How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

In this Perspective review, we highlight some of the less explored aspects of lateral habenula (LHb) function in contextual memory, sleep, and behavioral flexibility. We provide evidence that LHb is well-situated to integrate different internal state and multimodal sensory information from memory-, stress-, motivational-, and reward-related circuit...

Increasing evidence points to the engagement of the lateral habenula (LHb) in the selection of appropriate behavioral responses in aversive situations. However, very few data have been gathered with respect to its role in fear memory formation, especially in learning paradigms in which brain areas involved in cognitive processes like the hippocampu...
Chapter
The habenula is a diencephalic brain region that has attracted growing interest over the past decade because of its role in reward‐related behaviours and potential involvement in neuropsychiatric disorders in which reward processes are perturbed. The habenula exerts remarkable control over major dopaminergic and serotonergic neurotransmitter system...
Article
The dorsal hypothalamic area regulates increases in body temperature in response to stress, but precise mechanisms are unclear. A new study suggests that glutamatergic neurons in this brain area regulate this action and, surprisingly, may also be involved in blushing.
Article
Addiction is now recognized as a neurobiological and cognitive brain disorder and is generally viewed as a switch from recreational or voluntary to compulsive substance use despite aversive consequences. The habenula, composed of medial (MHb) and lateral (LHb) domains, has been implicated in regulating behavioral flexibility and anxiety-related beh...

Pain associates both sensory and emotional aversive components, and often leads to anxiety and depression when it becomes chronic. Here, we characterized, in a mouse model, the long-term development of these sensory and aversive components as well as anxiodepressive-like consequences of neuropathic pain and determined their electrophysiological imp...
Article
The lateral habenula (LHb) is involved in emotional and cognitive behaviors. Recently, we have shown in rats that blockade of excitatory inputs to the LHb not only induced deficits of memory retrieval in the water maze, but also altered swim strategies (i.e., induced excessive thigmotaxis). The latter observation, although consistent with the occur...
Article
Our memory abilities, whether they involve short-term working memory or long-term episodic or procedural memories, are essential for our well-being, our capacity to adapt to constraints of our environment and survival. Therefore, several key brain regions and neurotransmitter systems are engaged in the processing of sensory information to either ma...
Thesis
Ce travail de thèse avait pour objectif d’étudier le rôle de l’habénula latérale (HbL) dans les processus mnésiques chez le Rat en utilisant une approche par inactivation réversible grâce à l’administration de muscimol ou de CNQX. Nous avons ainsi montré l’implication de l’HbL dans : i) les processus d’encodage et de rappel d’une mémoire spatiale e...
Article
Working memory is a cognitive ability allowing the temporary storage of information to solve problems or adjust behavior. While working memory is known to mainly depend on the medial prefrontal cortex (mPFC), very few is known about how cortical information are relayed subcortically. By its connectivity, the lateral habenula (lHb) might act as a su...
Article
Full-text available
The Lateral habenula (LHb) is viewed as a relay between the limbic system, the basal ganglia (BG), and monoaminergic neurons of the midbrain. If a prominent role has been evidenced in BG-mediated functions such as value-based decision making, very little is known about the involvement of the LHb in limbic functions such as memory processing. In the...
