Hi, I'm Alexis. 🧠 I'm a neurophysiologist by training and mostly post Neuroscience, but also lead a team of science SMEs at MathWorks supporting other Biological sciences, Chemistry, Geoscience, Mathematics and Physics.
I'm also a proud pre-scientist pen pal and recommend it!

If you're planning a study, search DANDI or OpenNeuro first to see if relevant data already exists. If you're teaching, incorporate open datasets into your curriculum, writes @bendichter.com

A different way to protest.

Researchers presented posters on how their terminated projects would have benefitted society.

Many of the scientists presenting were a few years into their projects before their funding was cut — wasting money already spent.

You know you hang with a certain age group when "Kragle" and "Pass the Parcel with Lucky's Dad's rules" come up in conversation and nobody misses a beat.

Is Waze smart enough that we could ask for a button to say, "I'm stuck behind a vehicle going X mph slower than I want to. Based on the route I'm on, what's a route, even if it's longer by distance, that can help me make up time?"

Sensory inputs trigger a fast-traveling wave, followed by a slower wave carrying top-down info (value/choice). The late wave reactivates ensembles in superficial cortical layers.

Touch-evoked traveling waves establish a translaminar spacetime code

Translaminar spacetime patterns organized by feedback-dependent cortical circuits support sparse traveling waves.

Question for people going from intan based ephys to neuropixels. Do you have an alternative for the accelerometer from the intan headstage? That was a nice feature that is missing on freely moving neuropixels recordings 🧠📈

Some favorite practical summer courses are the ARTCs at the MBL in Woods Hole, MA. I anticipate visiting a few this year to talk #Neuroskyence, sharing #openscience data stories, and using #MATLAB.

The Transmitter @thetransmitter.bsky.social · Jan 13

John Tuthill explains why practical summer courses in neuroscience matter and how this tradition helps researchers rekindle the unfettered joy that initially brought them to the field.

The wonders of population coding! Recent paper by @juliencorbo.bsky.social et al. @polacklab.bsky.social -> visual cortex in trained mice encodes orientation differently from in naive mice... almost more "messily"(?)... but behavior is good. #neuroskyence #matlab 🧪 🧠
