interdendritische

Interdendritische refers to the spaces or regions located between dendrites. Dendrites are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural networks to the cell body, or soma, of the neuron from which the dendrites project. In other contexts, dendrites can refer to crystal structures that grow in a tree-like branching pattern. The interdendritic space, therefore, is the interstitial area surrounding these dendritic structures.

In the context of neuroscience, the interdendritic space is crucial for neuronal communication. It is filled with extracellular fluid and contains neurotransmitters released from presynaptic terminals. The density and composition of the extracellular matrix within this space can influence synaptic transmission and plasticity. Understanding the interdendritic environment is essential for comprehending how neurons integrate signals and form complex neural circuits.

In materials science and metallurgy, interdendritic regions are often areas where impurities or alloying elements segregate during the solidification of molten metals. As a metal solidifies, dendrites form first, and the interdendritic spaces are filled with the remaining liquid phase, which is typically richer in solute elements. This segregation can significantly affect the mechanical properties, corrosion resistance, and overall performance of cast materials. The study of interdendritic segregation is vital for controlling the microstructure and properties of metallic alloys.
