It all depends on whether you are using the terms as "count nouns" or
"mass nouns" and it can be quite subtle.
For example, as mass nouns your might say "Cortex [amygdala] was
observed" meaning some amount (not countable, although possibly
measurable). As count nouns you might say "The cortex [amygdala] was
observed" meaning a countable number (e.g. just one).
