neurogenesis occurs throughout life in several regions of the brain. in this lecture, a new sight for the role of the dentate gyrus and adult hippocampal neurogenesis in anxiety disorders will be discussed. the region that has obtained the most attention for its involvement in the neurogenesis of affective and anxiety disorders are the hippocampal and dentate gyrus. evidence strongly suggests t...

The co-existence of intellectual disability (ID) and psychiatric disorders is fairly common throughout the lifespan, but there is only limited research on children, adolescents, and young adults with ID and co-occurring, severe psychiatric disorders. Children and adolescents with ID or very low Full Scale IQs are often excluded from studies of psychopathology, including many that investigate Sc...

introduction: previous studies have demonstrated that the &beta-adrenergic; receptor antagonist propranolol impairs fear memory reconsolidation in experimental animals. there are experimental parameters such as the age and the strength of memory that can interact with pharmacological manipulations of memory reconsolidation. in this study, we investigated the ability of the age and the strength ...

Major depressive episode (MDE) is one of the most common psychiatric diagnoses and it has long-term mental and physiological consequences. The status of cognitive functions is of specific importance in case of affective disorders, due to their influence not only on patients' behaviour, but to a certain extent also on the success of psychotherapy.

INTRODUCTION Currently, there is no consensus on the delay necessary to a complete recovery after a transient global amnesia (TGA). However, it seems that slight episodic memory disorders extend beyond 24h. Although this impairment is probably a consequence of the TGA attack, other factors such as patients' emotional state can intervene in the slow recovery process. METHODS In a first experim...

the serotonin (5-ht) receptors are a group of g protein-coupled receptors (gpcrs) and ligand-gated ion channels that found in the central and peripheral nervous systems. 5ht receptor can substantially influence brain functions such as learning and memory, perception of the environment, mood states, and responses to alcohol and other drugs of abuse. lysergic acid diethylamide (lsd) as a 5ht rece...

introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...

chronic  granulomatous  disease (cgd)  is a rare primary immunodeficiency disorder characterized by a greatly increased susceptibility to severe fungal and bacterial infections caused  by  defects  in  nadph   oxidase  of  phagocytic  cells. we  aimed  to  investigate immunophenotype alterations of naïve and memory b cells and b1a cells in peripheral whole blood from iranian patients with cgd. ...
