Introduction: Filtering can greatly affect the quality of clinical images. Determining the best filter and the proper degree of smoothing can help to ensure the most accurate diagnosis. Methods: Forty five patient’s data aquired during brain phantom SPECT studies were reconstructed using filtered back-projection technique. The ramp, Shepp-Logan, Cosine, Hamming, Hanning, Butterworth, Metz...

Neuroimaging findings have proposed that some brain regions including the precuneus, posterior cingulate, and medial prefrontal cortex play an essential role of a structural core in the brain. Network organization endures rapid alterations in development with changes in axonal synaptic connectivity, white matter volume, and the thickness of corresponding cortical regions. Structural maturation ...

the purpose of this research was to determine the effect of two kinds of diet (zinc deficiency and iron deficiency) on some anthropometrical indexes (body weight and crown-rump length), brain growth and motor function in young rats. adult male and female albino wistar rats were obtained from the breeding colony of pasteur institute, iran. the female albino rats were mated with normal male rats....

Purpose: Neuroscience studies suggest that Chronic Low Back Pain (CLBP) is associated with central sensitization, and maladaptive reorganization of the brain; this introduced a new target for LBP treatment. Studies revealed that cortical and peripheral electrical stimulation can be beneficial in regulating brain neuronal activity. However, there is a scarcity of evidence to support the effects ...

brain stimulation techniques are important in both basic and clinical studies. majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. low intensity focused ultrasound (lifu) seems to be a proper candidate for dealing with such deficiencies. this review recapitulates studies which explored the effects of lifu on brain structures and its func...
