This paper describes the procedures for tactile stimulation of rat pups and subsequent Golgi-Cox staining of neuronal morphology. Tactile stimulation is a positive experience that is administered in the perinatal period by stroking pups with a household duster. Golgi-cox staining is a reliable procedure permitting the visualization of entire neurons.

An imaging technique for monitoring of membrane potential changes with sub-micrometer spatial and sub-millisecond temporal resolution is described. The technique, based on laser excitation of voltage-sensitive dyes, allows measurements of signals in axons and axon collaterals, terminal dendritic branches, and individual dendritic spines.
FAQs
Label choice determines what dendritic features become visible. Stains can reveal overall neuronal morphology, whereas fluorescent markers and genetically encoded proteins provide signals that can be imaged with light microscopy; electron microscopy offers a different imaging context for examining dendritic structure. Selecting among these approaches therefore depends on whether the study emphasizes arbor organization, spines, or structural detail.
Optical sectioning separates image information from different depths within a specimen. Researchers can use the resulting sections to reconstruct dendritic arbors in three dimensions rather than relying only on a single projected view. This approach supports clearer assessment of branching organization and spatial relationships, making structural analysis more informative than a two-dimensional image alone.
Visible dendritic arbors, branches, and synaptic spines provide structural information that can be considered alongside connectivity, synaptic organization, and activity. This comparison places neuronal shape within a broader functional context. As a result, visualization helps researchers investigate how structural arrangements may relate to communication between cells and changes in circuit function.
Stains, fluorescent markers, and genetically encoded proteins provide alternative ways to label dendritic structures before microscopy. The selected labeling strategy determines how arbors, branches, and synaptic spines become detectable in the resulting images. These options allow investigators to align the labeling approach with the structural features and imaging method most relevant to the study.
A basic workflow applies a stain, fluorescent marker, or genetically encoded protein to label neuronal structures, followed by imaging with light or electron microscopy. When three-dimensional information is needed, researchers acquire optically sectioned images and use them to support reconstruction of dendritic arbors. The resulting representation can then be examined for branches, spines, and organization.
The images can document dendritic arbors, branching patterns, and synaptic spines, while three-dimensional reconstruction adds information about their spatial organization. These structural observations help researchers relate neuronal morphology to connectivity and synaptic organization. When considered with activity, the results can also provide context for understanding how anatomy relates to circuit function.
Dendrite visualization is useful when researchers need to examine structural changes across neural development, synaptic plasticity, neurodegenerative disease, or responses to drugs and injury. Comparing dendritic morphology across these conditions can reveal how arbors, branches, or spines change. Such findings help connect cellular structure with altered connectivity, synaptic organization, and circuit function.
