Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

Online now:

Network influence determines the impact of cortical ensembles on stimulus detection

By photostimulating specific visual cortical ensembles, Bounds et al. discovered that an ensemble’s impact on local neural activity, not its visual encoding properties, predicts its impact on stimulus detection. Their analysis reveals that mice use a generalizable, albeit suboptimal, perceptual readout strategy of summing all V1 activity to detect stimuli.

🚨 This MUST READ essay and call to action spells out, in very clear terms, how the Trump administration could get away with slashing the NIH budget. NIH scientists and Dems in congress need to read and understand it. This is where we win or lose the battle to save the NIH and US science. 🧪 🧠 🧬 🔊

fantastic post, and tasty food for thoughts.

shamelessly adding here that many different types of STDP come about from minimizing a prediction of the future loss function with spikes :)

hopefully another case of successful predictions.

Proud of our new paper, such an interesting story! NonREM sleep is typically considered a "synchronized state", but we find many pairs of neurons are actively de-synchronized in nonREM and even more so with more delta activity.

Desynchronization Increased in the Synchronized State: Subsets of Neocortical Neurons Become Strongly Anticorrelated during NonREM Sleep

We aimed to better understand the dynamics of cortical neurons during nonREM sleep—a state in which neuronal populations are silenced for ∼100 ms of every second due to delta wave fluctuations. This a...
