Topological data analysis of zebrafish patterns.
Proceedings of the National Academy of Sciences of the United States of America
Feb 25, 2020
Self-organized pattern behavior is ubiquitous throughout nature, from fish schooling to collective cell dynamics during organism development. Qualitatively these patterns display impressive consistency, yet variability inevitably exists within patter...
Robotic platform for microinjection into single cells in brain tissue.
EMBO reports
Aug 30, 2019
Microinjection into single cells in brain tissue is a powerful technique to study and manipulate neural stem cells. However, such microinjection requires expertise and is a low-throughput process. We developed the "Autoinjector", a robot that utilize...
Single-cell approaches to cell competition: High-throughput imaging, machine learning and simulations.
Seminars in cancer biology
May 18, 2019
Cell competition is a quality control mechanism in tissues that results in the elimination of less fit cells. Over the past decade, the phenomenon of cell competition has been identified in many physiological and pathological contexts, driven either ...
Joint reconstruction and classification of tumor cells and cell interactions in melanoma tissue sections with synthesized training data.
International journal of computer assisted radiology and surgery
Feb 16, 2019
PURPOSE: Cancers are almost always diagnosed by morphologic features in tissue sections. In this context, machine learning tools provide new opportunities to describe tumor immune cell interactions within the tumor microenvironment and thus provide p...
Extracellular GABA assisting in organizing dynamic cell assemblies to shorten reaction time to sensory stimulation.
Biological cybernetics
Feb 12, 2019
Until recently, glia, which exceeds the number of neurons, was considered to only have supportive roles in the central nervous system, providing homeostatic controls and metabolic supports. However, recent studies suggest that glia interacts with neu...
The role of neuron-glia interactions in the emergence of ultra-slow oscillations.
Biological cybernetics
Nov 11, 2017
Ultra-slow cortical oscillatory activity of 1-100 mHz has been recorded in human by electroencephalography and in dissociated cultures of cortical rat neurons, but the underlying mechanisms remain to be elucidated. This study presents a computational...
Nano-topography Enhances Communication in Neural Cells Networks.
Scientific reports
Aug 29, 2017
Neural cells are the smallest building blocks of the central and peripheral nervous systems. Information in neural networks and cell-substrate interactions have been heretofore studied separately. Understanding whether surface nano-topography can dir...
ARACHNE: A neural-neuroglial network builder with remotely controlled parallel computing.
PLoS computational biology
Mar 31, 2017
Creating and running realistic models of neural networks has hitherto been a task for computing professionals rather than experimental neuroscientists. This is mainly because such networks usually engage substantial computational resources, the handl...
Knowledge-Based Analysis for Detecting Key Signaling Events from Time-Series Phosphoproteomics Data.
PLoS computational biology
Aug 7, 2015
Cell signaling underlies transcription/epigenetic control of a vast majority of cell-fate decisions. A key goal in cell signaling studies is to identify the set of kinases that underlie key signaling events. In a typical phosphoproteomics study, phos...
Simple Algorithms for Distributed Leader Election in Anonymous Synchronous Rings and Complete Networks Inspired by Neural Development in Fruit Flies.
International journal of neural systems
May 26, 2015
Leader election in anonymous rings and complete networks is a very practical problem in distributed computing. Previous algorithms for this problem are generally designed for a classical message passing model where complex messages are exchanged. How...
