![]() You will now be presented with a traced neuron with dendrite diameters comparable to those seen in the original fluorescence data. The overview includes lengths, areas, volumes. Depending upon the size of the image this step may also take several minutes of processing time. The neuron summary provides an overview of the selected neuron components: axons, dendrites, and cell body. This protocol will facilitate efforts toward understanding the connectivity patterns and neuronal morphologies that characterize healthy brains, and the changes in these characteristics that arise in diseased brain states. Choose a level that you believe best represents the actual structure of the neuron and move on to the next step. Classifying neurons according to differences in. C4 da neuron dendrite defects in Ret ko and mav ko were not enhanced in double knockout larvae. This work presents a relatively rapid method of processing, visualizing, and analyzing thick slices of labeled neural tissue at high-resolution using CLARITY tissue clearing, confocal microscopy, and image analysis. Dendrites are the branched projections of a neuron, and dendritic morphology reflects synaptic organization during the development of the nervous system. Neurons are connected by complex branching processesaxons and dendritesthat process information for organisms to respond to their environment. (BD) Quantitative analysis of C4da neuron (B) dendrite length, (C) number of terminals, and (D) dendrite complexity by Strahler analysis of indicated genotypes. In tandem, advances in image processing software provide methods of quickly analyzing large imaging datasets. Improvements in tissue clearing have allowed for high-resolution imaging of thick brain slices, facilitating morphological reconstruction and analyses of neuronal substructures, such as dendritic arbors and spines. As such, much of what is known about brain function has arisen alongside developments in imaging technologies that allow further insight into how neurons are organized and connected in the brain. Brain activity, the electrochemical signals passed between neurons, is determined by the connectivity patterns of neuronal networks, and from the morphology of processes and substructures within these neurons.
