Questions about cerebral cortex
Hi! Thanks a lot for your work on the cortex page. I have two questions regarding additions you made:
- While it was once thought that the input to layer I came from the cortex itself, it is now realized that layer I across the cerebral cortex mantle receives substantial input from ‘‘matrix’’ or M-type thalamus cells
This sentence doesn't make clear to me where the input to layer I actually comes from. Is the old notion that it comes from cortex completely discredited, or does most of the input come from cortex while a "substantial" amount also from thalamus, or does a "substantial" amount come from thalamus while the rest comes from somewhere else/is unknown? I suspect that my second interpretation is correct, so I would rephrase the sentence as
- While it was once thought that the input to layer I came from the cortex itself, it is now realized that layer I across the cerebral cortex mantle also receives substantial input from ‘‘matrix’’ or M-type thalamus cells
but I don't know enough about the topic to make that change.
About layer VI it says:
- Neurons send excitatory fibers to neurons in the thalamus and also from collateral to them ones via the thalamic reticular nucleus that inhibit these thalamus neurons or ones adjacent to them.
Hello LittleHow, I would like to make an addition to the Exercise Physiology page. The section would be discussing Lactic Acid buildup and both anaerbic and Aerobic fatigue. Would that be ok to do? I am an undergraduate student at Azusa Pacific University and this would be accomplishing an assignment for class. I wanted to ask permission before I attempted any drafts.
