Dr. Abbott is the William Bloor Professor of Theoretical Neuroscience at Columbia University. He studies the brain using computational modelling and mathematical analysis of neurons and neural networks.

Talks by Larry Abbott

Lecture Series presented by KPMG - Sense from Chaos: Controlling the Dynamic Networks of the Brain

Larry Abbott Columbia University
Activity recorded from neurons in the brain often looks random or chaotic. How do we make sense of the world and produce precisely controlled responses when so much of the activity in our brains is chaotic? This talk will show how brain circuits can switch between chaotic and well-controlled patterns of activity, illustrating these points with computer demonstrations of network models. This talk will also discuss how chaotic activity may be useful for a healthy brain function and demonstrate what goes wrong when activity is insufficiently chaotic.

The Dynamics of Neural Networks

Larry Abbott Columbia University
Neural circuits exhibit complex patterns of spontaneous activity. I will discuss how neural network models can reproduce this activity and how it interacts with responses evoked by sensory stimuli. This work involves analytic, mean-field and computer analyses of large systems of nonlinear differential equations with random parameters.
