Neurocognitive aging is associated with distinct patterns of changes in task-related brain activities in the aging brain. However, the brain mechanisms underpinning such changes are …
Abstract of Aging Effects on Task-Evoked Pupillary Reponses, by Mingjian He, Degree ScM., Brown University, May 2018. Previous studies have found decreased cell counts and …
Biological brains are dynamic. Recent advances in electrophysiology and neuroimaging have helped uncover various mechanisms through which brains construct and utilize rich variations in neural …
In order to navigate a complex web of relationships, an individual must learn and represent the connections between people in a social network. However, the …
Humans are remarkably adept at generalizing knowledge between experiences in a way that can be difficult for computers. Often, this entails generalizing constituent pieces of …
How synaptic plasticity in-vivo manages diverse properties of biological neural networks remains poorly understood. My collaborators and I address this by examining basic models of …
In the current project, I examined how efficiently people learn social norms. Specifically, I investigated the relative learning efficiency for social norms by comparing it …
Perception of the 3D world is intuitive and effortless. The visual system is capable of processing the complexities in the retinal image to produce percepts …
The medial temporal lobe (MTL) plays important roles in humans and animal cognition, for example, in episodic memory and spatial navigation. In rodents, two prominent …
This thesis examines the cognitive consequences of sleep loss in the context of attention-deficit/hyperactivity disorder (ADHD) symptom severity in children. We used a wake extension …
How do humans learn to adaptively function in a fundamentally uncertain social world? Since we cannot directly observe the contents of other people’s minds, the …
