Lobes of the brain

Freud Took Off his Pants

Frontal, Temporal, Occipital, Parietal

Occipital Lobe

processes visual information

Parietal Lobe

Processes sensory information…

Use a “piranha” fish as your mnemonic. The piranha bites you on the top of the head (where the parietal lobe is located). That’s a sensation the parietal lobe would process.

Frontal Lobe

where complex thinking occurs…

Use “front door” as your mnemonic. Put the front door on your forehead and put Einstein (complex thinker) behind the door.

Temporal Lobe

where auditory processing occurs…

Use “tempo” as your mnemonic and picture a metronome above your ear (where the temporal lobe is located)

Resting and Action Potential

When the neuron is in its resting state the majority of the ions inside the neuron are negatively charged and the majority of the ions outside the neuron are positively charged.

Broca’s area

the area of the brain responsible for producing speech. If it is damaged, you can understand what someone says, but your speech is disjointed.
