Neural Codes for Space, Time & Memory
In the Primate Hippocampus
​
The hippocampus's role in navigation has been highlighted by key neuroscience discoveries like place cells and grid cells over the past 50 years. However, most of this research has focused on rodents, resulting in limited understanding of space and time neural codes in the primate hippocampus, including humans.
The Social Primate Brain
​
Social animals must coordinate their behavior for reproduction and survival, relying on synchronization in space and time. This coordination is supported by neuronal mechanisms for social mapping. Traditionally, the hippocampus was thought to focus on self-navigation and cognitive mapping. However, recent research has revealed social place and time cells in the hippocampus, indicating its role in representing others in both dimensions. Our lab aims to understand the neural circuits in this process within the primate hippocampus.
The Mystery of Human Language
Evolution
The idea that human language emerged suddenly, like an "evolutionary big bang," from nonhuman primate vocal communication is beginning to change. Until recently, vocal communication in nonhuman primates was considered genetically determined and inflexible. However, new evidence is showing more flexibility in their vocal production and other aspects of their communication. We are using cutting-edge machine learning tools to uncover additional evidence that supports this bold new perspective.
Deciphering the Neural Codes for Territoriality
How does our brain combine spatial coding with social signals to understand a territory? Our aim is to explore how the hippocampus's neural spatial codes for ourselves and others are influenced by the neuromodulator oxytocin to shape territorial behavior.
