FRAP has been used to quantify the mobility of Green Fluorescence Protein (GFP)-tagged proteins in cultured cells. We examined the mobile/immobile fractions of the GFP by analyzing the fluorescence recovery percentage after photobleaching. In this study, FRAP was performed at spines of hippocampal neurons.

Here we describe an adaptation of protocols used to induce homeostatic plasticity in neurons for the study of plasticity of astrocytic G protein-coupled receptors. Recently used to examine changes in astrocytic group I mGluRs in juvenile mice, the method can be applied to measure scaling of various astrocytic GPCRs, in tissue from adult mice in situ and in vivo, and to gain a better appreciation of the sensitivity of astrocytic receptors to changes in neuronal activity.

This video describes a protocol to obtain brain slices using an N-Methyl-D-glucamine (NMDG)-based protective recovery method. A dissected brain is incubated in an aCSF with NMDG and HEPES to minimize neuronal cell death and damage during the sectioning. The section is allowed to recover in the aCSF to restore the cellular...
FAQs
Axonal sprouting allows surviving neurons to extend new branches, while synaptic plasticity changes the strength or organization of their connections. Together, these processes can help remaining neural circuits reestablish communication after injury or disrupted signaling. Researchers examine them as complementary forms of circuit reorganization when evaluating whether structural changes are associated with improved neurological function.
Neurotrophic factors support the restoration process by helping surviving neurons maintain or improve their functional connections. Their influence is considered alongside axonal sprouting, synaptic plasticity, and remyelination rather than as an isolated mechanism. Studying these factors helps researchers identify biological processes that may preserve neurons, enhance circuit reorganization, and support better outcomes after nervous-system damage.
Remyelination can improve the condition of nerve fibers whose insulating myelin has been disrupted, supporting more effective signal transmission through affected pathways. In neuronal recovery research, it represents a mechanism distinct from forming new branches or modifying synaptic strength. Assessing remyelination therefore helps clarify whether restored communication reflects repair of axons, changes at synapses, or both.
Researchers combine cellular, molecular, and behavioral approaches to examine recovery at different levels. Cellular studies can address neuronal structure, molecular analyses can investigate processes such as neurotrophic support, and behavioral measures can indicate whether circuit changes correspond to improved function. Using these approaches together provides a broader assessment than relying on structural or functional evidence alone.
The overview identifies stroke, traumatic brain injury, and neurotoxic damage as important settings for this research. These conditions provide distinct contexts in which investigators can study disrupted signaling, neuronal preservation, and circuit reorganization. Comparing recovery across them helps researchers determine how broadly mechanisms such as axonal sprouting, synaptic plasticity, remyelination, and neurotrophic support may apply.
Evidence about circuit reorganization and restored signal transmission can guide rehabilitation strategies aimed at improving long-term neurological outcomes. Research may also support treatments designed to preserve neurons or enhance processes linked with repair. Behavioral evaluation is especially relevant because it helps determine whether cellular and molecular changes translate into meaningful functional improvement after nervous-system injury.
