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 ...

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.

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

Journal of Anatomy, Volume 249, Issue 1, Page 207-221, July 2026.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

Mu Opioid Receptor mRNA and Protein Localization Across the Rat and Mouse Habenula

Journal of Comparative Neurology, Volume 534, Issue 6, June 2026.
Mu opioid receptor (MOR) mRNA was detected with RNAscope in situ hybridization for Oprm1 and protein was detected with immunocytochemistry to map the distributions across the anterior‐posterior extent of the rat and mouse habenula. Expression distribution was also characterized in a transgenic reporter mouse line (Oprm1‐Venus/Venus) as an additional ...

Genetically defined nucleus incertus neurons differ in connectivity and function

eLife
The nucleus incertus (NI), a conserved hindbrain structure implicated in the stress response, arousal, and memory, is a major site for production of the neuropeptide relaxin-3.

Evaluating Anesthetics for Improving Scientific Research and Welfare Using Larval Zebrafish

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Using physiological and behavioral assays, we quantified the effectiveness and appropriateness of six commonly used fish anesthetics on zebrafish embryos. Different anesthetics performed better under different contexts. Figure prepared using BioRender.com.

Interpeduncular heterotopia in Joubert syndrome: a previously undescribed MR finding [PDF]

, 2011
The so-called molar tooth sign is the radiologic hallmark of JSRD. Joubert syndrome is a rare, most often autosomal-recessive disorder with a characteristic malformation of the midhindbrain.

Defining a role for the peduncolopontine tegmental nucleus in striatal outflow [PDF]

, 2012
The pedunculopontine tegmental nucleus (PPTg) lies within the pontomesencephalon and contains cholinergic and non-cholinergic neurones. It has extensive afferent and efferent connections throughout the brain.

Heparan sulfate endosulfatases, Sulf1 and Sulf2, are required for formation of the medial habenula-interpeduncular nucleus circuit

Frontiers in Neuroanatomy
The medial habenula (MHb), a medial subdivision of the habenula located in the dorsal diencephalon, sends axons towards the interpeduncular nucleus (IPN) through the fasciculus retroflexus.

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.
