Research in Iran: Look on the Bright Side
Regarding to Dr. Richard Stone’s report entitled “Iran, a shady market for papers flourishes” published in Science 15th September 2016. There are several points in the articles that require particular attention. The report, although presents some truth, lacks depth and balance on a problem that is not unique to Iran. To begin to understand this, perhaps one needs to remi...
متن کاملColour through the thalamus.
Visual perception in humans and other primates depends on the retino-thalamo-cortical pathway. This pathway begins with retinal ganglion cells, which have axonal terminations in the lateral geniculate nucleus (LGN) of the thalamus. Each ganglion cell axon provides input to one or more LGN relay neurones and, in turn, nearly all the LGN relay neurones project to the primary visual cortex. Thus, ...
متن کاملThe cognitive thalamus
The thalamus, once viewed as passively relaying sensory information to the cerebral cortex, is becoming increasingly acknowledged as actively regulating the information transmitted to corti-cal areas. There are a number of reasons for this change. First, evidence suggests that first-order thalamic areas, like the lateral geniculate nucleus, ventral division of the medial geniculate nucleus, and...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
The 'bright brain'.
In this preliminary study we report on a new neonatal cerebral ultrasound appearance consisting of high amplitude echoes that arise diffusely throughout the brain and obscure the echoes of normal structures. This scan appearance was associated with probable cerebral insult and we believe that it is caused by cerebral oedema.
