Dopamine and the need for alternative theories

Some experimental findings are inconsistent with the dominant model of reward prediction error, highlighting the need for alternative testable and falsifiable models for dopamine function.

Does a new theory of dopamine replace the classic model?

My answer would be no, but the model poses challenges that will sharpen our understanding of dopamine and learning.

Can an emerging field called ‘neural systems understanding’ explain the brain?

This mashup of neuroscience, artificial intelligence and even linguistics and philosophy of mind aims to crack the deep question of what "understanding" is, however un-brain-like its models may be.

Dancing in the dark: Honeybees use antennae to decode nestmates’ waggles

The insects align their antennae with their body’s angle to a dancer—information that vector-processing circuitry in the brain deciphers into a flight path, a new study suggests.

In hot water: Climate change tests limits of neuronal resilience in crabs

Warming seas disrupt the function of neurons — and could seed permanent changes in marine species, according to studies of a circuit that controls digestion in crustaceans.

What ‘drifting representations’ reveal about the brain

How neuronal activity patterns associated with a behavior can change, even when the behavior does not — something once seen as an experimental artifact — could offer new insights about neural function.

Rajesh Rao reflects on predictive brains, neural interfaces and the future of human intelligence

Twenty-five years ago, Rajesh Rao proposed a seminal theory of how brains could implement predictive coding for perception. His modern version zeroes in on actions.
