The Universe

In the article, which is the result of scientific research in recent decades, the professor points to the value of revolutionary inventions that play a huge role in the development of research, in the evolution of the universe and the brain. One such invention is the telescope. As for the brain, the introduction of research tools such as computed tomography (1972), MRI (magnetic resonance imaging), followed by EEG (electroencephalography), PET (positron emission tomography), MEG (magnetoencephalography) and more recent inventions for tracking of the eyes condition. Such discoveries in science have made the researcher wonder: does knowledge about the brain really allow us to make learning more effective? The scientist provides a classification of children according to their age psychological periods and the work of neurons in the brain. It is indicated that at the age of 4–5 years the network of neurons is best developed. The period of a rebellious teenager is characterized by the maturation of the brain, or the processes of strengthening between neurons. The author speaks about the importance of knowledge in the achievements of neuroeducation in order to understand the strange and most unexpected statements of our students. The article calls for monitoring the results of the latest research on the universe and on our brains. The author is convinced that in the process of teaching educators are able to make certain changes in the brains of their students.

Medical imaging plays a pivotal role in the detection, diagnosis, and clinical management of primary soft tissue tumors. Various imaging modalities have been used, and each modality offers unique advantages in the workup of soft tissue tumors by localizing the lesions in different compartments of the body and characterizing macroscopic tissue composition of the lesions in a noninvasive and safe manner. We review the clinical role and technical aspects of the frequently used imaging modalities, including magnetic resonance imaging (MRI), computed tomography, ultrasonography, positron emission tomography, and plain radiography with an emphasis on MRI as a mainstay imaging modality and a brief discussion of advanced techniques. We also review imaging features of common soft tissue tumors that can be detected and characterized using current imaging techniques. This review contains 54 figures, 1 table and 37 references.   Key words: computed tomography, diffusion-weighted imaging, imaging, magnetic resonance imaging, positron emission tomography, soft tissue, technique, tumor, ultrasonography

The Brain

Evolution has endowed human race with the most adroit brain, and to harness its potential to the fullest the concept of brain computer interface (BCI) has emerged. One of the most crucial components of BCI is the technique of brain imaging. The first approach in the field of brain imaging was to measure the electrical and magnetic activity of the brain, the techniques being known as Electroencephalography and Magnetoencephalography. Striving for furtherance, researchers came up with another alternative known as Magnetic Resonance Imaging. But it being confined to only structural imaging, the functional aspects of brain were mapped using functional magnetic resonance imaging. A similar but comparatively newer neuroimaging modality is Functional Near Infrared Spectroscopy. Transcranial Magnetic Stimulation neuro-physiological technique is based on the principle of electromagnetic induction. Based on nuclear medicine the brain imaging technologies that are widely explored in the world of BCI are Positron Emission Tomography and Single Positron Emission Tomography.
