6. In the dipper function...?
- Sensitivity is proportional to the slope of the curve and adding a mask shifts the dipper to the right
- Sensitivity is proportional to the gradient of the curve and adding a mask shifts the dipper to the left
- Sensitivity is proportional to the slope of the curve and adding a mask shifts the dipper to the left
- Sensitivity is proportional to the gradient of the curve and adding a mask shifts the dipper to the right
7. According to gain control...?
- Modularity can be expressed via local averages in localised parts of the cortex
- Neural activity is moderated by the local activity of the group across time and space
- Modularity can be expressed through local averages
- Neural activity is a poor indicator of cognitive function
8. What indicates a PERFECT function in gain control?
