Among the passerine birds, species that store food have an enlarged hippocampal region (dorso-medial cortex), relative to brain and body size, when compared with the non-storers. The volume of one of the major afferent-efferent pathways (the septo-hippocampal pathway) is also greater in food storing species. This specialization of brain structure is discussed in relation to behavioural studies ...
BACKGROUND The authors have previously described an association between cytomegalovirus (CMV) infection and intrahepatic and extrahepatic forms of neonatal cholestasis. Pediatric use of the antiviral drug ganciclovir to treat patients with CMV infection has increased. In this study, infants with CMV infection and cholestasis were treated with ganciclovir. METHODS Six infants with cholestasis ...
Exploratory drive is one of the most fundamental emotions, of all organisms, that are evoked by novelty stimulation. Exploratory behavior plays a fundamental role in motivation, learning, and well-being of organisms. Diverse exploratory behaviors have been described, although their heterogeneity is not certain because of the lack of solid experimental evidence for their distinction. Here we pre...
Several findings obtained in recent years suggest that NGF, aside from its well-established function as a neurotrophic factor for peripheral sympathetic and sensory neurons, also has trophic influence on the cholinergic neurons of the basal forebrain. The present study assessed whether NGF was able to affect survival of central cholinergic neurons after axonal transections in adult rats. The se...
In rats, the septo-hippocampal system is important for memory encoding. Previous reports indicate that muscimol, a specific GABAergic agonist induces learning and memory deficits when infused into the medial septal area. The basolateral nucleus of the amygdala (BLA) modulates memory encoding in other brain areas, including the hippocampus. To explore the interactions between the septo-hippocamp...
The spirit of systems pharmacology was adopted to study the possible mechanisms of anxiolytic drugs on hippocampal electric patterns. The frequency of the hippocampal theta rhythm increases linearly with the intensity of electrical stimulation to the brainstem. The reduction of mean theta frequency in this paradigm predicts the clinical efficacy of anxiolytic drugs. The purpose of this study wa...
