they meant what they said. I hope this makes sense.
@dragonfry What is meant by this is simply the postsynaptic potentials, either EPSPs or IPSPs are not sufficient to travel on there on down an axon as an active signal thus passively diffuse their charge far enough oonly from the dendrite to the cell soma where if sufficient EPSPs are present, they are graded into an active signal, called an action potential, at the axon hillock whereby this active signal actively conducts along the axon to reach the nerve terminal.
I seem to be a little late to your comment... If no has answered it, let me take a whack at it.
PSP cannot travel far, so they can only diffuse into the cell, and not to other cells, and the synapse distance cannot be too great. So, it can travel far enough to reach to cell body, but not so far that it gets to the other side of the cells or nearby cells. Plus once the chemicals reach the dendrites it may start off another wave, meaning that the chemicals do not have to travel far.
@dragonfry Its true, post synaptic potentials can't travel very far, their transmission is dependent on the use of leak channels since there are no voltage gated channels on the cell body of a neurone - therefore the signal diminishes as it crosses along the neurone. The PSP signal is strong enough to reach the cell body but not the axon (which is what I think you're getting confused about). Collectively the PSPs from other synapses will summate at the cell body causing an action potential
Nice video, could have gone into more details on EPSP's and IPSP's, i.e NA= and CL- channels etc...but a great summary nonetheless: Visuals help a great deal
It was great and helpful video. However, I thought you were to fast when you talk, it would be perfect if you slow down a little. Thx any way
