Heroin sensitization induces circumventricular organ activation in the rat brain

, 2005
Using c-Fos protein immunohistochemistry we previously demonstrated various sites of activation in the rat forebrain according to the animal's drug history. This study originates from a more detailed evaluation ex-post of the same specimens.

Role of circumventricular organs in pro-inflammatory cytokine-induced activation of the hypothalamic-pituitary-adrenal axis

, 2001
1. The past 15 years has seen the emergence of a new field of neuroscience research based primarily on how the immune system and the central nervous system can interact. A notable example of this interaction occurs when peripheral inflammation, infection

Fluorescein-Enhanced Characterization of Additional Anatomical Landmarks in Cerebral Ventricular Endoscopy [PDF]

, 2013
BACKGROUND:: Fluorescein enhancement to detect retinal disorder or differentiate cancer tissue in situ is a well-defined diagnostic procedure. It is a visible marker of where the blood-brain barrier is absent or disrupted.

Fos response of fetal sheep anterior circumventricular organs to osmotic challenge in late gestation

, 1998
We hypothesized that the anterior circumventricular organs (ACVO) and the supraoptic (SON) and hypothalamic paraventricular nuclei (PVN), among other structures that play a role in sensing extracellular body fluid volume and composition in postnatal ...

Discovery of Multiple Venous Portal Systems in the Mammalian Brain

, 2023
There are two distinct communication systems in the brain, term wiring and volume transmission (Agnati et al., 2010). Volume transmission refers to a way of communication lacking any wire-like channel connecting the source of signal and its target.

Pyrogenic and neuroinflammatory properties of zymosan and its potential as an alternative to live yeast in antipyretic drug testing

FACETS, 2019
Zymosan, an immunogenic cell wall extract of Saccharomyces cerevisiae has potential for use as an experimental pyrogen. However, the short-lived sickness responses noted with intraperitoneal and intra-articular administration of zymosan limits ...

Why trypanosomes cause sleeping sickness.

, 2004
African trypanosomiasis or sleeping sickness is hallmarked by sleep and wakefulness disturbances. In contrast to other infections, there is no hypersomnia, but the sleep pattern is fragmented.

Hydration and beyond: neuropeptides as mediators of hydromineral balance, anxiety and stress-responsiveness

Frontiers in Systems Neuroscience, 2015
Challenges to body fluid homeostasis can have a profound impact on hypothalamic regulation of stress responsiveness. Deficiencies in blood volume or sodium concentration leads to the generation of neural and humoral signals relayed through the hindbrain
