🧠 New landmark study “A #brain-wide map of #NeuralActivity during complex #behaviour” by the #InternationalBrainLaboratory (Angelaki et al., 2025): >600,000 #neurons across 279 regions in 139 mice, unified across 12 labs with #Neuropixels probes.

#DecisionMaking isn’t confined to single hubs but distributed across the brain, incl. #sensory, #motor & #reward areas, showing how #cognitive processes emerge from brain-wide #dynamics.

Wow. Clear, complete, engaging overview of the wondrous world of the brain, brainstem, and nerves. With plenty of insights into their fragility, too, from early development to complex emotional and cognitive phenomena. Why not five stars? A little note concerning invasive animal experiments. The professor made a good job presenting every topic with the utmost respect, also showing awareness of criticisms, and he made a little reference to animal welfare standards and regulations in his workplace. But I personally prefer paths towards the substitution of invasive animal tests. Anyway, in the framework of learning, it's important to know what others have done, even if you choose different paths. And the course offers an excellent foundation in medical neuroscience. Thank you, Professor White!

This is interesting. A consortium of 22 research labs in the EU & US has analysed how brains make decisions. To add a cuteness factor, they monitored mice as they played little computer games.

"A decision, it turns out, is not hatched in a single cortical enclave, but emerges from a grand orchestration of regions spread across the brain, including those once understood to be the preserve of movement rather than thought."

A "grand orchestration" sounds delicious. I'd love to see an animation of 600,000 neurons firing in waves.

Continued thread

You cannot improve when scared

"The more primitive parts of the brain take over the activity of the prefrontal cortex, the brain’s “control centre”, when we’re in a state of fear.
"This means planning, making sound decisions and using our existing knowledge becomes very difficult if we feel threatened or afraid."

Deborah Pino Pasternak: theconversation.com/how-effect

The ConversationHow effective is fear as a teaching tool? How and what do we learn when we are scared?In response to threats, we learn to avoid challenge and comply with external rules (instead of wondering how systems can be improved). We protect our feelings and restrict our thoughts to what’s safe.

Wow 🤩 For Some Patients, the ‘Inner Voice’ May Soon Be Audible

For decades, neuroengineers have dreamed of helping people who have been cut off from the world of language.

A disease like amyotrophic lateral sclerosis, or A.L.S., weakens the muscles in the airway. A stroke can kill neurons that normally relay commands for speaking.

Perhaps, by implanting electrodes, scientists could instead record the brain’s electric activity and translate that into spoken words
