Human Strategy Adaptation in Reinforcement Learning Resembles Policy Gradient Ascent

Kavli Affiliate: Marcelo Mattar | Authors: Hua-Dong Xiong, Li Ji-An, Robert C Wilson and Marcelo G Mattar | Summary: A hallmark of intelligence is the ability to adapt behavior to changing environments, which requires adapting one’s own learning strategies. This phenomenon is known as learning to learn in cognitive science and meta-learning in artificial intelligence. […]

Sleep pressure is differentially regulated by molecularly distinct subtypes of Lhx6-positive and Lhx6-negative neurons of the zona incerta.

Kavli Affiliate: Seth Blackshaw | Authors: Parris Washington Chandler, Sang Soo Lee, Leighton Duncan, Dong Won Thomas Kim, Mark Wu and Seth Blackshaw | Summary: Sleep pressure, the accumulating drive towards sleep during wakefulness, is shaped by Lhx6-positive GABAergic neurons in the zona incerta (ZI). Here, we show that these neurons are broadly activated both […]

Heterogeneous responses to embryonic critical period perturbations within the Drosophila larval locomotor circuit.

Kavli Affiliate: Michael Miller | Authors: Niklas Krick, Jacob Davies, Bramwell Coulson, Daniel Sobrido-Camean, Michael Miller, Matthew C.W. Oswald, Aref Arzan Zarin, Richard Baines and Matthias Landgraf | Summary: As developing neural circuits become functional, they undergo a phase of heightened plasticity that facilitates network tuning in response to intrinsic and/or extrinsic stimuli. These developmental […]
