the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...

Previously published studies report an improvement in hyperactivity following exposure to vestibular semicircular canal stimulation under eyes-open, lights-on conditions (conditions that provide visual feedback). To separate the effectiveness of vestibular stimulation from that of visual stimulation, 30 primary school children who met the criteria for having attention deficit disorder with hype...

Objectives: Autism is one subsets of pervasive developmental disorders that are characterized by abnormal behaviors and verbal communication. In recent years, the reason for this communication disorder has been developed for determining executive function. The current study investigated the feasibility of audiovisual stimulation intervention focused on enhancing executive function in children w...

modulation of dorsolateral prefrontal cortex (DLPFC) activity using non-invasive brain stimulation, such as transcranial direct current stimulation (tDCS), enhanced the prospects of substance use disorders rehabilitation. Methods: we carried out a randomized sham-controlled clinical trial to assess the effect of repeated tDCS at DLPFC on drug craving in 30 abstinent male methamphetamine users. ...

Occipital stroke often leads to visual field loss, for which no effective treatment exists. Little is known about the potential of non-invasive electric current stimulation to ameliorate visual functions in patients suffering from unilateral occipital stroke. One reason is the traditional thinking that visual field loss after brain lesions is permanent. Since evidence is available documenting v...

Small, achromatic circular sinusoids were presented in the central and peripheral visual fields to investigate dorsal visual stream activation. It was hypothesized that peripheral stimulation would lead to faster onset latencies, as well as preferentially activate dorsal stream visual areas relative to central field stimulation. Although both central and peripheral stimulation activated similar...

In visual suppression paradigms, transcranial magnetic stimulation (TMS) applied approximately 90 ms after visual stimulus presentation over occipital visual areas can robustly interfere with visual perception, thereby most likely affecting feedback activity from higher areas (Amassian VE, Cracco RQ, Maccabee PJ, Cracco JB, Rudell A, Eberle L. 1989. Suppression of visual perception by magnetic ...

In schizophrenia, aberrant brain activity has been reported both during stimulus processing and at rest. Evoked response amplitude is a function of both the number and synchronization of neurons firing in relation to a stimulus. It is at present unclear whether schizophrenia patients have normal synchronization of neural activity in relation to stimulus processing, and whether the amount and ti...

Background & Aims: Change in visual experience impairs circadian rhythms. In this study, The effects of visual deprivation during critical period of brain development and melatonin intake on synaptic plasticity of hippocampal CA1 neurons were evaluated. Methods: This experimental study was done on male rats kept in standard 12 hour light/dark condition (L...
