Our work suggests that APP balance is critical for normal neuronal development, connection of synapses, and dendritic spine development, all of which have implications for the extensive synapse loss and cognitive decline seen in Alzheimer's disease," said the study's author, Dr Hyang-Sook Hoe, a research scientist in the department of neuroscience.
What happens is that the brain produces these electrical activities in what is called spatial scales that emanate from a current that is single to the dendritic spine within the natural areas of the brain.
Neuronal cell adhesion molecules "are critical in the development of the nervous system, contributing to axonal guidance, synaptic formation and plasticity, and neuronal-glial interactions," the researchers explained, while the ubiquitin-proteasome system "operates pre- and post-synaptic compartments, regulating synaptic attributes, including transmitter release, synaptic vesicle recycling in pre-synaptic terminals, and dynamic changes in dendritic spines and the post-synaptic density.
