I've just hunted around starting from a google for "understanding syntax" "brain scans". I've not yet found stuff specifically discussing how natural language syntax processing neural mechanisms impact our processing of computer language, but here's one that A) confirms use of some such mechanism in processing of music notation and B) suggests that such mechanisms would/can also be used used in reading, writing, understanding computer languages.
"These combined results suggest that [an area of the brain], known to be crucial for syntax processing in [natural] language, plays also a functional role in the processing of musical syntax. Hence, the present findings are consistent with the notion that Broca's area supports the processing of syntax in a rather domain-general way." (from http://www.ncbi.nlm.nih.gov/pubmed/20570253)
