Task-specific neural processes underlying conflict resolution during cognitive control

Lab Results talk by Yuchen Xiao

Wed Jan 19th, 9:30am

Everyday decisions require integrating sensory cues and task demands while resolving conflict in goals and cues (e.g., “should I go for a run or stay home and watch a movie?”). The ability to exert cognitive control during decision-making plays a fundamental role in our daily activities, as demonstrated by the debilitating effects of malfunction in control networks. Predominant theories of cognitive control posit universal mechanisms of conflict resolution. The results of the current study challenge this dogma by demonstrating that the neural circuits involved in orchestrating cognitive control are specific to the combination of inputs and outputs in each task.

Neuro 140/240: Biological and Artificial Intelligence

Harvard, Spring 2022

Class starts on Tuesday Jan 25th, 2022, 3-5pm

Northwest Building B108

Link to class website

This is a seminar-style course which provides a foundational overview of key ideas in Computational Neuroscience and the study of Biological Intelligence. At the same time, the course will connect the study of brains to the blossoming and rapid development of ideas in Artificial Intelligence. Topics covered include the biophysics of computation, neural networks, machine learning, bayesian models, theory of learning, deep convolutional networks, generative adversarial networks, neural coding, control and dynamics of neural activity, applications to brain-machine interfaces, connectomics, among others. Lectures will be taught by leading Harvard experts in the field.

Building a Map of the Human Brain Functional Connections at the Mesoscale

PDF Wang J, Tao A, Anderson WS, Madsen JR, Kreiman G (2021). Mesoscopic physiological interactions in the human brain reveal small world properties. Cell Reports, 36 (8) 109585. Supplementary Material | Resources

Cognition relies on rapid and robust communication between brain areas. Wang et al. leverage multi-day intracranial field potential recordings to characterize the human mesoscopic functional interactome. They validated the methods using monkey anatomical and physiological data. The human interactome reveals small-world properties and is modulated by sleep versus awake state.
