introduction: direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. we compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (lfp) and lfpspike signals, respectively. methods: signals recorded from mt area of a macaque’s brain was used in a simulation app...

the brain is a rare site for metastasis in most extracranial pediatric solid tumors, including wilm’s tumor. outcome for these patients are generally dismal. very few cases have been reported to have good survival even after therapy. this paper reports a case of stage iv wilm’s tumor with lung metastases in a patient who developed a solitary brain metastasis five months after completion of chem...

a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

Traumatic brain injury (TBI) is a common reason of brain tissue loss as a result of tumors, accidents, and surgeries. Renewal of the brain parenchyma is restricted by many reasons such as inimical substances produced as the result of trauma and also inflammatory responses. A strong cascade of inflammatory responses begins as a result of TBI which include recalling peripheral leukocytes into the...

background : the brain is a rare site of metastases from ovarian cancer. limited data are available on prognostic factors, standard treatment, and survival. knowledge of clinical prognostic factors would help the management of patients with brain metastases. the aim of this study is to evaluate the impact of clinical factors and treatment modalities on survival in patients with brain metastases...

Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Human neural stem cells cultured in self-assembling peptide scaffolds have been proposed as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/...
