A biomedical treatment for severe depression in which a brief electrical current is sent through the brain of an anesthetized patient is Electroconvulsive Therapy (ECT)
Electroconvulsive Therapy (ECT) is done under anesthesia in which currents which are small in magnitude are passed on through the human brain in patients with severe depression.
ECT is used when the patient does not respond to other treatments which involves Electrically stimulating the brain while patient lies in anesthesia.
This stimulation causes a seizure which helps to relieve the symptomatic causes of the depression.
It does not lead to any damage to the brain and its cells.
Thus, it helps to treat the various mental disorders prevailing in the popoulation.
ECT is considered as the last usable option when all the treatments pre given have failed to treat the patient.

Answer:
1 When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photo receptors turn the light into electrical signals.
These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.Focal vision is involved in examining and recognizing objects related with the macular area of the retina whereas peripheral vision is vision resulting in stimulation of the retina outside the macula. An example of peripheral vision would be looking straight ahead while also being able to see on the side by the eye.
Explanation:
2The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. The sella turcica is a saddle-shaped depression that surrounds the inferior, anterior, and posterior aspects of the pituitary.When a pituitary tumor pushes the optic chiasm, it causes visual loss in both eyes. In addition to the optic nerve, which brings vision from the eye to the brain, there are also several other nerves near the pituitary gland that travel to the eyes and help them move normally.
