英文摘要
We are studying the influences of gonadal hormones on the anatomy and
physiology of the excitable cells of the electric organ, electroreceptors,
and the central electromotor pathway of the weakly electric fishes,
Mormyridae.
The electric organ produces a species-typical electrical signal, the
Electric Organ Discharge (E O D), which is important for mechanisms of
species and sex recognition. The characteristic properties of the EOD
waveform depend upon the anatomy and physiology of the electrocytes, the
excitable cells of the electric organ. We have discovered that gonadal
steroid hormones can induce a male-type EOD waveform among juveniles and
females of species with a natural sex difference in their EOD waveform. A
special set of electroreceptors, that produce spike-like receptor
potentials, show a difference in frequency tuning between natural females
and, natural males or females with a hormonally-induced male EOD waveform.
We will study the mechanisms underlying hormone-induced changes in EOD
waveforms and electroreceptor tuning with electrophysiological, anatomical,
and biochemical techniques.
We have also identified, using steroid autoradiography,
hormone-concentrating cells in the central electromotor pathway. These
findings will be extended with additional autoradiographic studies. Since
the central pathway controls the rate of electric organ excitation, i.e.
the EOD rhythm, we will examine possible differences in the EOD rhythm
between natural males and females, and hormone-treated specimens.
