Last week we kicked off our first lab meeting of the new academic year. No scientific presentation this time. Instead, we were tasked with designing experiments to answer some *truly critical* research questions.

La nature compose-t-elle ses propres mélodies ? 🐦🎶

Existe-t-il des mélodies naturelles ?
De nombreuses cultures musicales choisissent des échelles établissant des rapports de fréquence simples (2:1, 3:2, 4:3) entre les notes.

Animals make errors influenced by both perceptual and non-perceptual factors. Last study from Jeffrey Boucher and Yves Boubenec from our lab uses this to show that premotor cortex tracks the perceived stimulus, not the one reported by behavior. Discover more: tinyurl.com #Neuroscience #fUSi
Premotor cortex hemodynamics reflect internal auditory category, not reported category
In sensory decision-making tasks, animals’ decisions are driven by perception, but also by non-perceptual factors. Because of external and internal noise, stimuli may be internally misclassified, lead...
