Evolutionary plasticity of habenular asymmetry with a conserved efferent connectivity pattern. [PDF]

PLoS ONE, 2012
The vertebrate habenulae (Hb) is an evolutionary conserved dorsal diencephalic nuclear complex that relays information from limbic and striatal forebrain regions to the ventral midbrain.

Pharmacologic MRI Brain Imaging Studies of Serotonin 5‐HT1 Receptor Agonists in Awake Mice

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Serotonin (5‐hydroxytryptamine, 5‐HT) type‐1 G protein‐coupled receptors are expressed throughout the central nervous system. 5‐HT1AR activation is the putative mechanism of approved drugs for generalized anxiety disorder and major depressive disorder and is being studied in the treatment of autism and neurological disorders.

STZ-induced hyperglycemia differentially influences mitochondrial distribution and morphology in the habenulointerpeduncular circuit

Frontiers in Cellular Neuroscience
IntroductionDiabetes is a metabolic disorder of glucose homeostasis that is a significant risk factor for neurodegenerative diseases, such as Alzheimer’s disease, as well as mood disorders, which often precede neurodegenerative conditions.

Component of nicotine-induced intracellular calcium elevation mediated through α3- and α5-containing nicotinic acetylcholine receptors are regulated by cyclic AMP in SH-SY 5Y cells.

PLoS ONE, 2020
The pathway from the medial habenular nucleus to the interpeduncular nucleus, in which nicotinic acetylcholine receptor (nAChR) including the α3 and α5 subunits (α3 * and α5 * nAChRs) are expressed, is implicated in nicotine dependence.

Chemical transmission in the rat interpeduncular nucleus in vitro. [PDF]

The Journal of Physiology, 1983
We have used a rat brain‐slice preparation to study the effects of some cholinomimetic and amino acid agonists and antagonists on the discharge frequency of neurones in the interpeduncular nucleus (i.p.n.), and on the response of these neurones to electrical stimulation of their main excitatory input, the fasciculus retroflexus of Meynert (f.r.m.).

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, Volume 39, Issue 4, Page 436-460, May 2026.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

Retrograde Demonstration of Hippocampal Afferents From the Interpeduncular and Renuiens Nuclei

, 1979
The origin of hippocampal afferent projections was studied after horseradish peroxidase injections into the hippocampal formation. Labeled cells were found in the dorsal and ventrolateral aspects of the interpeduncular nucleus and in the ipsilateral ...

Alpha‐2‐adrenoreceptor agonists as analgesic drugs in equine medicine

Equine Veterinary Education, Volume 38, Issue 4, Page 220-228, April 2026.
Summary Managing pain in horses is challenging despite the availability of nonsteroidal anti‐inflammatory drugs, local anaesthetics, opioids and α2‐adrenoreceptor agonists. While α2‐agonists are widely used for sedation and restraint, their analgesic properties remain underutilised.

Afferent and efferent connections of the interpeduncular nucleus, with special reference to the circuits linking the habenula, interpeduncular nucleus, and raphe nuclei.

, 2019
A habênula é uma estrutura epitalâmica diferenciada em dois complexos nucleares, a habênula medial (MHb) e a habênula lateral (LHb). Recentemente, a MHb junto com seu alvo principal, o núcleo interpeduncular (IP), foram identificados como estruturas ...

Postnatal interaction of size and shape in the human endocranium and brain structures

Journal of Anatomy, Volume 248, Issue 3, Page 395-411, March 2026.
Ancestral egg‐laying Sceloporus had dorsoventrally tall female pelvises. Two of three live‐bearing clades evolved larger bodies and flatter, wider pelvises, likely reflecting relaxed allometric limits and selection for crypsis or thermoregulation in terrestrial habitats.
