Background and Objective: In recent years, numerous studies have suggested dysfunction in brain symmetry as the reason behind developmental stuttering. The purpose of this study was to validate the theory of reversed right hemisphere asymmetry in developmental stutters by quantified EEG. Materials and Methods: 13 Subjects with developmental stuttering, 7 to 23 years old were studied using QE...

Purpose: This study sought to determine sex differences in surface anatomical parameters (thickness and surface areas) of human cerebral cortex in different lobes of the left hemisphere in normal right-handed subjects and right-handed subjects suffering from Alzheimer and Parkinson's diseases. Materials and Methods: This cross-sectional descriptive study was performed on 72 normal human brains...

  Background & Aims: Schizophrenia is characterized by a broad range of unusual behaviors that cause profound disruption in the lives of the patients suffering from the condition. individuals with schizophrenia show dysfunction within brain lobes. The aim of this research was to compare brain posterior areas' wave activities in the schizophrenic patient with a healthy group.   Materials & Metho...

Short-term visual retrieving processes were investigated in three groups, of schizophernics (n=10), right hemisphere brain damaged (n=10) and a normal grou (n=10) . All of subjects were men and right handed. The study utilized WAIS (verbal subtests), meaningless Syllabuses, Retrieve and Recall tests and Non-verbal Patternes Retrieve and Recall Tests. Data were analyzed by three factor repeated ...

Purpose: This study is designed to determine the sex differences in brain weight and volume of left hemisphere and its gray and white matters in right-handed normal subjects and the right-handed subjects which were suffered from Alzheimer and Parkinson diseases. Materials and Methods: This study was performed on 72 normal human brains (38 male, 34 female), 11 brains suffered from Alzheimer (4 ...
