Lack of effect of habenula lesion on heroin self-administration in rats.

15 Jun 2009 We examined the effects of bilateral electric lesion of the habenula (Hb) on the acquisition and maintenance of heroin self-administration. The rats were trained to self-administer heroin (0.05 mg/kg/infusion) under FR1 schedule in daily 4h ... Read more...

Mechanisms of directional asymmetry in the zebrafish epithalamus.

30 May 2009 The epithalamus of zebrafish presents the best-studied case of directional asymmetry in the vertebrate brain. Epithalamic asymmetries are coupled to visceral asymmetry and include left-sided migration of a single midline structure (the parapineal ... Read more...

Trafficking of neurokinin-1 receptors in serotonin neurons is controlled by substance P within the rat dorsal raphe nucleus.

24 May 2009 Substance P (SP) modulates serotonin neurotransmission via neurokinin-1 receptors (NK1rs), and exerts regulatory effects on mood through habenular afferents to the dorsal raphe nucleus (DRN). We have previously demonstrated that, in the caudal DRN ... Read more...

Technical information about 'Habenula'

Definition: A small protuberance at the dorsal, posterior corner of the wall of the third ventricle, adjacent to the dorsal thalamus and pineal body. It contains the habenular nuclei and is a major part of the epithalamus. (From Lockard, Desk Reference for Neuroscience, 2nd ed, p121)
