The neuronal membrane proteasome (NMP) was recently identified in a subset of somatosensory neurons as a key regulator of touch, pain, and itch perception. This article presents a robust workflow for analyzing cell-type-specific NMP expression and function using cell sorting, transcriptome profiling, and culture-based immunofluorescent analyses.

Analyzing the physiological properties of olfactory sensory neurons still faces technical limitations. Here we record them through perforated patch-clamp in an intact preparation of the olfactory epithelium in gene-targeted mice. This technique allows the characterization of membrane properties and responses to specific ligands of neurons expressing defined olfactory receptors.

In utero electroporation is a valuable method for transfecting neuronal progenitor cells in vivo. Depending upon the placement of the electrodes and the developmental timepoint of electroporation, certain subsets of cortical cells can be targeted. Targeted cells can then be analyzed in vivo or in vitro for effects of genetic alteration.
FAQs
Membrane potentials indicate the electrical state of a neuron, while action potentials show how that state changes during signal transmission. Analyzing these measurements helps researchers relate cellular excitability to the timing and propagation of neural signals. This connection is important for explaining how individual neurons contribute to communication within larger neural circuits.
Calcium dynamics provide a measurable link between neuronal electrical activity and downstream cellular events. Changes in calcium can be examined alongside membrane potentials, action potentials, and neurotransmitter release to determine how signals are converted into cellular responses. These measurements help clarify communication between neurons and can reveal altered activity associated with neurological disease mechanisms.
Defined stimuli provide controlled conditions for examining how neurons respond to specific inputs. Researchers can compare electrical activity, calcium changes, or broader network responses across those conditions, making stimulus-related effects easier to identify. This approach supports investigation of sensory processing and helps connect cellular responses with circuit activity and, ultimately, behavior.
Patch-clamp electrophysiology measures neuronal electrical properties, whereas imaging can track activity-related signals such as calcium dynamics. Computational analysis adds a way to organize and interpret measurements from individual cells or neural networks. Used together, these approaches provide complementary information about excitability, synaptic transmission, stimulus responses, and patterns of network activity.
Researchers interpret cellular measurements in relation to synaptic transmission, network activity, and behavioral responses. This multilevel approach helps determine whether changes observed in individual neurons correspond to altered circuit function or behavior. It is particularly useful for studying development, learning and memory, and sensory processing, where cellular events must be understood within functioning neural systems.
The resulting measurements can reveal how neural signaling changes during development, learning and memory, sensory processing, or neurological disorders. By comparing electrical, calcium, synaptic, and network responses, investigators can examine disease mechanisms and assess potential therapeutic interventions. The analysis therefore supports both basic neuroscience and studies seeking measurable evidence of treatment-related effects.
