Neuronal morphology is an essential element for brain activity and function. We take advantage of current availability of brain-wide neuron digital reconstructions of the Pyramidal cells from a

We study the hormonal and neuronal mechanisms behind pupal diapause in the butterfly Pieris napi. Principal Investigator: Mikael Carlsson

To quantify this bias we compare the extracted morphology of neurons collected from the same rodent species, experimental condition, gender distribution, age distribution, brain region and putative cell type, but Here we quantify the impact of neuron morphology on AIS plasticity using computational models of simplified and realistic somatodendritic morphologies. In small neurons (e.g., dentate granule neurons), excitability was highest when the AIS was of intermediate length and located adjacent to the soma. Motivation: Tracing of neuron morphology is an essential technique in computational neuroscience. However, despite a number of existing methods, few open-source techniques are completely or sufficiently automated and at the same time are able to generate robust results for real 3D microscopy images. We find this representation to be more convenient than the traditional SWC format of neuron morphology (Cannon et al., 1998) because the latter cannot be used to describe structures containing loops. Because the initial trace lies sufficiently close to the centerline of neurites, this trace can be optimized by monitoring its fitness in response to small changes in the position and caliber of NEURON doesn't use cylinders.

And we have pyramidal neuron, that's a typical neuron in our hippocampus that we mentioned in the last lecture. Neurons are one of the most diverse cellular populations in the human body. They have a wide variety of branching patterns that is characteristic of a particular subset of neurons. The size differences are also very eclectic. Some neurons are long, wide and myelinated (covered in myelin sheath), while others are short, narrow and unmyelinated.

The broad applicability of “digital reconstructions” of neuron morphology across neuroscience subdisciplines has stimulated the rapid development of numerous synergistic tools for data acquisition, anatomical analysis, three-dimensional rendering, electrophysiological simulation, growth models, and data sharing.

Most individuals with classic GBE1 adult polyglucosan body disease (GBE1-APBD) present after age 40 years with unexplained progressive neurogenic bladder, gait difficulties (i.e., spasticity and weakness) from mixed upper and lower motor neuron involvement, sensory loss predominantly in the distal lower extremities, autonomic dysfunction (associated with orthostatic hypotension and

And then from this morphology we can see different types of neuron or different shape of neuron. It can determine the different function of neurons. And we have pyramidal neuron, that's a typical neuron in our hippocampus that we mentioned in the last lecture. Neurons are one of the most diverse cellular populations in the human body.

In this Primer, Parekh and Ascoli discuss reconstruction of neuronal morphology. They cover the processes of labeling, imaging, and tracing of neurons and provide an annotated compilation of currently available resources for digital reconstruction. 2020-05-30 neuron_morphology A package for working with single-neuron morphological reconstruction data, such as those in the Allen Cell Types Database . Provides tools … We recommend installing neuron_morphology into a managed Python environment.
