Neuronal Network Dysfunction in Neurological and Psychiatric Disorders

Experimental Neurology

Growing evidence has indicated the existence of deleterious networks in the brain of neurological and psychiatric disorders, including Alzheimer disease, Parkinson’s disease, Huntington’s chorea, depression or schizophrenia. The deleterious neural networks are formed on the basis of intimate interactions among key pathogenic factors. These deleterious networks could be the common pathway of these brain disorders, triggering of which by aging, certain genetic and environmental factors leading to a cascade of pathological alterations of the illnesses. Understanding the mechanisms that modulate connectivity and plasticity of neural circuitry is crucial to develop new network-based therapeutical strategies.
