Deterioration or loss of synapses can result in changes in mood and cognition, and in alterations of brain functioning, such as those associated with neurological disorders or aging.
To circumvent the difficulty in analyzing CNS synapses, isolated preparations of the nervous system, such as dissociated neuronal cultures, were extensively utilized to identify the nascent synapses formed between CNS neurons.
