grey, white

200

These type of fibers carry efferent signals out of the brain and down the spinal cord.

What are projection fibers

300

Located in the middle of our brain, this is known as the afferent "relay station" of the brain. Most afferent neurons will synapse here before going to their respective cortices.

What is the Thalamus

Origin: Choroid plexus

1. Lateral ventricles

2. 3rd ventricle

3. 4th ventricle

4. Cerebral aqueduct

Damage to the medulla oblongata will likely impair this part of many neural pathways

What is decussation

You just finished taking a test and you are thinking about quietly getting up and leaving the class so not to disturb anyone. You are likely using this area of the brain.

What is the premotor cortex

500

A person has sustained a traumatic brain injury, and is unable to smoothly perform motor skills. Sometimes their limbs will involuntarily jerk. Damage has likely been incurred to this brain structure.

Challenge Questions?

300

This patient is recovering from a stroke. Based on the conversation he is having with his speech therapist, what brain structure likely incurred damage.

Wernicke's Area

400

A child has just woken up screaming from a very bad nightmare. He cannot remember the dream that well, but it still managed to foster extreme emotional response. This brain structure was the primary driver for his dream.

What is the amygdala

500

A patient reports a variety of hormone deficiencies after a car crash that caused a traumatic brain injury. Hormones like thyroid hormone, growth hormone, oxytocin, etc. are all deficient in this patient to the point where they are unable to perform necessary homeostatic functions without outside injections. Based on your knowledge of the brain, you know this structure has likely incurred damage.

What is the hypothalamus
