This study was designed to investigate the additional benefits of a multimodal early onset stimulation (MEOS) paradigm when combined with enriched environment (EE) versus EE only and standard housing (SH) on the recovery after experimental traumatic brain injury (TBI). Male Sprague- Dawley rats were subjected to moderate lateral fluid percussion (LFP) brain injury (n = 40) or sham operation (n ...
Neuregulin-1 (NRG1) has been identified as a candidate susceptibility gene for schizophrenia. In the present study the functional role of the NRG1 gene, as it relates to cognitive and social processes known to be disrupted in schizophrenia, was assessed in mice with heterozygous deletion of transmembrane (TM)-domain NRG1 in comparison with wildtypes (WT). Social affiliative behavior was assesse...
The cause of Alzheimer's disease (AD) remains uncertain. The accumulation of amyloid peptides (Aβ) is the main pathophysiological hallmark of the disease. Spatial deficit is an important initial sign of AD, while other types of memory impairments that appear in later stages. The Barnes maze allows the detection of subtle alterations in spatial search by the analysis of use of different strategi...
Background & Aims: Memory and its role in learning have long been of interest to humans. Therefore, human beings have always sought ways to enhance their memory and reduce its deficit. In the present study, the effect of pumpkin seed extract on memory and learning in adult male rats were studied. Methods: The rats (weighing 180-220 g) were divided into 7 groups (n = 8); control, sham (control a...
Introduction: The present study investigated the role of the Basolateral Amygdala (BLA) N-methyl-D-aspartate (NMDA) receptors in stress-induced spatial memory disturbance among the male Wistar rats. Methods: The male Wistar rats (Average weight =200 g) were cannulated bilaterally in the BLA, and entered the study (n=6-8) after one week. They received seven electro–foot-shock stress sessions o...
Background: Human tauopathy brain injections into the mouse induce development of tau aggregates, which spread to functionally connected regions; however, features this neurotoxicity remain unclear. One reason may be short observational periods because previous studies mostly used mutated-tau transgenic mice and needed complete study before these developed neurofibrillary tangles. Objective: To...
