Chemical AAQ helps blind mice to see

The video discusses degeneration in the retina, which can lead to blindness by affecting rods and cones. However, the underlying nerve network often remains intact. A compound called AAQ has been developed to help restore vision by acting as a photo switch that binds to protein ion channels in the retina. When exposed to light, AAQ activates, allowing ions to flow and neurons to react similarly to rods and cones. An experiment with mice demonstrated that those injected with AAQ responded to light like normal-sighted mice, while untreated mice did not.

What is the primary cause of blindness discussed in the first section?

• Glaucoma

• Cataracts

• Damage to the optic nerve

• Degeneration of rods and cones

What role does AAQ play in the treatment of blindness?

• It repairs damaged rods and cones

• It replaces the retina

• It strengthens the optic nerve

• It acts as a photoswitch for protein ion channels

How does AAQ help neurons in the retina?

• By allowing ions to flow through channels

• By blocking harmful light

• By increasing blood flow

• By regenerating damaged cells

In the experiment, how do mice with AAQ injections behave?

• They behave like normal seeing mice

• They become more active

• They avoid the light

• They show no change

What is the purpose of the LED light in the experiment?

• To test the mice's reaction to light

• To measure the speed of the mice

• To provide warmth

• To guide the mice
