# STEROID INFLUENCES ON NEURONS INVOLVED IN BEHAVIOR

> **NIH NIH R01** · UNIVERSITY OF CALIFORNIA LOS ANGELES · 1993 · $150,654

## Abstract

Castration reduces the dendritic length of androgen-sensitive
motoneurons in the lumbar spinal cord of adult male rats.  Androgen
treatment reverses this effect.  The proposal is to inject
horseradish peroxidase intracellularly into these motoneurons and
measure the size and shape of the dendritic tree under high and low
levels of androgen.  We will also measure various
electrophysological characteristics of the neurons as a function
of androgen level.  These studies will clarify the cellular basis
of androgen-induced neural plasticity in adult mammals.
