I was thinking about some of the comments I received on my F32 NIH postdoctoral fellowship application from 6-7 years ago. It’s surprising how frustrated I still get when I think about it. A thread... 1/

@DavidBarker_PhD @fedsanabria @TedPavlic @tgup_in_the_lab @jmcin9 We have done it with odor detection tasks in mice.

Congrats to Marley Kass @DrMarleyDeena on receiving the Outstanding Doctoral Student Award for her accomplishments here at @RutgersU!

Check out our (@McGannLab) newest paper in NLM: https://t.co/J5OIebkMUA … …
In it, we find that when conditioned fear generalizes across threatening and non-threatening odors that there is a corresponding generalized hypersensitivity of olfactory bulb interneuron activity.

[John McGann @McGannLab]

Agreed - it's intriguing. Great job @RiffellLab ! https://t.co/YQeMOhHpSc

@scienceofscent @CNoppeney @science They don't name Broca (why would they?), but they use Turner's terms that were explicitly based on Broca. Ergo, Broca's influence. 3/3

@scienceofscent @CNoppeney @science Here's an example from Braak and Del Tredici's book on Alzheimer's from 2014, pg 39: "In the microsmatic human brain, most structures... 1/?

@scienceofscent @stevenmunger @jokriolo Me: Idea of poor human olfaction "derives" in part from Broca, with Turner labeling it microsmaty. 2/2

[John McGann @McGannLab]

@scienceofscent @stevenmunger @jokriolo Broca: Humans="non-smellers"
Turner: Broca shouldn't have said "non-smeller," let's say "microsmatic"
People since: humans=microsmatic 1/2

@scienceofscent @CNoppeney @science Not my preferred format, but we can't all write books like you, Avery. 😀

[John McGann @McGannLab]

@scienceofscent @stevenmunger @jokriolo Broca was really commenting on free will beliefs, but subsequent scientists exaggerated his "anosmatique" classification into modern myth.

[John McGann @McGannLab]

@scienceofscent @stevenmunger @jokriolo Broca classified humans as "anosmatiques". Non-smellers. Said olfaction atrophied in primates. 1879 paper in Revue d'Anthropologie, p.385.

@scienceofscent @CNoppeney @science Tight limits on word count and citation count were challenging, plus need to engage both expert and lay audience. What would you have added?

[John McGann @McGannLab]

@scienceofscent @CNoppeney @science Poor human smell is widely believed and is taught as fact in many textbooks, but as you know is not true. That's myth, not just hypothesis.

@VasquezSoyYo @WRadioColombia Sure. Email me at [email protected].

And it's an awesome quote. Thanks! https://t.co/qme8zc62aM

[John McGann @McGannLab]

Lovely coverage by the NY Times. https://t.co/Xa1bkBbmdd

[NYT Science @NYTScience]

The misunderstood 19th-century science that led to the myth that human noses are weak https://t.co/MTXuDKiCF6

[John McGann @McGannLab]

That is amazing. Paul Breslin for the win. @MonellSc https://t.co/c6gxZMSj5V

So this is the best quote I've ever gotten from a researcher or really anyone ever https://t.co/Xy00tliblf
