David Wang is a graduate students in the Liqun Luo lab. He will present his work on the embryonic neuronal activity in the development of cortical circuits.
Abstract: Neuronal activity is vital in shaping the architecture of neural circuits throughout development. Here we present the finding of an embryonically active population of neurons in the primary olfactory cortex, a region of high recurrent intracortical connectivity. Using in vitro slice and in vivo neuronal population recordings, we show that while these embryonically active neurons do not appear involved in neonatal olfaction, they possess hub-like properties that may play a key role in the dynamics of this developing cortical circuit.
