Preparing 10X genomics CytAssist FFPE sections
By Julia Julia Leonard onDesigning and properly mounting FFPE sections on large-window CytAssist slides is important for downstream analysis and data quality. This protocol describes the key steps for this preparation.
Immunofluorescence on human brain FFPE sections to identify neuromelanin in A6, A9, and A10
By Julia Julia Leonard onThis is the protocol to scan brain neuromelanin with reduced impact of the chemicals on their original color and intensity. The immunofluorescence staining protocol is designed to identify human A6, A9, and A10 cell clusters and alpha-synuclein pathology.
Acute extracellular multi-unit recordings and optotagging
By Julia Julia Leonard onThis protocol details acute extracellular multi-unit recordings and optotagging in mice.
Neuromelanin quantification in stained brain slices of the Locus coeruleus
By Julia Julia Leonard onThis protocol describes an automatizable pipeline for cell counting based on fluorescent stainings with the help of CellPose. Additionally, it describes the entire generation process of plots that show the intensity of neuromelanin per cell based on bright-field images.
Juxtacellular Recordings in Ventral tegmental area and Locus coeruleus
By Julia Julia Leonard onThis protocol describes juxtacellular recordings in the VTA and LC of adult mice, involving anesthesia, precise brain targeting, and neuron labeling. Using specialized electrodes and a dual-channel amplifier, neuronal activity is recorded and modulated with current injections. Following recordings, brains are perfused, fixed, and sectioned for detailed morphological analysis.
Sucrose preference test
By Julia Julia Leonard onThe sucrose preference test assesses the animal’s interest in a sweet-tasting sucrose solution relative to unsweetened water.

Rotarod test
By Julia Julia Leonard onProtocol to assess motor coordination and balance by using an accelerating rod.
Open field test
By Julia Julia Leonard onThe open field test is a simple test to evaluate general motor and explorative behavior in rodents.
Induction of aggregation in alpha-synuclein-expressing cells by treatment with preformed fibrils (PFFs)
By Julia Julia Leonard onThis protocol details how to efficiently produce alpha-synuclein aggregates in cells by templating the misfolding of intracellular alpha-synuclein through treatment with preformed fibrils of alpha-synuclein (PFFs).
