We suggest that ensemble definitions be broadened to fully capture how the brain works without superimposing our own biases of how we think the brain should work.
Many thanks to @giocomo for inviting me to write this with her and allowing me to explore a topic I'm fascinated by!
How we define these ensembles is somewhat based in physiology, but largely based on analysis preferences and experimental conditions.
Different ensemble views can lead to vastly different conclusions, and particularly fascinating findings have arisen from recent papers that examine coding from multiple views.
How neurons represent navigational variables is studied at a wide range of ensemble scales - from single neurons to small groups to whole populations. We divided them into 6 views.
My review with @giocomo is now out in Current Opinion in Neurobiology! https://authors.elsevier.com/c/1gH1-3Q9h2Aqkv
(let's see if I can figure out how to #paperthread on here π)
What math do neuroscientists need to know?
A highlight of #SFN2022 was Ella Batty's answer to this question. She showed off an incredible math for neuroscientists course she has developed at Harvard with open materials (https://ebatty.github.io/MathToolsforNeuroscience/) and discussed her amazing work with Neuromatch Academy (https://compneuro.neuromatch.io/)
Her SFN slides are here: https://osf.io/s94b2
Working with the @InternationalBrainLab's massive dataset can be daunting. I made this notebook to help you:
- Query recordings from a certain brain region (or multiple simultaneously recorded regions)
- Load in the neural activity
- Align the data to task events
- Plot PSTHs

How do cognitive maps differ from spatial schemas?
Review of how cognitive maps (of a specific city) differ from spatial schemas (expected city layout) & event schemas (expected city events)

Hello π time for an π #introduction
I'm a neuroscientist at Stanford in @giocomo's lab studying how neural firing sequences in entorhinal cortex evolve over learning. I'm also the co-chair of the Inhibition in the CNS Gordon seminar in 2023 https://emilyjon.es/grs/. I love studying all things #inhibition, spatial learning and memory, and #Alzheimer's disease.
Also I have a dog named Heimdall, king potato and president of derpistan.
