 The study examined the similarities between rodents and primates in terms of their hippocampal oscillation patterns. It was found that while rodents have distinct theta and gamma oscillations, primates have a different pattern of oscillations, with theta and slow gamma being more prominent than gamma. Additionally, the study showed that beta2 and slow gamma are more prevalent during explorative behaviors in primates, while theta is not as present. This suggests that theta oscillations may be more important for other cognitive processes such as memory or decision making. This article was authored by Salman Abbaspour, Ahmed T. Hussin and Kari L.
