Overview Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body. Structure and Function of Neurons The neuronal cell body—the soma— houses the nucleus and organelles vital to...

This article describes a working protocol to image dendritic spines from hippocampal neurons in vitro using Structured Illumination Microscopy (SIM). Super-resolution microscopy using SIM provides image resolution significantly beyond the light diffraction limit in all three spatial dimensions, allowing the imaging of individual dendritic spines with improved detail.

To understand the structure of neuronal networks, functional and morphological characterization of individual neurons is a necessity. Here, we demonstrate juxtasomal biocytin labeling, which allows electrophysiological recordings in the extracellular configuration, yet maintaining the ability to intracellularly label the neuron for post hoc reconstruction of dendritic and axonal architecture.

Imaging the dynamic behavior of organelles and other subcellular structures in vivo can shed light on their function in physiological and disease conditions. Here, we present methods for genetically tagging two organelles, centrosomes and mitochondria, and imaging their dynamics in living zebrafish embryos using wide-field and confocal microscopy.
FAQs
Ion channels support membrane signaling by regulating how electrical impulses arise and propagate along a neuron. Their molecular activity links changes at the cell membrane with communication through the axon and toward synapses. Examining these components therefore adds functional information that cannot be obtained from cellular shape alone, helping researchers connect neuronal structure with signal transmission.
The cytoskeleton provides internal support for neuronal shape, cellular transport, and axonal integrity. These functions are especially important in the axon, where maintaining structural continuity supports the movement of cellular materials and the transmission of information. Studying cytoskeletal organization can therefore clarify how structural disruption contributes to impaired neuronal function.
Axonal integrity helps preserve the pathway through which electrical impulses reach synapses. When injury or disease disrupts this structure, impulse conduction and subsequent neurotransmitter-based communication may be affected, disturbing nervous system function. This relationship makes axonal structure a relevant focus when investigating neurological injury, neurodegenerative disease, tumors, and related disorders.
The soma, dendrites, and axon support different functional demands within the same nerve cell. The soma maintains cellular functions, dendrites are positioned to receive signals, and the axon carries impulses toward synapses. Comparing these regions helps researchers relate local structural organization to the broader sequence of neural communication without treating the neuron as a uniform compartment.
Structural analysis can reveal how the organization of nerve cells changes in injury, neurodegenerative disease, tumors, or developmental disorders. Linking observed structural changes with disrupted nervous system function provides a basis for interpreting disease-related abnormalities. In medicine, this information supports investigation of how cellular damage may relate to neurological signs and impaired communication.
Understanding which cellular components support membrane signaling, transport, and axonal integrity helps researchers study how nervous system damage develops and how it might be addressed. Structural analysis can guide therapeutic development by identifying the organization and components affected by disease or injury. It also provides a framework for evaluating research aimed at neural repair.
