Biological Basis of the Code

The code provided models the dynamics of internal calcium concentration in neurons, specifically capturing how calcium levels change due to calcium currents and a simplified model of calcium buffering and removal through an ATPase pump. Here is a breakdown of key biological aspects relevant to this code:

Calcium Dynamics in Neurons

Calcium ions (Ca²⁺) play a critical role in neurons, acting as a secondary messenger in various cellular processes, including neurotransmitter release, gene expression, and synaptic plasticity. They are involved in processes such as muscle contraction, neurotransmitter release at synapses, and signal transduction pathways. Therefore, precise regulation of intracellular calcium concentration is crucial for normal neuronal functioning.
