Capitalizing on advances in machine learning and a large sample imaged with 27 min of high-quality functional MRI (fMRI) data (n = 693, ages 8–23 years), we delineate how functional topography evolves during youth. The aim of our study was, therefore, to compare the day-specific association of neuron-specific enolase (NSE) with outcomes in out-of-hospital cardiac arrest (OHCA) survivors treated with hypothermia. Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters). Synonym: Any of a group of neurons that become active both when an animal moves in a certain way and when the animal observes others performing the same action. Neurons come in a variety of sizes and shapes. GABA acts on several different classes of receptors to exert inhibitory effects. The soma (tree trunk) is where the nucleus lies, where the neuron’s DNA is housed, and where proteins are made to be transported throughout the axon and dendrites. Previous work has proposed that persistent activity enables the hippocampus to connect representations of events in time, bridging time gaps on the order of tens of seconds. However, each neuron has only one axon (examples: spinal motor neurons, pyramidal neurons, Purkinje cells).
