Mapping neuronal inputs to Kiss1 neurons in the arcuate nucleus of the mouse.

open access: yesPLoS ONE, 2019
The normal function of the mammalian reproductive axis is strongly influenced by physiological, metabolic and environmental factors. Kisspeptin neuropeptides, encoded by the Kiss1 gene, are potent regulators of the mammalian reproductive axis by ...

Increased metabolic activity in the septum and habenula during stress is linked to subsequent expression of learned helplessness behavior

open access: yesFrontiers in Human Neuroscience, 2014
Uncontrollable stress can have a profound effect on an organism’s ability to respond effectively to future stressful situations. Behavior subsequent to uncontrollable stress can vary greatly between individuals, falling on a spectrum between healthy ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

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

open access: yesJournal 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.

Down-regulation of habenular calcium-dependent secretion activator 2 induces despair-like behavior

open access: yesScientific Reports, 2021
Calcium-dependent secretion activator 2 (CAPS2) regulates the trafficking and exocytosis of neuropeptide-containing dense-core vesicles (DCVs). CAPS2 is prominently expressed in the medial habenula (MHb), which is related to depressive behavior; however,

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

open access: yesJournal 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 ...

The role of the habenula in drug addiction

open access: yesFrontiers in Human Neuroscience, 2014
Interest in the habenula has greatly increased in recent years. The habenula is a small brain structure located posterior to the thalamus and adjacent to the third ventricle.

Evaluating Anesthetics for Improving Scientific Research and Welfare Using Larval Zebrafish

open access: yesComprehensive 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.

Acetylcholine release from the midbrain interpeduncular nucleus during anesthesia

open access: yes, 1991
AN exceptional local rise in metabolism during general anesthesia has been noted previously in the ventral midbrainʼs highly cholinoceptive interpeduncular nucleus (IPN). We report here a functional correlate.

Organization of multisynaptic inputs to the dorsal and ventral dentate gyrus: retrograde trans-synaptic tracing with rabies virus vector in the rat.

open access: yesPLoS ONE, 2013
Behavioral, anatomical, and gene expression studies have shown functional dissociations between the dorsal and ventral hippocampus with regard to their involvement in spatial cognition, emotion, and stress. In this study we examined the difference of the
