Question

Which of the following statements about brain injury is FALSE?

		Chronic traumatic encephalopathy (CTE) is caused by repeated brain trauma including those that are subconcussive.
		A seizure is a transient event characterized by synchrony in the discharge of the involved neurons.
		Epidural stimulation is used to bring spinal neurons below (caudal to) a spinal cord injury close to threshold so that weak voluntary input from the motor cortex can bring those neurons to threshold resulting in movement.
		Central axons normally regenerate as extensively as peripheral axons.

Answer 1

ANSWER- here the correct option is E

the central nervous system axons do not regenerate spontaneously as the axons of the peripheral nervous system regenrates.

apart from this, the rest of the options are correct in terms of the brain function and injury.

CTE is caused by the conitnous brain trauma and hence it is correct, epidural stimulation is used give conitnuous current to the lower part of the spinal cord, hence correct, mortor cortex helpss in bringing the neurons to the threshold , hence correct.

therefore, only the last option is incorrect as concern to the brain function, and in terms of this question, the correct answer is E
