I just visited the ESI SyNC 2024 conference on the topic of "Time in the brain". There, I interviewed Hugo Merchant, an electrophysiologist at UNAM in Juriquilla, Mexico. Hugo works with macaques, who can rhythmically tap their fingers synchronized to a visual or auditory beat. By studying macaque neural activity in dimensionality-reduced spaces, he wants to understand how the brain encodes different time intervals. For an overview of our conversation, see the timestamps below.
