The Role of the Lateral Habenula in Punishment

Abstract: The lateral habenula (LHb) is a small epithalamic structure that projects via the fasciculus retroflexus to the midbrain. The LHb is known to modulate midbrain dopamine (DA) neurons, including inhibition of ventral tegmental area (VTA) neurons via glutamatergic excitation of the GABAergic rostromedial tegmental nucleus (RMTg). A variety of lines of evidence show activity in LHb and the LHb-RMTg pathway is correlated with, and is sufficient to support, punishment learning. However, it is not immediately clear w… Show more

“…In the second part of our study we showed a significant change in the locomotor activity in rats in the hole-board after LHb lesion when compared to sham-lesioned rats, as previously observed in many other studies (Nielson and McIver, 1966 ; Lecourtier et al, 2008 ; Gifuni et al, 2012 ; Wang et al, 2013 ; Jean-Richard Dit Bressel and McNally, 2014 ) validating the manipulation within the current study. This locomotor effect is likely due to the strong inhibitory control over midbrain DA neurons exerted by the LHb (Matsumoto and Hikosaka, 2007 ).…”

“…Optogenetic stimulation of the LHb → RMTg pathway negatively reinforces nose-poking and suppresses acquisition of a reinforced response [ 152 ]. However, these studies did not isolate punishment and a variety of approaches to preventing LHb activity do not affect punishment suppression in rats [ 165 ]. That said, the LHb appears to play important roles in active avoidance [ 159 ] and risky decision-making [ 166 ].…”

“…The role of the lateral division of the habenular complex (LHb) in regulating dopaminergic activity in the VTA via the rostromedial tegmental nucleus has been established, and represents an important mechanism by which aversion and addiction are modulated (Barrot et al 2012, Sanchez-Catalan et al 2016, Jean-Richard Dit Bressel & McNally 2014, Quina et al 2015). Both the LHb and MHb send dense efferent projections through the fasciculus retroflexus, and anatomical studies suggest that projections emerging from the MHb course through the core and those from the LHb through the sheath of this dense fiber bundle (Bianco & Wilson 2009).…”
