Behavioral and neural correlates of diverse conditioned fear responses in male and female rats
Abstract Pavlovian fear conditioning is a widely used tool that models associative learning in rodents. For decades the field has used predominantly male rodents and focused on a sole conditioned fear response: freezing. However, recent work from our lab and others has identified darting as a female-biased conditioned response, characterized by an escape-like movement across a fear conditioning chamber.
Sounding the Alarm: Sex Differences in Rat Ultrasonic Vocalizations during Pavlovian Fear Conditioning and Extinction
Discussion Across these studies, we provide a rich picture of rat USV production during fear conditioning, demonstrating how USVs can relate to other behavioral readouts of internal states, and sex differences therein. Alarm calls in male rats were more frequent than in female rats, tracked more robustly with the intensity of the aversive experience (shock intensity), and were more resistant to extinction.
Julia Mitchell | ‘Thriving at Penn’ is more meme than reality
Snake Pit Memos | At their core, these efforts have incredibly vague missions By Julia Mitchell 17 hours ago On April 4, students participated in the Day of Play with Goats on College Green. Credit: Izzy Crawford-Eng At a “Day of Play” event designed to foster wellness in the Penn community, surrounded by celebration and positive messaging from the balloons, photo ops, and free food, I felt like joy was being shoved down my throat.
Julia Mitchell | Penn’s pre-college programs won’t get you accepted
By Julia Mitchell 09/02/19 9:22pm Credit: Alec Druggan Picture Penn’s campus mid-July – it’s a humid Philly summer, but you and most other students are far, far away, probably either at the beach or at an investment bank. Still, somehow I found myself right back in University City, working as an RA and TA at one of the many high school business programs on campus.
Julia Mitchell | Stop blaming sexual assault on alcohol
Snake Pit Memos | Acknowledge the risk of situational drinking while refusing to tolerate sexual violence By Julia Mitchell 18 hours ago Credit: Carson Kahoe We are quick to fight over blame when alcohol is linked to sexual violence. The first step was admitting to the problem, but we did that. On a national scale, it took an epic power shakedown for leaders to acknowledge the ubiquity of sexual assault across institutions.
Julia Mitchell | International students deserve transparency from Student Financial Services
Snake Pit Memos | Even an informative email would be a step in the right direction By Julia Mitchell 18 hours ago SRFS has been collaborating with administrators to plan the initiative for years. Credit: Mona Lee Navigating Student Financial Services can be headache-inducing for anyone. After giving yourself a pep-talk, you walk into an office, input your name into a kiosk, and watch it linger endlessly on a waiting list while you squirm in a chair.
Julia Mitchell | What Birthright taught me about Judaism at Penn
Snake Pit Memos | How Birthright made me rethink my identity By Julia Mitchell 13 hours ago Credit: Claire Shin If you haven’t heard about Birthright, it sounds like fantasy: an organization that offers a free 10 day trip around Israel to thousands of young Jewish adults each year. My first thought when I heard about this program through Penn Hillel? There is definitely a catch. My second thought? I am definitely not Jewish enough for this. Of course there was a catch.
Julia Mitchell | Penn students are fascinating creatures - listen to their stories
Julia Mitchell | Penn students are fascinating creatures — listen to their stories Snake Pit Memos | In my first semester, conversations with classmates taught me more than all of my lecture slides By Julia Mitchell 5 hours ago Credit: Isabel Liang A string of half-finished, half-baked conversations has followed me at Penn. You know the type — a quick catch-up on Locust, a rushed lunch date at Commons, small talk thrown around in dorm hallways.
Julia Mitchell | Don’t donate to Penn
Higher education is a philanthropic cause that pries open the wallets of billionaires. But, that money should go to the institutions that can best serve students, not to those with the most attractive brand names. Every now and then, the world of higher education falls into a frenzy over the latest mega-donation. In 2015, John Paulson dumped $400 million on Harvard University. The following year, Phil Knight threw the same sum Stanford University’s way.
Julia Mitchell | Results of the midterms are as underwhelming as both parties’ agendas
The day after President Trump took the Oath of Office in front of a crowd of either 200 or 2 million people — the truth got lost somewhere along the way — I boarded a crowded bus to Washington to march amid the surge of pink hats. Trekking through the capital, I pretended to know exactly what I was marching for, to assemble a list of policy goals or at least some elegant notion of feminism as a rallying cry.
Julia Mitchell | Don’t let Penn’s club recruitment rush rob you of your individuality
The social circles of American teen movies are well documented — cliques, petty gossip and all. While the intense social hierarchies of “Mean Girls” don’t resemble a typical high school, most Penn students — regardless of background — assumed a degree of order in their social lives before college. Essentially, we arrive at Penn secure in our little corner of the universe; we know who our friends are and where to sit at the lunch table. Suddenly, this comfort shatters.
Julia Mitchell | Tired of partisan squabbles? Take a note from local politicians
United States politics is a bloated creature — every Twitter fight adds a burst of hot air. The division between Democrats and Republicans fits political discourse into a narrow, obsessive outlook that is all talk and no decision-making. Granted, right now partisan division seems like a vast and ever-widening gulf, but the way we experience politics should not be exclusively from dramatized broadcasts of Senate squabbles. These conflicts are irrelevant in our day-to-day lives.
