Population Dynamics in Neural Systems

1pm (via zoom)



The ability to simultaneously record the activity from tens to thousands and tens of thousands of neurons has allowed us to analyze the computational role of population activity as opposed to single neuron activity.  Recent work on a variety of cortical areas suggests that neural function may be built on the activation of population-wide activity patterns, the neural modes, rather than on the independent modulation of individual neural activity. These neural modes, the dominant covariation patterns within the neural population, define a low dimensional neural manifold that captures most of the variance in the recorded neural activity. We refer to the time-dependent activation of the neural modes as their latent dynamics, and argue that latent cortical dynamics within the manifold are the fundamental and stable building blocks of neural population activity.

Circadian Disruption and Schizophrenia

2pm (via zoom)



Schizophrenia is a multifactorial disease caused by an interaction between genetic variations and exposure to environmental insults. About 80% of individuals with schizophrenia show disrupted sleep and circadian rhythms. As a first step to understanding why schizophrenia is associated with such circadian disturbances, we have studied locomotor activity rhythms in two mouse models currently used to study the neurobiological bases of this disease: 1) the Sandy mice, which bear a mutation of the schizophrenia risk gene Dtnbp1, and 2) offspring from mouse dams that have undergone maternal immune activation (MIA). In both models, altered locomotor activity rhythms in running wheels have been noted, similar to abnormal rhythms observed in patients with schizophrenia. Our work highlights circadian disruption as a core pathophysiological component of schizophrenia, as both an integral symptom of the disease, and a likely risk factor for its development.



3pm-4:30pm Undergraduate/Postdoc poster session featuring:

Valentin Begel, Christina Vanden Bosch der Nederlanden, Jimmy Hernandez, Daria Lissus, Ella Sahlas, Sophia Stegeman, Michelle Wang, Margot Button, Mathilde Rioux
