A conductor hidden in the orchestra? Role of the habenular complex in monoamine transmission and cognition

Lecourtier, Lucas, Kelly, Peter H.·2007·Neuroscience & Biobehavioral Reviews

Abstract

Influences of the habenular complex on electrophysiological and neurochemical aspects of brain functioning are well known. However, its role in cognition has been sparsely investigated until recently. The habenular complex, composed of medial and lateral subdivisions, is a node linking the forebrain with midbrain and hindbrain structures. The lateral habenula is the principal actor in this direct dialogue, while the medial habenula mostly conveys information to the interpeduncular nucleus before this modulates further regions. Here we describe neuroanatomical and physiological aspects of the habenular complex, and its role in cognitive processes, including new behavioral, electrophysiological and imaging findings. Habenular complex lesions result in deficits in learning, memory and attention, some of which decline during repeated testing, while others become worse, consistent with multiple roles in cognition. The habenular complex is particularly responsive to feedback about errors. Electrophysiological studies indicate a role in metaplasticity, the modulation of neuroplasticity. These studies thus reveal important roles of the habenular complex in learning, memory and attention.

  • The MHb projects almost exclusively to the IPN via the fasciculus retroflexus.

    “Unlike LHb, the MHb projects almost exclusively to the interpeduncular nucleus (IPN) via the fasciculus retroflexus (Fr) (Lecourtier and Kelly 2007;Hikosaka 2010).”

  • The LHb projects densely to the RMTg and has a well-established inhibitory effect on midbrain DA neuron firing.

    “In particular, the LHb projects densely to the rostromedial tegmental nucleus (RMTg) (Jhou et al. 2009), and has a well-established inhibitory effect on the firing of midbrain DA neurons (Lecourtier and Kelly 2007;Matsumoto and Hikosaka 2009;Hikosaka 2010;Bromberg-Martin and Hikosaka 2011).”

  • The habenula is a diencephalic structure on the dorsomedial surface of the caudal thalamus, segregated into medial and lateral domains.

    “The habenula is a diencephalic structure located on the dorsomedial surface of the caudal thalamus that is segregated into medial (MHb) and lateral (LHb) domains (Lecourtier and Kelly 2007;Hikosaka 2010).”

  • LHb neurons are excited by omission of anticipated rewards or exposure to aversive stimuli.

    “LHb neurons are excited by omission of anticipated rewards or exposure to aversive stimuli (Lecourtier and Kelly 2007;Matsumoto and Hikosaka 2009;Hikosaka 2010;Bromberg-Martin and Hikosaka 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
