This survey summarizes many theories and methods applied for vision and speech improvement for cerebral palsy babies. Some research team focus on vision and speech stimulation for cerebral palsy with different techniques using computer aided system and electrical devices. Electrical electrode devices are complexity to use and reliability are inadequate for providing vision and speech stimulation which...
Visual input in the critical period is an important determinant of the functions of the visual system, affecting for example the formation of the ocular dominance column in the visual cortex. The final map of columnar organization is usually determined by plastic changes in the critical period, but organization is distorted without adequate visual input. Here, we examined whether formation of the...
Research in the fields of cellular communication and signal transduction in the brain has moved very rapidly in recent years. Nitric oxide (NO) is one of the latest discoveries in the arena of messenger molecules. Current evidence indicates that, in visual system, NO is produced in both postsynaptic and presynaptic structures and acts as a neurotransmitter, albeit of a rather unorthodox type. Under...
