Syslog is from logging, which is usually based on the level you set (informational, emergencies, alerts, etc.) but can also be configured based on "facility" (technology).  Logging can be directed at different types of output depending on how its configured.

Debugs are technology specific (e.g., "debug ip icmp" or "debug crypto isakmp") and only show up when you turn them on. Debugs are very helpful but care is needed because if you debug too broadly (e.g., "debug ip packet") you run a high risk if causing problems with the router.

Take a look at http://www.ciscopress.com/articles/article.asp?p=101658&seqNum=3 for a little more information.
