2015 Zebrafish course at the Marine Biological Laboratory

It's been almost a week now that I am back from "fish camp", or, officially,¬†the "Zebrafish Development and Genetics" course at the Marine Biological Laboratory in Woods Hole. The various summer courses at the MBL are the stuff of legend, for various reasons. So what does a day in fish camp look like? If you're … Continue reading 2015 Zebrafish course at the Marine Biological Laboratory

New Study: Wireless Synchronization of Neurons?

My colleagues Greg Stacey - ResearchGate Profile, Tom Quail - ResearchGate Profile, and myself have published a new article in the Journal of Neurophysiology, "Computational Study of Synchrony in Fields and Microclusters of Ephaptically Coupled Neurons". Intrigued by a small set of previous works hinting at electric field-medited coupling between pairs of extremely close neurons, … Continue reading New Study: Wireless Synchronization of Neurons?

Motile fraction and actin velocity in in vitro motility assays

In this post, I discuss different quantities that can be extracted from in vitro motility assay velocity distributions. I explain¬†how the average velocity, the continuous sliding velocity, and the motile fraction relate to each other. There are two examples how these quantities change for different experimental effects in the motility assay. I close discussing different … Continue reading Motile fraction and actin velocity in in vitro motility assays

1-way ANOVA and Multiple Comparison Example in MatLab

Title says it all... Here is roughly what happens in the code below: We specify the sample size of the example groups we want to create. We create normally distributed sets of samples for each group with equal standard deviation. We sort the samples' values into vectors that can be used by the MatLab ANOVA … Continue reading 1-way ANOVA and Multiple Comparison Example in MatLab

Functional Clustering [CAMBAM Comp Neurosci Online Talk]

Detecting synchrony in neuron populations is an important task - often from the perspective of epilepsy and its origins. Several other neurological disorders are linked to hyper- and hyposynchrony, as well. Mostly synchrony is assessed over a whole population of neurons. The z statistic is frequently used to quantify synchrony, especially when thinking of neurons … Continue reading Functional Clustering [CAMBAM Comp Neurosci Online Talk]

Simple Example of Gillespie Algorithm in MatLab

Here is another simple example of the implementation of a Gillespie algorithm in MatLab. It is again for the students of our course "Topics in the Physical Basis of Physiology". I can highly recommend the course, it is one of the few that successfully combines "real" Physiology and Biology (not just toy models) and "real" … Continue reading Simple Example of Gillespie Algorithm in MatLab
