The provided code snippet is part of a computational neuroscience model, likely implemented using the NEURON simulation environment, given the presence of nrngui.hoc
. It seeks to simulate and study certain aspects of neuronal behavior, more specifically, the dynamics of calcium (Ca(^{2+})) spikes in a neuron that has been described in the morphology_mechanisms_CaSpikes_SP.hoc
file. Here's a breakdown of the biological basis:
Calcium Spikes:
Neuron Morphology and Mechanisms:
morphology_mechanisms_CaSpikes_SP.hoc
file likely defines the morphology and the ionic channels responsible for generating calcium spikes. Various ion channels, including voltage-gated calcium channels, are integral to these processes.Temperature Setting:
