Background In preclinical models, behavioral training early after stroke produces larger gains compared with delayed training. The effects are thought to be mediated by increased and widespread reorganization of synaptic connections in the brain. It is viewed as a period spontaneous biological recovery during which plasticity increased. Objective To look for evidence similar change human brain ...

Theories of human consciousness substantially vary in the proposed spatial extent brain activity associated with conscious perception as well assumed functional alterations within involved regions. Here, we investigate which local and global changes accompany somatosensory following electrical finger nerve stimulation, whether there are whole-brain network by means graph metrics. Thirty-eight h...

Introduction: Neurons in layer II and III of the somatosensory cortex in rats show high frequency (33 ± 13 Hz) of miniature excitatory postsynaptic currents (mEPSCs) that their rates and amplitudes are independent of sodium channels. There are some changes in these currents in neurodegenerative and psychological disorders. Regarding to well known roles of the neuromodulatory brain systems in...

introduction: in this study, the role of adenosine a1 receptors of hippocampal ca1 region neurons onentorhinal cortex kindled seizures was investigated. material and methods: a tripolar(stimulating and recording) electrode was implanted in entorhinalcortex and two guide cannulae were implanted in the ca1 region of the left and right hippocampi of allanimals. a week after surgery, animals were s...

Deciding how to manipulate an object fulfill a goal requires accessing different types of object-related information. How these information are integrated and represented in the brain is still open question. Here, we focus on examining two information–tool-gesture knowledge (i.e., object), tool-gesture production actual manipulation object). We show double dissociation between production: Patie...

brain areas implicated in the stress response include the amygdala, hippocampus and prefrontal cortex. neonatal stimulation of an animal by handling or by enhanced maternal care induces at adult age a decrease of the hypothalamo-pituitary adrenal (hpa) response to stressors, a decrease of anxiety in a novel environment, and neuroanatomical changes. in this present study we demonstrated that mat...

Background: There has been a rise in accidental poisoning cases resulting from the indiscriminate use and exposure to Dichlorvos (DDVP), especially in developing countries, and no antidote with satisfactory efficacy is currently available. Thus, we investigated the AChE reactivation potential of Nigella sativa oil (NSO) following DDVP induced AChE inhibition patterns in the brain and the associ...
