 Not sure what you are looking for.  Maybe just a medical or technical
dictionary rather than full articles?  For example, "fasciculus" is a
very general neuroanatomic term (I believe related to the Latin for a
bundle of sticks, from which we also derive "Fascist"!).  It refers to
a bundle of nerve fibers, further specified for specific examples: for
example, "fasciculus retroflexus" which is (in rats, anyway) at a
startling oblique angle to major longitudinal tracts (but nowadays
named for its origin and target, i.e the "habenulopeduncular tract",
from the habenula to the cerebral peduncle); for another, the "uncinate
fasciculus", etc.

There are, of course, many articles on the cingulate cortex; including
some which are not about the cingulate at all but about the rat
homologue of prefrontal cortex--before its identification by tracing to
the mediodorsal nucleus of the thalamus, it was misidentified as
cingulate because of its gross position in the rat brain (medial, just
above the corpus callosum).  Look also under "limbic system", of which
it is a part.

Procaine is in quite another realm, of course, being a local
anesthetic--which, however, has some central effects, possibly
instigating psychomotor seizures.  Some people sensitive to it can feel
"spacey"/depersonalized etc. when  given it for surgical or dental
procedures...  ditto lidocaine...  Why not search a library or
literature database for these terms?

What does "QE" stand for?

Mydriasis is dilation of pupils, e.g. in response to a drug.

Hmmm...  Have you been annoying your cingulate cortex with procaine,
and does it show in your eyes?!?
