}Mitochondria play a central role in the survival and death of neurons. The detailed bioenergetic mechanisms by which isolated mitochondria generate ATP, sequester Ca(2+), generate reactive oxygen species, and undergo Ca(2+)-dependent permeabilization of their inner membrane are currently being applied to the function of mitochondria in situ within neurons under physiological and pathophysiological conditions. Here we review the functional bioenergetics of isolated mitochondria, with emphasis on…

This hypothesis that enhanced reactive oxygen species are a consequence rather than a cause of failed cytoplasmic calcium homeostasis, but that prior oxidative damage facilitates DCD by damaging mitochondrial ATP generation is critically re‐examined.

The aim is to illustrate that the structure of the mitochondrial compartment is highly dynamic in neurons, there is a fine-tuned coupling between neuronal activity and mitochondrial function, and mitochondria are of central importance for the complex behavior of neurons.

The conventional view that mitochondrial calcium loading results in increased oxidative stress that damages the mitochondrion and ultimately the cell is revised and may lead to a reevaluation of the potential for mild uncoupling to provide a neuroprotective role in aging‐related neurodegenerative disorders.
A Computational Model of Mitochondria Motility in Axons

A novel computational model of mitochondria motility that focuses on their movements along the axon is introduced and the main parameters of the model are described to investigate how some of these parameters affect the ability of mitochondia to position themselves in regions of high energy demand.

The injection into cells of a key mitochondrial protein, cytochrome c, activates apoptosis, and it is shown that mitochondrial constituents leak out through these permeability transition channels, and activate the apoptotic machinery in the cytosol.
