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?

  • A mirrored curve
  • The curve shifting to the right
  • The curve flipping
  • The curve shifting to the left

11. What is contrast?

  • The levels of shadow in the visual field. Expressed as a decimal or percentage
  • The amount of light in the visual field. Expressed as a decimal or percentage
  • The luminance variation in the visual field. Expressed as a decimal or percentage
  • The amount of light reaching the retina. Expressed as a decimal or percentage

12. What is a transducer function (Nachmias and Sansbury, 1974)?

  • How a neuron generates an action potential
  • How a neuron carries a signal
  • How a neuron converts input to output
  • How a neuron receives input

13. What is the correct process?

  • Retina -> LGN -> cortex

14. What was found by Bonds (1989) using masks?

  • Neurons maintain ability to code differences by shifting sensitivity to the average
  • Neurons maintain ability to code differences by shifting sensitivity to the highest point
  • Neurons maintain ability to code differences by shifting sensitivity to the lowest point
  • Neurons maintain ability to code differences by not shifting their sensitivity

15. In typical people...?

17. What is gain control?

  • How many variables a neuron can respond to with a single train of action potential luminance, contrast, blur
  • Lets neurons control their sensitivity e.g luminance, contrast, blur
  • A set range of sensitivities a neuron can respond to e.g luminance, contrast, blur
