    Calcium Voltage
AI Thread Summary
The discussion centers on understanding voltage-gated calcium channels and their role in action potentials. It highlights that when an action potential reaches the presynaptic terminal, it triggers calcium ion entry, which is crucial for neurotransmitter release. The conversation emphasizes the importance of calcium ion recycling during this process, mentioning mechanisms such as the Na+/Ca2+ exchanger and Ca2+-ATPase for calcium extrusion. While resources on sodium and potassium channels are abundant, there is a noted scarcity of materials specifically addressing calcium channels. A recommended book chapter and several articles are provided as useful references for further exploration of these topics.

Referring to following video, I would like to know more about voltage gated calcium channels, will this process called action potential? How do Calcium ion recycle during this process?

I can find a lot of materials on action potential for Na+/K+ pump along axon, but not much materials talking about calcium channels.

Does anyone have any suggestions?
Thansk in advance for any suggestions

Edit: Another crackpot link removed.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
