Bipolar disorder (BD) is a severe and common chronic mental illness characterized by recurrent mood swings between depression and mania. The biological basis of the disease is poorly understood, and its treatment is unsatisfactory. Na, K-ATPase is a major plasma membrane transporter and signal transducer.

Our previous studies supported the notion that alterations in Na, K-ATPase activity were involved in the etiology of BD.

However, toxicity and the small therapeutic window of this family of steroids limit their use. Therefore, attempts to synthesize a potent, but less toxic, CS are of major importance.

Treatments, borne of an understanding of the pathoetiologic mechanisms, need to be developed in order to improve outcomes. Dysregulation of cationic homeostasis is the most reproducible aspect of BD pathophysiology.

Its biological basis is unknown, and its treatment is unsatisfactory. The α1, α2, and α3 isoforms of the Na, K-ATPase, an essential membrane transporter, are vital for neuronal and glial function.

In many animals, chemical cues are crucial for directing behaviors, and multiple chemosensory subsystems serve this purpose. The major subsystems in vertebrates are the main olfactory system (MOS) and the vomeronasal system (VNS).

The biological basis of the disease is poorly understood and its treatment is unsatisfactory. Although in past decades the "monoamine hypothesis" has dominated our understanding of both the pathophysiology of depressive disorders and the action of pharmacological treatments, recent studies focus on the involvement of additional neurotransmitters/neuromodulators systems and cellular processes in BD.

New Method: We provide a comprehensive description of a setup allowing controlled stimulus delivery into the vomeronasal organ (VNO) of anesthetized mice. VNO suction is achieved via electrical stimulation of the sympathetic nerve trunk (SNT) using cuff electrodes, followed by flushing of the nasal cavity.
