Bespoke photometry system captures variety of dopamine signals in mice

The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

Illustrated portrait of Tim Ryan.

Timothy Ryan on his pivotal switch from studying particle physics to decoding synaptic transmission

Dissuaded from pursuing theoretical physics and deterred by the “long feedback loop” in experimental physics, the National Academy of Sciences member took inspiration from “polymath” Watt Webb and “visionary” Stephen Smith—and learned to work “completely outside his comfort zone.”

Book cover of The Brain, In Theory by Romain Brette.

‘The Brain, In Theory,’ an excerpt

In his new book, Brette pushes back against theories that describe the brain as a “biological computer.” In this excerpt from Chapter 4, he challenges equating brain evolution with programming, and the universality of neural network models.
