Neuron Assessment

Neuron assessment is the systematic evaluation of neuronal structure, function, connectivity, and health in cells, tissues, or model organisms. It combines methods such as microscopy to examine morphology, immunostaining to identify cell types and proteins, and electrophysiology to measure membrane potentials and action potentials. These approaches reveal how neurons develop, communicate through synapses, respond to stimuli, or change during disease and injury. In biology, neuron assessment supports studies of neural circuits, neurodevelopment, neurotoxicity, and treatments, while standardized measurements improve comparisons across experiments and help link cellular changes to behavior and neurological function.

A protocol to generate a co-culture system consisting of neurons derived from induced pluripotent stem cells (iPSCs), primary cortical neurons and astrocytes is described. This co-culture system allows detection of the formation of synaptic contacts and circuits between new, iPSC-derived neurons and pre-existing cortical neurons expressing channelrhodopsin-2.

Compound muscle action potential recording quantitatively assesses functional diaphragm innervation by phrenic motor neurons. Whole-mount diaphragm immunohistochemistry assesses morphological innervation at individual neuromuscular junctions. The goal of this protocol is to demonstrate how these two powerful methodologies can be used in various rodent models of spinal cord disease.
