Doxapram stimulates respiratory activity through distinct activation of neurons in the nucleus hypoglossus and the pre-Botzinger complex
Data from: Long-term adult human brain slice cultures as a model system to study human CNS circuitry and disease
Most of our knowledge on human CNS circuitry and related disorders originates from model organisms. How well such data translate to the human CNS remains largely to be determined. Human brain slice cultures derived from neurosurgical resections may offer novel avenues to approach this translational gap. We now demonstrate robust preservation of the complex neuronal cytoarchitecture and electrophysiological properties of human pyramidal neurons in long-term brain slice cultures. Further experiments delineate the optimal conditions for efficient viral transduction of cultures, enabling "high throughput" fluorescence mediated 3D reconstruction of genetically targeted neurons at comparable quality to state-of-the-art biocytin fillings, and demonstrate feasibility of long term live cell imaging of human cells in vitro. This model system has implications toward a broad spectrum of translational studies, regarding the validation of data obtained in non-human model systems, for therapeutic screening and genetic dissection of human CNS circuitry
Reconstructions of GFP labeled and Biocytin filled neurons and spine details of the analyzed cells
The data is organized as follows:
1) reconstruction: this folder contains two overview gallery pictures and subfolders for each GFP labeled and each Biocytin filled neurons with the original image file and the reconstruction image + a SWC file that can be used to produce a 3D image of the cells
2) spines: This folder contains two exel sheets with the values for spine length, spine density and spine head diameter of the analyzed cells
3) summary files: This exel sheets contain overview information about the reconstructed neurons (apical, basal and total dendrite length
