6. "Systematic mapping between areas of the visual field and areas of the cortex/other brain regions"...?

  • Ocular dominance
  • Retinotopy
  • Tonotopy
  • Cortical mapping

7. If there are denser arrays of neurons in a region of the motor cortices...?

  • They have larger ocular dominance columns
  • They have a higher capability of exercising fine motor control
  • They have larger receptive fields
  • They have larger cortical representations

8. What are lateral connections assumed to have?

  • Centre-on, surround-off
  • Centre-off, surround-off
  • Centre-off, surround-on
  • Centre-on, surround-on

9. Neurons tunings are spread...?

  • Across the space of the input with troughs near the centre
  • Across the space of the input with dense coding near the centre and sparse around the periphery
  • Evenly across the space of the input
  • Across the space of the input with peaks near the centre

10. Are maps only restricted to primary cortices?

  • No, they are just harder to find as neurons past the cortex dont respond to simple/motor variables. Their responses can be hard to pinpoint
  • Yes. as these receive the main inputs from the basic senses and so have well defined maps

11. Physically adjacent units to the winning updating cells...?

  • Mirror the winning cell
  • Mirror facilitatory cells
  • Come to represent similar input patterns
  • Represent opposite input patterns

12. In the somatosensory cortex...?

  • Body parts which are more densly arrayed with receptors e.g hands are afforded more space than less sensitive regions e.g shoulder
  • Effectors which are subject to fine motor control e.g tongue, lips, hands, are allocated more space in the cortical map

13. Which are accorded more space in the map?

  • Similar input patterns that occur frequently
  • Unusual input patterns that occur frequently
  • Unusual input patterns that occur infrequently
  • Similar input patterns that occur infrequently

14. In the motor cortex...?

  • Effectors which are subject to fine motor control e.g tongue, lips, hands, are allocated more space in the cortical map
  • Body parts which are more densly arrayed with receptors e.g hands are afforded more space than less sensitive regions e.g shoulder

15. What did original studies of retinotopy rely on?

  • EEG
  • Lesions
  • TMS
  • fMRI

16. Which of these is a limitation of fMRI?

  • Not detailed enough for small structures, those less than
  • Non-invasive
  • Whole brain can be recorded
  • Blood flow and water content measures

17. What doe the properties of lateral connections afford?

  • Physically close neurons facilitate each other, distant neurons inhibit
  • Physically close neurons inhibit each other, distant neurons facilitate
  • All connections are facilitatory
  • All connections are inhibitory

18. What is meant by a self organising map?

  • After weight updating from competitive learning, neighboruing neurons also update. The physical layout of the network affects learning
  • After weight updating from supervised learning, neighboruing neurons also update. The physical layout of the network affects learning
  • After weight updating from unsupervised learning, neighboruing neurons also update. The physical layout of the network affects learning
