5+ day, 22+ hour ago   (726+ words) The Transmitter Neuromechanical models deepen our understanding of animal motor control Thanks to recent progress in physics-based simulators and robotics, it has never been easier for neuroscientists to use neuromechanical modeling to test hypotheses about animal movement. The renowned physicist…...

1+ week, 4+ day ago   (946+ words) thetransmitter.org Placing too much emphasis on a specific interpretation of dimensionality, or treating it as an end-all quantification of some aspect of neural computation, may hinder progress in understanding the brain. The following statement should be uncontroversial for any…...

1+ week, 5+ day ago   (106+ words) The Transmitter When we sleep, our brain is filled with spontaneous neural activity. What is it doing? Daniel Levenstein explains how internally generated brain activity during sleep shapes our cognition, and why NeuroAI is such a powerful approach to understanding…...

1+ week, 6+ day ago   (340+ words) THIS ARTICLE IS PART OF OUR STATE OF NEUROSCIENCE IN LATIN AMERICA REPORT. A 1992 PNAS paper showed how birdsong upregulates the expression of an immediate early gene in bird forebrains. The work revealed to Ribeiro the importance of studying molecular…...

4+ week, 2+ day ago   (260+ words) Mice seek information for curiosity’s sake—and their desire for knowledge versus a payout is represented distinctly in the brain, new findings suggest. “All men by nature desire to know” is the first line of Aristotle’s work “Metaphysics.” New findings…...

2+ week, 6+ day ago   (101+ words) The Transmitter How energy determines where proteins are produced in neurons Tatjana Tchumatchenko explains how mathematical modeling elucidates whether ion-channel proteins are produced locally in the soma or in the dendrites. In this episode of “Theoretical Neuroscience,” Gaute Einevoll talks…...

3+ week, 3+ day ago   (421+ words) Five years after a groundbreaking paper, can a young field move beyond piecemeal studies? From late 2013 to early 2016, a mass of ocean water up to 3 degrees Celsius warmer than average pulsed across the North Pacific Ocean. It was one of…...

3+ week, 5+ day ago   (475+ words) A study of developing human brain tissue suggests that genes switch on more strongly when they move from the nucleus’s edge toward structures that contain proteins involved in making and processing RNA. As neural stem cells mature into neurons, developmental…...

3+ week, 5+ day ago   (321+ words) The cultured spheres typically mimic only prenatal development, but the five-year-old ones grown in Paola Arlotta’s lab acquired postnatal features. Organoids typically model only pre- and perinatal brains and notoriously lack robust electrical activity, says In-Hyun Park, associate professor of…...
