==Revised Edition== 
 We have tweaked the page a bit. We have updated the language in both sections regarding blockers and modulators so as to imply specificity to small SK subtypes.  We have also revised vague and confusing language about NMDA and AMPA receptors in the LTP-related material.  Finally, we added the missing citations to the Parkinson's section and clarified information regarding what TH+ and TH- mean, phenotypically.
