Topic: oscillatory bursts

Slower (e.g., beta) and faster (e.g., gamma) oscillatory bursts have been linked to multiplexed communication between neural populations in different directions [1], respectively relaying, in a predictive coding interpretation, top-down expectations and bottom-up prediction error signals [2], which target and originate from distinct cortical layers with different dominant frequencies [3]. However, this oscillatory-multiplexed routing theory presents several challenges. Multiplexed routing might occur indeed without need for distinct frequencies of operation [4]. Furthermore, phasic enhancement

Mammals evolved a highly structured neocortex, composed of six cellular layers that are organized in functional columns. At first sight, the avian forebrain lacks a structured neocortex. However, the microstructural level of the avian sensory forebrain exhibits remarkable anatomical similarities to the mammalian brain organization. This study focuses on investigating the functional properties of three avian visual forebrain structures, to determine whether both taxa share a common functional neural circuitry, despite apparent anatomical differences. We conducted multi-channel electrophysiologi
