简介：
Overview
This study outlines the procedures for tactile stimulation of rat pups and the subsequent Golgi-Cox staining of neuronal morphology. Tactile stimulation is administered during the perinatal period, and Golgi-Cox staining allows for the visualization of entire neurons.

What is the significance of tactile stimulation in this study?
Tactile stimulation is shown to positively influence neuronal development and morphology in rat pups.
How does Golgi-Cox staining work?
Golgi-Cox staining allows for the visualization of entire neurons, enabling detailed analysis of their structure.
What are the implications of this research?
The findings may provide insights into developmental disorders and the mechanisms of experienced-dependent plasticity.
Can this method be applied to other species?
Yes, while this study focuses on rats, the techniques can be adapted for other model organisms and human brain tissue.
