The frontal lobe of the human brain is both relatively large in mass and less restricted in movement than the posterior portion of the brain. [ 1] It is a component of the cerebral system, which supports goal directed behavior. [ 2] This lobe is often cited as the part of the brain responsible for the ability to decide between good and bad ...
The incidence of eye injuries during general anaesthesia has been studied, and different methods of eye protection have been compared. [citation needed] When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%. [ 1][ 2] If tape is used to hold the eyes closed, ocular injury occurs ...
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [ 1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two ...

Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in dim light ...
Cosmic ray visual phenomena, or light flashes ( LF ), also known as Astronaut's Eye, are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina, [ 1] the LF discussed ...
