About this Research Topic
The habenula is a small epithalamic structure that is critically involved in the control of major neurotransmitters, such as the cholinergic and monoaminergic (i.e. dopamine, serotonin, noradrenaline/norepinephrine) systems. The role of the habenula in depression and addiction is being investigated intensively. However, the habenula is involved in a wide range of behaviors (e.g. social behavior, circadian rhythms, eating behavior, reward processing, prediction of behavioral output, and subsequent correction) implicated in the neurobiology of a number of psychiatric disorders and neuropsychiatric symptoms. Recent findings confirmed the importance of the habenula in schizophrenia, bipolar disorder, autism, and eating disorders and implicated the habenula in neuropsychiatric symptoms such as sleep disturbances, cognitive flexibility, and agitation/aggressive behavior. Thus, this timely special issue will provide the space and opportunity for an up to date discussion of the important and broad role of the habenula in the various neuropsychiatric disorders and symptoms.
This Research Topic aims to broaden the understanding of the role of the habenula in the numerous psychiatric disorders themselves and in the neuropsychiatric symptoms (e.g. agitation, anxiety, apathy, cognitive inflexibility, hallucinations, depression, disinhibition, eating disturbances, euphoria, sleep disturbances) frequently encountered in the context of other disorders. Combining the expertise of both clinical as well as pre-clinical researchers will deepen our understanding of the importance of the habenula and open new exciting avenues for potential clinical intervention.
This Research Topic deals with research related to all the various neuropsychiatric symptoms and the key role of the habenula in their neurobiological underpinnings and all manuscripts (review and research) that investigate/elucidate the role of the habenula in neuropsychiatric symptoms are welcome. Some suggested topics include:
• Neuroimaging findings that link the habenula to neuropsychiatric symptoms, using:
• Resting-state connectivity
• Structural connectivity
• MRI volume estimation
• The microstructure of the habenula
• Therapeutic interventions that target the habenula
• Studies that elucidate the role of the habenula in neuropsychiatric symptoms
• Investigations of the anatomy of the habenula and its connections
• Manipulation of habenula activity/function, using:
• Pharmacological approaches
• Circuit Manipulation of afferent and efferent connections
Keywords: Psychiatric disorder, Reward & motivation, Monoaminergic system, Neuroimaging, Neuromodulation
