3 Facts: The outside of the membrane is positive and the inside is negative because of the potassium sodium pump. Action potential triggers voltage gate calcium channel to open so synaptic vessels can fuse with it which sends out neuron transmitters. DHA increases the elasticity of the calcium voltage gate which makes the vessels and neurotransmitter diffuse easier and faster, increases speed of neuro-transaction. Questions: Why do the neurotransmitters pop off and is it significant if they either re-uptake, diffuse or degenerate? What is outside stimulus in relation to the mechanical ion channel? Action potential?
1. The Connection: In my video, I touched briefly on the topic of neurons and synaptic impulses. Charlie's whole video covers synaptic transmission and relates very heavily with my explanation of the anatomy of the neuron. I talked about the function of the axon, dendrite, and stoma. In this video he is giving a in-depth molecular function of how the axon functions. Charlie also gives an in-depth explanation of how the synaptic cleft functions with the synaptic vesicles to transfer information from neuron to neuron.
2. Questions: a. Since there are tons of neurons condensed in one area and the electrical impulses can't be touched with others, how does the synaptic celft maintain stability of the separation of the axon terminals?
b. How does the elasticity-diffusion in the neuron originally function and what process allows DHA to effect the elasticity by speeding it up?
Similarity: The part where you talked about how the Omega-3's make up a large portion of the membrane was closely related to what I discussed in my video, especially when you talked about how it makes the membrane more flexible. We both agreed that it was highly important for there to be a high flexibility for the membrane to be flexible in order for the neurotransmitters to work well, and thus for electrical signals to be transferred well.
Questions: 1. What type of outside stimulus causes the process to start? 2. Does the amount of neurotransmitters sent across the synaptic cleft change the "message" or is it just an "on" type signal?
Charlie, I love how you took illustrations and graphics and just talked. The diagrams you chose were easy to follow; your descriptions flowed well and were easy to understand.
Some areas to develop: (1) Are certain neurotransmitters/synaptic characteristics more affected by omega-3s? (2) Could you give a little background about neurotransmitters? Name a few - state where they are produced - describe what they control. I think someone else is covering this too, but I can't remember who.
Overall, a good job. You did a good job talking clearly so you were easily understood.
