Miss Alaneus

Mrs.Alaneus

“I can activate your senses to a state of alertness. Who am I?”

Reticular formation

“You never even pay attention to me. I control breathing and heart

rate, but I never get any credit. Who am I? (You probably don’t even

know who I am.)”

Medulla

“You would never be able to walk across a tightrope if I was deficient

in you. Who am I?”

Cerebellum

“I help you remember things in the short-term. Who am I? (It would be

rather ironic if you forgot.)”

Hippocampus

“I control aggression and fear. What? Are you afraid of me? Want

to fight? Who am I?”

Amygdala

Cerebral cortex

Thalamus

Medulla

Cerebellum

Pituitary gland

Surgery which destroys brain tissue

Lesion; EEG; CT scan; PET scan; MRI; fMRI

Lesion

Brain x-rays

Lesion; EEG; CT scan; PET scan; MRI; fMRI

CT scan

Could measure brain activity during a mental task

Lesion; EEG; CT scan; PET scan; MRI; fMRI

fMRI

Recording brain activity through electrical measurements

Lesion; EEG; CT scan; PET scan; MRI; fMRI

EEG

This requires a tracer, sometimes radioactive glucose, to detect brain

activity

Lesion; EEG; CT scan; PET scan; MRI; fMRI

PET scan

Epileptic seizures may force this to be cut

Corpus collosum

Using a series of incoherent words in regular speech may suggest apahsia

to this area

Wernicke’s

The inability to speak may be caused by aphasia to this area

I’m kind of a big deal in the endocrine system…but the

hypothalamus tells me what to do.

Pituitary gland

When neurotransmitters go home, this is known as…

reuptake

When an action potential is traveling down the axon, the neuron is…

Polarized; depolarized?

Depolarized

I am produced by the pituitary gland and help you feel less pain.
