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

Frontiers 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

Acta 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

Broadening horizons: Pathogenesis and therapeutics of renal ciliopathies

Journal of Cell Communication and Signaling, Volume 20, Issue 3, September 2026.
This review elucidates the molecular mechanisms and aberrant signaling pathways in renal ciliopathies, links genetic heterogeneity to clinical phenotypes, and lays a theoretical basis for prenatal diagnosis and novel therapies. Abstract Renal ciliopathies encompass a spectrum of genetic disorders arising from structural or functional impairments of ...

Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]

, 1986
1. Horseradish peroxidase was applied by iontophoretic injections to physiologically identified regions of the laryngeal motor nucleus, the nucleus ambiguus in the CF/FM batRhinolophus rouxi. 2.

Neuroinflammatory and Motor Alterations in LRRK2*G2019S Transgenic Mice Without Enhanced Vulnerability to Aging or Chronic MPTP‐Induced Nigrostriatal Neurodegeneration

Journal of Neurochemistry, Volume 170, Issue 9, September 2026.
LRRK2 G2019S mutation is the most common genetic cause of Parkinson's disease but its contribution to nigrostriatal neurodegeneration, particularly in response to mitochondrial dysfunction, remains unclear. hLRRK2*G2019S transgenic mice exhibited early microglial activation and motor alterations, but not increased dopaminergic nigrostriatal ...

Acetylcholine release from the midbrain interpeduncular nucleus during anesthesia

, 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.

Evolution of the nucleus [PDF]

, 2014
The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells.

The role of the habenula in drug addiction

Frontiers 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.

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.).

Hippocampal long‐range GABAergic neurons target hippocampal‐projecting cells of the supramammillary area

The Journal of Physiology, Volume 604, Issue 18, Page 7924-7956, 15 September 2026.
Abstract figure legend The hippocampus contains a diversity of inhibitory neurons, including somatostatin‐expressing (SST+) and neuronal nitric oxide synthase‐expressing (NOS+) projection neurons that target extrahippocampal brain regions, including the hypothalamic supramammillary area (SuM).
