Conserved visual capacity of rats under red light

Recent studies examine the behavioral capacities of rats and mice with and without visual input, and the neuronal mechanisms underlying such capacities. These animals are assumed to be functionally blind under red light, an assumption that might originate in the fact that they are dichromats who possess ultraviolet and green but not red cones. But the inability to see red as a color does not necessarily rule out form vision based on red light absorption. We measured Long-Evans rats' capacity for visual form discrimination under red light of various wavelength bands. Upon viewing a black and white grating, they had to distinguish between two categories of orientation, horizontal and vertical. Psychometric curves plotting judged orientation versus angle demonstrate the conserved visual capacity of rats under red light. Investigations aiming to explore rodent physiological and behavioral functions in the absence of visual input should not assume red-light blindness.

These animals are assumed to be functionally blind under red light, perhaps originating in the fact that they are dichromats who possess ultraviolet and green but not red cones. But the inability to see red as a color does not necessarily rule out form vision based on red light absorption through their rod-dominated retina.

PROBLEMS OF RURAL GIRL STUDENTS IN HIGHEREDUCATIONAL INSTITUTION

Higher Education means Tertiary Education, which is under taken in colleges (or) universities, and it may be delivered virtually (or) at a distance. There are a large number of problems that girl student’s face for developing their career potential. Some of the serious problems are as Follows: -Problems related to Home, Educational Institutions, Society, Economic problems, Educational problems. Rural girls belong to disable as per the data, Girl dropout ratio has increase with the enhanced pattern of gender inequality in access to education, which seems to be attainment and from urban to rural and to disadvantaged group in the society.Gender equality and the empowerment of women are gaining ground worldwide. There are more women Heads of state (or) Government then ever and the highest proportion of women serving as government ministers women are excursing ever-greater influence in business. More girls are going to school, and are growing up healthier and better equipped to realize their potential. Girl student’s suffer in many case, both form discrimination and from inequality treatment. It is easy to imagine that the difficulties encountered by rural girl students in obtaining higher education. Providing access to local relevant high-qualities education and training opportunities in critical to retaining rural girl students in Higher Educational Institutions.
