The Visually Related Posterior Pretectal Nucleus in the Non-Percomorph Teleost Osteoglossum bicirrhosum Projects to the Hypothalamus [PDF]
, 1991 This study was done to elucidate the ancestral (plesiomorphic) condition for visual pathways to the hypothalamus in teleost fishes. Three patterns of pretectal organization can be discerned morphologically and histochemically in teleosts. Their taxonomic

The Renal Nerves in Chronic Heart Failure: Afferent and Efferent Mechanisms
Frontiers in Physiology, 2015 The function of the renal nerves has been an area of scientific and medical interest for many years. The recent advent of a minimally invasive catheter-based method of renal denervation has renewed excitement in understanding the afferent and efferent ...

Sex-specific vagal and spinal modulation of breathing with chest compression.
PLoS ONE, 2020 Lung volume is modulated by sensory afferent feedback via vagal and spinal pathways. The purpose of this study was to systematically alter afferent feedback with and without a mechanical challenge (chest compression). We hypothesized that manipulation of

Plasticity in mammalian somatosensory cerebellar maps [PDF]
, 1996 The organization of sensory maps in mammalian brains can change following peripheral injury or experience. Such plasticity has been demonstrated for somatotopic somatosensory maps in various cortical and subcortical areas. In contrast to somatotopic maps,

Visual and Electrosensory Circuits of the Diencephalon in Mormyrids [PDF]
, 1990 Mormyrids are one of two groups of teleost fishes known to have evolved electroreception, and the concomitant neuroanatomical changes have confounded the interpretation of many of their brain areas in a comparative context, e.g., the diencephalon, where ...

The Effect of Sham Feeding on Neurocardiac Regulation in Healthy Human Volunteers
Canadian Journal of Gastroenterology, 2007 BACKGROUND: Distension and electrical stimuli in the esophagus alter heart rate variability (HRV) consistent with activation of vagal afferent and efferent pathways. Sham feeding stimulates gastric acid secretion by means of vagal efferent pathways.

Integration of sensory quanta in cuneate nucleus neurons in vivo.
PLoS ONE, 2013 Discriminative touch relies on afferent information carried to the central nervous system by action potentials (spikes) in ensembles of primary afferents bundled in peripheral nerves. These sensory quanta are first processed by the cuneate nucleus before

Afferent arteriolar response to arachidonic acid: involvement of metabolic pathways
, 1996 Arachidonic acid (AA) metabolites have been implicated in the control of renal hemodynamics, but the nature of the metabolites produced by renal cells when AA is released has remained uncertain.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
