The 5-HT1A receptor and recognition memory possible modulation of its behavioral effects by the nitrergic system
(2005)Functional activation of the 5-HT1A receptor inhibits cognition, although discrepant findings have also been reported. The present study was designed to investigate the role of the 5-HT1A receptor on recognition memory in ... -
Acute resistance exercise results in catecholaminergic rather than hypothalamic-pituitary-adrenal axis stimulation during exercise in young men
(2010)Exercise is a paradigm of a stress situation. The adaptive response to stressors comprises the activation of the hypothalamic-pituitary-adrenal (HPA) axis and components of the autonomic sympathetic system. An aseptic ... -
Bully/victim problems and their association with psychological constructs in 8-to 12-year-old Greek school children
(2000)The aim of the present study was to replicate some of the already existing findings regarding the assessment of bully/victim problems in a sample of Greek primary school pupils using the Bullying Behaviour Scale and the ... -
Effects of scopolamine and L-NAME on rats' performance in the object location test
(2007)The object location task is a new procedure evaluating spatial memory abilities in the rat. The aim of the present study was to characterize this behavioural paradigm by pharmacologic means. For this purpose, the effects ... -
Effects of the nitric oxide synthase inhibitor L-NAME on different memory components as assessed in the object recognition task in the rat
(2010)Nitric oxide (NO) is sought to be an intracellular messenger in the central nervous system and its implication in learning and memory is well documented. Compounds that inhibit nitric oxide synthase (NOS), the key synthesizing ... -
'Freedom from hunger' and preventing obesity: the animal welfare implications of reducing food quantity or quality
(2009)In animals, including humans, free access to high-quality (generally energy-dense) food can result in obesity, leading to physiological and health problems. Consequently, various captive animals, including laboratory and ... -
The metabotropic glutamate 2/3 receptor antagonist LY341495 differentially affects recognition memory in rats
(2012)Experimental evidence suggests that metabotropic glutamate 2/3 (mGlu2/3) receptor antagonists affect cognitive function, although contradictory findings have been reported. To clarify the role of mGlu2/3 receptor antagonists ... -
The nitric oxide (NO) donor molsidomine antagonizes scopolamine and L-NAME-induced performance deficits in a spatial memory task in the rat
(2009)Nitric oxide (NO) is considered as an intracellular messenger in the brain. Its involvement in learning and memory processes has been proposed. Compounds that inhibit NO synthase (NOS), the key synthesizing enzyme, may ... -
Nitric oxide modulates apomorphine-induced recognition memory deficits in rats
(2012)Nitric oxide (NO) is an important intracellular messenger in the brain. The implication of NO in schizophrenia is well documented although it is not yet clear whether net over or underproduction of NO is typical of this ... -
A novel flexible method to split feeding behaviour into bouts
(2009)Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the ... -
PKC-epsilon activation is required for recognition memory in the rat
(2013)Activation of PKC epsilon, an abundant and developmentally regulated PKC isoform in the brain, has been implicated in memory throughout life and across species. Yet, direct evidence for a mechanistic role for PKC epsilon ... -
Polygyny in the olive fly-effects on male and female fitness
(2015)Polygynous males must balance their limited ejaculate resources between current copulations, with putative future ones. Working on olive flies (Bactrocera oleae), our objectives were to determine (a) how males budget sperm ... -
Relation of anxiety to hostility in the course of inpatient treatment
(2006)The purpose of this study was to examine relationships between anxiety and hostility in hospitalized psychiatric patients, with the passage of time. The used psychometric instruments were the state of anxiety subscale (sA) ... -
Repeated administration of the nitric oxide synthase inhibitor L-NAME differentially affects rats' recognition memory
(2011)Nitric oxide (NO) is sought to be an intracellular messenger in the central nervous system and its implication in learning and memory is well documented. Compounds that inhibit nitric oxide synthase (NOS), the key synthesizing ... -
The role of nitric oxide in the object recognition memory
(2015)The novel object recognition task (NORT) assesses recognition memory in animals. It is a non-rewarded paradigm that it is based on spontaneous exploratory behavior in rodents. This procedure is widely used for testing the ... -
The selective 5-HT6 receptor antagonist Ro 04-6790 attenuates psychotomimetic effects of the NMDA receptor antagonist MK-801
(2008)There are experimental evidences indicating that the non-competitive NMDA receptor antagonist MK-801 impairs cognition and produces a series of schizophrenia-like symptoms in rodents (hypermotility, stereotypies and ataxia). ...
