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?
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
