The provided model code is a representation of the mitral cell, a key neuronal type in the olfactory bulb. Mitral cells receive input from the olfactory bulb's glomeruli and relay information about odors to various brain regions, such as the olfactory cortex. This neuron is critical in the early processing stages of olfactory information. Key aspects of the biological model include:
Ion Channels:
Passive Properties:

and related commands, the code specifies a 3D geometric structure for the dendrites and other parts, facilitating realistic spatial representation of the cell morphology. This structure is crucial for accurate simulation of the spatial spread of excitatory and inhibitory inputs and action potentials.The model is designed to encapsulate key biological features of mitral cells, allowing for detailed exploration of their electrophysiological properties and how they process and transmit olfactory information. By incorporating realistic ion channel distributions, dendritic morphology, and synaptic inputs, the model reflects the complex integration and processing that occurs in the olfactory bulb's mitral cells.
