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 electrophysiological recordings in pigeons, simultaneously targeting three forebrain structures in the avian tectofugal visual system: the entopallium, intermediate nidopallium, and mesopallium ventrolaterale (MVL). Our preliminary results indicate that the ascending flow of information aligns with the anatomical organization reported in earlier studies. We decoded the timing of input arrival to these structures through current-source density analysis and revealed the transmission direction throughout the mentioned areas. Additionally, we observed that the previously reported simultaneous oscillatory bursts at the early stages of the tectofugal system end at the entopallium level, as MVL exhibits distinctively complex-spiking activity. These findings suggest that local computations in the entopallium differ from those in MVL. Current experiments investigate the fine-grained functional connectivity within and between these areas to find convergent or divergent computational properties.
