Evolutionists are constantly complaining that proponents of ID do no scientific research to support their case. This is not true because there are dozens of articles published each year that support the notion of intelligent input. The support is not in the "spin" that the author puts on the data, it's in the data itself.    
   Here we have a system made up of multiple structures and multiple processes, integrated into the system and integrated into the surrounding systems in such a way that they can alter their behavior in the presence of an injury to the brain. I would like to know how this can be explained without invoking intelligent input. What kind of random, non-directed or accidental mechanism could possible accomplish this?

   Microglial cells represent the immune system of the brain and therefore are critically involved in various injuries and diseases. Little is known about their role in the healthy brain and their immediate reaction to brain damage. Using in vivo two-photon imaging in neocortex, we found that microglial cells are highly active in their presumed resting state, continually surveying their microenvironment with extremely motile processes and protrusions. Furthermore, blood brain barrier disruption provoked immediate and focal activation of microglia, switching their behavior from patrolling to shielding of the injured site. Microglia thus are busy and vigilant housekeepers in adult brain.
