I Still Don't Have a Brain
This lobe of the brain is for visual processing.
What is the occipital lobe?
The white part of your eye.
What is the sclera?
This is the outside of the ear used for catching sound waves.
What is the auricle/pinna?
This type of communication is used within one neuron.
What is electric?
This part of a neuron integrates the signals to determine if threshold has been crossed.
What is the soma?
This lobe of the brain processes auditory signals and speech/language.
What is the temporal lobe?
The part of the internal eye that can move to adjust the focus of light signals.
What is the lens?
This is the hole going from external ear to middle/inner ear.
What is the external acoustic meatus?
During this phase of an action potential, sodium channels are open.
What is depolarization?
This is when our brains create a smaller response over time to the same stimulus.
What is habituation?
This is the division between the right and left hemispheres of the brain.
What is the longitudinal fissure?
This structure is the blood supply for the retina.
What is the choroid?
This is the scientific name for your ear drum.
What is the tympanic membrane?
During this phase of an action potential, potassium channels are open.
What is repolarization?
This is what makes a reflex different than any other sensation we've discussed.
What is it does not go to the brain?
This part of the brain is responsible for sleep and consciousness.
What is the pons?
This is the smooth muscle that adjusts how much light enters the eye.
What is the iris?
This structure in the ear converts sound waves into a neural signal.
What is the cochlea?
At the end of an action potential, neurotransmitters are released from here.
What is the axon terminal?
This causes the blind spot in our vision.
What is lack of photoreceptors where the optic nerve meets the retina?
This part of the brain is for fear and emotional response.
What is the amygdala?
These muscles allow our eye to change our focus of light.
What are ciliary muscles?
This is the nerve that sends sound signals to the brain.
What is the vestibulocochlear nerve?
During this phase of an action potential, a neuron is "frozen".
What is the refractory period?
These cells allow us to maintain our sense of balance.
What are hair cells?
