| Summary |
|
|
|
|
|
| • | Early
morphological specialization of DRG neurons |
|||
| sets stage
for separate mechanosensory and |
||||
| pain/temp/itch
systems |
||||
|
|
|
|
| • | Different
ascending pathways to distinct subcortical |
||
| and cortical
sites |
|||
|
|
|
| • | Single
thalamic mechanosensory nucleus and 1° ctx |
|
|
|
|
| • | Multiple
thalamic pain nuclei and cortical areas |
|
|
|
|
|
| • | Parietal lobe
projections may play role in stimulus |
||
| localization,
esp. for touch |
|||
|
|
|
| • | Cortical pain
representations closely tied to emotions |
