MonkeyLogic Interface - SfS - Liquid dispenser - Precision Timer - Photo Detector

Specialized electronic hardware is essential for behavioral neurophysiology. The following links provide to detailed information about useful equipment for research.

MonkeyLogic is a behavioral control and data acquisition software system that runs on a PC under Matlab(tm). It was developed outside the NIH. However, we have developed an interface box.

MonkeyLogic Hardware Interface
Detailed schematics and mechanical layout for interfacing National InstrumentTM cards to BNC and D-subminiature connectors for easy connection to other apparatus.

The Stimulation and fMRI Synchronizer (SfS) tracks the scan cycle timing of a fast scan cyclic voltammetry (FSCV) recording system and provides stimulation and fMRI triggering output signals.

We have developed a Precision Liquid Dispenser for accurate and repeatable computer-controlled delivery of water and thicker fluids.

The Precision Timer for NIMH Cortex is a circuit board with software (firmware) for generating precisely timed pulses. NIMH Cortex is a data collection system. This hardware provides high precision timing (20 µs resolution) for NIMH Cortex.

We have developed a Photodetector Circuit to indicate the precise moment an image appears on the display screen of any behavioral control program.

We have adapted infrared (IR) proximity switches to replace mechanical switches for behavioral experiments. Here are some photos of the switches and parts information.

Non-Contact "Touch" Switch

We have developed a Smart Solenoid Driver to provide power for 24 volt solenoids typically used in juice reward applications.
