Granularity of thalamic head direction cells
Head direction signaling is fundamental for spatial orientation and navigation. The anterodorsal nucleus of the thalamus (ADn) contains a high density of head direction (HD) cells that process sensori...

What changes and what stays the same as you scale from single neurons up to local populations of neurons up to whole brains?

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level).

I need some help from the #neuroskyence Bluesky-verse. Anyone know the source of this ~quote from Walter J. Freeman Jr.: "the secrets of the brain are hidden by two of God’s own firewalls: neurobiology and non-linear dynamics". I read it yrs ago but can't seem to find my way back to the source.

At this point, you should be embarrassed if your outlet has done nothing over these tumultuous six months to get itself barred by the administration.

The Wall Street Journal is speaking truth to power, but you're still on good terms with these assholes? Yeah, be proud of that.

“Our results indicate that individual V1 neurons do not signal how the actual visual input deviates from the animal’s predictions, as postulated within the predictive coding framework”

Thrilling to see a major theory get tested!
Cooperative thalamocortical circuit mechanism for sensory prediction errors - Nature
Experiments in mice show that a cortico-thalamic circuit generates prediction-error signals in primary visual cortex that amplify visual input that deviates from animals’ expectations.

I honestly think we should have a screening system for who gets to have money and influence based on asking "what was Star Wars about?" and "who were the good guys?"
Yes, Peter Thiel is functionally illiterate. Here’s his attempt at summarising the Star Wars plot to Maureen Dowd in 2017:

🚨 New paper in Journal of Vision!
We show that scene affordances—what you can do in a space—shape how we perceive and categorize scenes. This shapes your similarity preferences, predicts your categorization false alarms, and even alters neural representations. 🧵👇
