Concussion

What is the leading cause of sports-related concussions in children?

• Basketball

• Bike riding

• Soccer

• Football

What are helmets traditionally designed to protect against?

• Neck injuries

• Concussions

• Facial injuries

• Skull fractures

According to the speaker, what is a common misconception about the movement of the brain during a concussion?

• The brain moves a lot inside the skull.

• The brain does not move at all.

• The brain moves very little inside the skull.

• The brain exits the skull.

What device is used in the speaker's lab to study concussions?

• A headband with sensors

• A neck collar with sensors

• A mouthguard with sensors

• A helmet with sensors

What critical factor do most experts think is involved in concussions?

• The rotation of the head

• The size of the helmet

• The speed of impact

• The weight of the person

What does the speaker suggest might be a common mechanism of concussion?

• Impact to the front of the head

• Rotation causing forces to strike the corpus callosum

• Compression of the entire skull

• Direct impact to the top of the head

What is the corpus callosum?

• A fluid that surrounds the brain

• The largest fiber bundle connecting the right and left sides of the brain

• A membrane that protects the brain

• A part of the skull

What innovative device is mentioned that uses air to prevent concussions?

• A cushioned cap

• An airbag neck collar

• A protective headband

• A modified football helmet

Why is the airbag device for preventing concussions not for sale in the US?

• It has not been tested

• It does not meet regulatory standards

• It is too expensive

• It is still in the prototype phase

What does the speaker hope to achieve with his research?

• To make concussion-preventing technology widely available

• To develop a new sport

• To ban contact sports

• To eliminate the use of helmets
