Two routes to value-based decisions in Parkinsons disease: differentiating incremental reinforcement learning from episodic memory

Posted by dbos Columbia

Kavli Affiliate: Daphna Shohamy | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Patients with Parkinsons disease are impaired at incremental reward-based learning. It is typically assumed that this impairment reflects a loss of striatal dopamine. However, many open questions remain about the nature of reward-based learning deficits in Parkinsons. Recent studies […]

Dark exposure reduces high-frequency hearing loss in C57BL/6J mice

Posted by dbos Hopkins

Kavli Affiliate: Hey-Kyoung Lee and Patrick Kanold | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Plastic changes in the brain are primarily limited to early postnatal periods. Recovery of adult brain plasticity is critical for the effective development of therapies. A brief (1-2 week) duration of visual deprivation (dark exposure, DE) […]

Gravothermal Catastrophe in Resonant Self-interacting Dark Matter Models

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Daniel Gilman, Mark Vogelsberger, Xuejian Shen, Stephanie O’Neil | Summary: We investigate a self-interacting dark matter (SIDM) model featuring a velocity-dependent cross section with an order-of-magnitude resonant enhancement of the cross section at $sim 16,{rm km},{rm s}^{-1}$. To understand the implications for the structure of […]
