It's conference season! #SfN2025

See my poster from the @aliciaizquierdo.bsky.social and Wikenheiser labs @sfn.org on Tuesday @ 1-3pm.

☀️ DM me to meet up in beautiful San Diego ☀️
Pay us a visit at #SfN2025 🧠 in San Diego ☀️!
(4/4) I'm doing a couple more experiments before I finish up my PhD & oooweee it's nice to use a task that rats learn quickly w/ a lot of interesting outputs.

Work done in part thanks to @hhmi.org w/ the best collab btwn @aliciaizquierdo.bsky.social & Andrew Wikenheiser. best co-mentorship eva!
(3/4) A couple years back, Andrew and I were talking about how PR, given a consistent work rate, kinda looked like a depleting patch (re: foraging). Now, applying optimality modeling, we find that our rats "overharvest" similarly to (other) patch-leaving tasks 🤯.
(2/4) Bout (length of time pressing for reward between no-access delay periods) length & frequency are sensitive to delay length. ***Note, the differences in the y-axis.
(1/4) TL;(please still)R on #eNeuro

Rats can reset PR to its easiest difficulty by paying a delay cost on PRR task. They adaptively use the reset lever to go from receiving ~67 pellets (PR) ➡ ~210 pellets (PRR w/60s delay)➡ ~328 pellets (PRR w/10s delay; almost 15g 😳) w/in the same amount of time.

Next @zeenarivera.bsky.social from UCLA for the first blitz talk on a progressive ratio task using effort.

New research suggests parental care could shape the skin microbiome in amphibians.

remember when emily came in clutch to be my independent study professor after i dropped out of a required senior seminar class in my humanities college in progressive seattle where some of my peers referred to the filipino & the mexican students as The Colored people 🤪

preorder her book already !!!
but actually what a fascinating way to engage with studying animal behavior.

my guide asked me if the prevalence of fly fishing has changed fish foraging patterns over time. i told him i'd look into it, and now i'm texting him that--yes!! (at least some) fish do some social learning to avoid lures
learned how to fish. when does my lifetime supply of food get delivered

A friend who works at Harbor-UCLA just told me that ICE was on the premises. Harbor-UCLA is a safety-net hospital & a level 1 trauma hospital. People are going to die because of these actions. This makes me so angry.

Per CNN and ABC News: LAPD has declared all of downtown as an unlawful assembly, telling all demonstrators to leave the area immediately.

Everyone covering/protesting, please stay safe.

So on one hand Los Angeles is having to fight back against ICE and state violence and on the other hand Israel just abducted everyone aboard the Madleen including Greta Thunberg and confiscated all aid so everything’s pretty fucking bad

yep and super yep about the absolution part which allows most ‘good’ people to detach and ignore the contradictions. thats who it quiets down the ppl should be pissed

every day it’s ignored it’s quickly normalized as a ‘policy issue’ while the killing continues under the headlines
