DIY-NAMIC

September 10, 2020 Katherine Nautiyal from Dartmouth College has kindly shared the following about DIY-NAMIC, a high-throughput method to measure complex phenotypes in the homecage. ‘Operant behavioral paradigms provide rich data sets which are very useful for assessing manipulations in rodents models for neuropsychiatric disorders. However, the behavioral testing generally requires daily training for many […]

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 […]

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 […]

Rodent Arena Tracker (RAT)

June 18, 2020 Jonathan Krynitsky and colleagues from the Kravitz lab at Washington University have constructed and shared RAT, a closed loop system for machine vision rodent tracking and task control. The Rodent Arena Tracker, or RAT, is a low cost wireless position tracker for automatically tracking mice in high contrast arenas. The device can […]

Visual stimulator with customizable light spectra

May 7, 2020 Katrin Franke, Andre Maia Chagas and colleagues have developed and shared a spatial visual stimulator with an arbitrary-spectrum of light for visual neuroscientists. Vision research, quite obviously, relies on control of visual stimuli in an experiment. There are a great number of commercially available devices and hardware that are implemented in presenting […]

3DOC: 3D Operant Conditioning

April 23, 2020 Raffaele Mazziotti from the Istituto di Neuroscienze CNR di Pisa has generously shared the following about 3DOC, a recently developed and published project from their team. “Operant conditioning is a classical paradigm and a standard technique used in experimental psychology in which animals learn to perform an action in order to achieve […]
