Robert Sapolsky on the Limbic System (por StanfordUniversity)

olfactory bulb takes up 40% of a rodent brain’s projections

rhine encephalon — originally viewed as to do with olfaction in all species

gathers whatever sense-data pertains to emotions

Paul McLean’s triune brain (phylogenetic conservation): hypothalamus⊕pituitary⊕brainstem⊕midbrain⊕thyroid⊕pancreas⊕heart (robotic, boring—until it goes wrong) + the limbic system (mostly a mammalian invention: birds, reptiles, fish have less complex limbic systems) ⊕ emotional complexity + cortex (gleaming analytical machine of cognitive expertise — greatly expanded in vertebrates, in mammals, in primates, in us — cortex tied to limbic system, not independent)

decisions made under duress

think about your own mortality (kicking out “CRH”)

so limbic influences cortex and vice versa

we are “a fancy species”

Odene’s curse — lose the capacity for automatic breathing (you die of sleep deprivation)

Antonio DiMasio, Descartes’ Error

James Pabes

the limbic regions compete to control the hypothalamus (they can shush each other up)

edge/network/synaptic distance to the hypothalamus

every sense has to go through ge;3 synapses to tell the limbic system anything—except olfaction can hop 1.

olfaction takes up only 5% of our brain

grey matter (nuclei) vs white matter (axon cables wrapped in myelin)

amygdala, hippocampus, septum, mammilary bodies, hypothalamus, thalamus, prefrontal cortex

frontal cortex: where am I being touched? which note are you playing? how do I do long division? which limb do I want to move? plus long-term planning, gratification postponement, emotional regulation, impulse control

frontal cortex is most recently evolved, relatively largest in humans, not fully mylenated until age 25;size of prefrontal cortex in primates grows as size of typical social group

amygdala tells you to be afraid and pings the hippocampus: “Hey, remember to be afraid of this in future”

Linda Belcher’s Porcelain Babies

So I've spent the better part of my Sunday night learning Sufjan Stevens songs on my mandolin and it got me thinking: do you still play ukulele? cuz if so/if you want to pick it up again, we should have tiny instrument jam sessions on a regular basis once you move to the city...

I think that’s a stellar idea. I also bought an electric cello this year, so we could really make some pretty things together :)

I want to make a point of being open to all future love from any individual be that romantic or otherwise. I believe that love is achieved through openness, and I’m ready to be the for others in the way that they are ready to be there for me.
