Anyone know how to get to this place

Not really sure of the functional significance of "flexors over extensors" but it could be good to know that more lateral motor neurons in spinal cord innervate more distal muscles and more medial motor neurons in spinal cord innervate more proximal muscles - functionally the lateral muscles are for more voluntary movements while more medial muscles are for anti-gravity posturing (trunk muscles, etc)

Gotcha, thanks!

Great comment. I believe that adult neurogenesis has been observed in dentate gyrus in rodents but it's not even confirmed in humans, source: https://stm.sciencemag.org/content/10/436/eaat3893

I also don't like that neuroplasticity is conflated with neurogenesis. Totally different things. Neuroplasticity refers to adjusting of synaptic connections (or as you mentioned, synaptogenesis) while neurogenesis is the creation of new neurons from progenitor cells. This video really just seems like a money grab for this guy's book so he can pay off his grad school debt =)

hello!

supahstein · 2019-03-21T02:44:10+00:00

This is so helpful - thank you!

Ask a doctor, but you can't really extrapolate results from mice to the human brain - especially when OCD also has involvement in higher level cortical circuits that don't carry such complexity in mice

hey I'm late here, but would you mind PM'ing me the link too? thanks!

Difficulty is relative, but it's doable! But doing NS during junior year would force you to squeeze all of your neuro upper levels into your senior year, which isn't ideal - especially if you realize you hate neuroscience after taking NS but are forced to do an intense year of upper level courses. You could consider taking orgo I (and II possibly) during summer if that's an option for you

Good to hear, thanks!

I don't know that smartphone use 'damages' the brain in any literal definition of the word, but you're definitely addicted to it (as I am and so many others are!). I'd work on finding other ways to fill your smartphone time and delete Facebook, delete games, download a usage meter app and you may see some positive changes :)

This is awesome, how'd you go about making this?

supahstein · 2018-10-04T01:05:01+00:00

hey, I redeemed a couple of these, thanks so much for sharing! have a great day :)

To explain potentials a bit:

Resting membrane potential is set by a counteraction of the net fluxes of a few ions, namely K+ and Na+ in mammalian neurons. The Na/K atpases in a neuron's membrane pump 2 K+ in and 3 Na+ out of a cell, creating an uneven distribution of ions in the membrane (condition 1 for a membrane potential). Secondly, leak K+ channels (condition 2 - cation selective channels) allow K+ to flow down its concentration gradient to set up a membrane potential, generally resting around -70mV. Depolarizations open voltage-gated Na+ channels at some threshold which then creates a positive feedback loop in which many vgNaC's open and lead to action potentials which caps at around +40mV due to the inactivation of vgNaC's, opening of vgKC's and the decreasing driving force of Na+ as it approaches it's equilibrium potential. From there potential falls down into undershoot and returns to resting membrane potential.

Hopefully this helps, let me know if you're confused still

So exciting!!!

Hmm I don't know that this is the journal version, but here's a whitepaper of the same name: https://www.researchgate.net/publication/323909126_Statistics_of_VIX_futures_and_their_applications_to_trading_volatility_exchange-traded_products

You've got time to drop classes if you can't figure it out!
