Abstract
The diverse morphologies of catecholamine axons in the human brain were examined by
using tyrosine hydroxylase immunocytochemistry. Human brain tissue was obtained by
either rapid autopsy (mean postmortem delay < 1 h) or routine autopsy (mean postmortem
delay 5 h). Tissue blocks from the superior frontal cortex (Brodmann area 9), the
hippocampal gyrus and the calcarine cortex (Brodmann area 17) were processed for tyrosine
hydroxylase immunoreactivity. First, a quantitative method was developed to reliably
identify differing morphologies of catecholamine axons in human brain tissue. A total
of 625 tyrosine hydroxylase immunoreactive axons were randomly sampled from coded
sections and classified into one of six distinct morphological categories. These categories
were based upon axonal morphologies which were readily distinguished by trained observers,
and moreover, further investigations demonstrated that entire tissue sections could
be reliably re-sampled at intervals of up to six months. Second, regional variations
in axonal distribution and the effects of increasing postmortem delay in tissue processing
on the categories of tyrosine hydroxylase immunoreactive axon morphologies were examined.
Postmortem delays of up to 6.5 hours were found to decrease the frequency of fine
axons with varicosities (axon type 2) and increase thick-caliber straight axons (axon
type 5) in all regions examined. The frequency of other morphological axon types did
not change as a function of postmortem delay. In summary, the use of quantitative
neuroanatomical measures of the catecholaminergic system in human brain tissue was
found to be reliable and valid. It was furthermore demonstrated that postmortem delays
affect selected morphological types of catecholamine axons. These results indicate
that interpretation of immunostained human material must include careful consideration
of the effects of postmortem delay on immunoreactive axonal morphology.
