Ghrelin, a brain-gut peptide discovered from the stomach, stimulates growth hormone release, food intake, adiposity, and weight gain. Circulating ghrelin levels are modulated under conditions of positive and negative energy balance, however its effect on macronutrient selection is not known. The...
Previous work from our laboratory has shown that naïve Wistar Audiogenic Rats (WARs), a genetic model of reflex epilepsy in which seizures are induced by high-intensity sound stimulation (120 dB SPL), are seizure-prone to a variety of pro-convulsive stimuli (e.g., transauricular electroshock,...
We investigated whether the retrosplenial and the posterior cingulate cortex (RS-PCC) is functionally impaired in schizophrenia patients. Therefore, we measured functional magnetic resonance imaging (fMRI) signal changes associated with a synonym-judgment task known to activate, among other...
The present study was aimed at investigating whether two-kidney, one clip (2K1C) hypertension is associated with an enhanced central adrenergic activity. Rats were made 2K1C hypertensive, and the expression of Fos-like immunoreactivity (FLI) and phenylethanalamine N -methyltransferase...
The goals of this study were to examine the visual information influence on body sway as a function of self- and object-motion perception and visual information quality. Participants that were aware (object-motion) and unaware (self-motion) of the movement of a moving room were asked to stand...
The present study evaluated the relationship between asymmetry of the prefrontal cortex activity and the automatic nervous system (ANS) response during a mental arithmetic (MA) task. Employing near infrared spectroscopy, we compared cerebral blood oxygenation changes in the right and left...
Dysregulations of calcium (Ca) homeostasis may be involved in the pathophysiology of bipolar disorder. Enhanced Ca response to various agonists in peripheral blood cells is one of a few confirmed biological markers for bipolar disorder. Recently, a polymorphism of XBP1, a pivotal gene in the...
Following recurrent noxious stimulation, both functional modification and structural reorganization such as activation of the arachidonate cascade or axon sprouting occur in the central nervous system (CNS). It has been recently proposed that these alterations observed during chronic pain state...
