Open Source Technologies: From the virtual classroom

  Students in the Computational Methods course in the Neuroscience major at American University learn about core methods for open source science each fall. In past years, we have focused on learning Python for data analysis, methods for 3D printing, and using Arduino to build simple experimental rigs and run experiments. With the pandemic, it […]

Add machine vision to Arduino with OpenMV!

[et_pb_section][et_pb_row][et_pb_column type=”4_4″][et_pb_text] We have covered developments with the OpenMV project before on OpenBehavior, and they’ve just added a new feature that will be of interest to many behavioral neuroscientists. The OpenMV camera is a machine-vision camera that is programmed in Python.  The developers (Kwabena W. Agyeman and Ibrahim Abdelkader) have implemented many machine vision algorithms […]

An Open Source Syringe Pump Controller for Fluid Delivery of Multiple Volumes

August 20, 2020 Linda Amarante and colleagues from American University have developed and shared an open-source syringe pump controller for dispensing precise volumes of fluid over precise timescales. Delivering rewards are a crucial part of behavioral neuroscience experiments. In the case of liquid rewards, such as water, juice, chocolate milk or sucrose solutions, syringe pumps […]

An Open Source Automated Bar Test for Measuring Catalepsy in Rats

August 6, 2020 Researchers at the University of Guelph have created a low-cost automated apparatus for measuring catalepsy that increases measurement accuracy and reduces observer bias. Catalepsy is a measure of muscular rigidity that can result from several factors including Parkinson’s disease, or pharmacological exposure to antipsychotics or cannabis. Catalepsy bar tests are widely used […]

DeepFly3D, a deep learning-based approach for 3D limb and appendage tracking in tethered, adult Drosophila

July 23, 2020 Semih Günel and colleagues have created a deep learning-based pose estimator for studying how neural circuits control limbed behaviors in tethered Drosophila. Appendage tracking is an important behavioral measure in motor circuit research. Up until now, algorithms for accurate 3D pose estimation in small animals such as Drosophila did not exist. Rather, […]

BonVision

July 16, 2020 In a recent bioRxiv preprint, Gonçalo Lopes and colleagues from NeuroGEARS and University College London have shared information about BonVision — an open source software for creating and controlling visual environments. With advances in computer gaming and software rendering, it is now possible to create realistic virtual environments. These virtual environments, which […]
