Se. Asmus et Sw. Newman, TYROSINE-HYDROXYLASE MESSENGER RNA-CONTAINING NEURONS IN THE MEDIAL AMYGDALOID NUCLEUS AND THE RETICULAR NUCLEUS OF THE THALAMUS IN THE SYRIAN-HAMSTER, Molecular brain research, 20(3), 1993, pp. 267-273
To confirm previous immunocytochemical findings in colchicine-treated
Syrian hamsters, in situ hybridization was used to investigate the dis
tribution of TH mRNA-containing cells in the medial amygdaloid nucleus
(Me) and the thalamic reticular nucleus (Rt) of untreated hamsters. T
H mRNA-producing neurons were observed in anterior and posterior Me an
d throughout Rt, similar to the distribution of TH-immunostained cells
in these areas of animals receiving colchicine. These data confirm th
at TH is normally produced in amygdaloid and thalamic cell groups whic
h lie outside the classical catecholamine systems.
