The Mathematics and Cognition, Joint with the Stochastic Modeling Seminar Series, will
present our next lecture on Tuesday, April 23, at 12:15 PM in GWC 604.
Our speaker will be Steve Baer of the Department of Mathematics,
who will speak on the topic:
"Noise Sensitivity in a Neuronal Burster: Can Small Amplitude Synaptic Noise Influence Activity-Dependent Morphological Plasticity of Dendritic Spines ?"
Abstract.
| Using a combination of asymptotic and numerical methods, I will investigate the effect of small noise on a neuronal burster of elliptic type (also called a type III or Hopf/Circle burster). The analysis will be applied to a stochastic model of an excitable spine, with an activity-dependent stem conductance, that exhibits conditional burst dynamics. The study suggests that small amplitude synaptic noise has the potential to significantly influence activity-dependent morphological plasticity of dendritic spines. |
