  Single Unit Laboratory  
 

 

The Brain Sciences Center's Single Unit Laboratory houses state-of-the-art hardware and software used in studies of electrical activity of the brain and basic research on cognitive function.

 

Bak™ Time and Amplitude Neural Discrimantors look at the analog signal and can produce different outputs for individual cells that are based on pre-set time/amplitude thresholds.

 

Alpha-Omega™ Discriminators display the outputs from seven different channels.  Each channel can perform 'template matching' for each of three different cells.  A template consists of six timepoints with adjustable 'time windows' that enable the researcher to establish the criteria for the identification of signal emanating from individual neurons.

 

A Thomas Recording Eckhorn™ Microelectrode manipulator can operate 32 electrodes at once.  The Eckhorn has pre-amps which send the signals from the electrodes to discriminating amps.  The 32 'stepper' motors in the Eckhorn are used to individually manipulate the electrodes, which we can manufacture in our lab.

 

Plexon™ software (familiarly known as the 'Harvey Box') is similar to the Alpha-Omega in that it amplifies and discriminates, with the added capability of working with recorded signals 'offline'.

 

An ISCAN™ video-based monitoring system keeps track of eye-position to ensure that eye movements do not interfere with the recording of neuronal signals.
