Cognitive Experiments Models & Neuroscience Lab
Behavioral Experiments
|
CEMNL has 7 behavioral testing rooms, each with 3D ready
Asus monitors capable of refresh rates up to 144 Hz, nVidia
shuttle glasses for presenting different images to different eyes, and
response boxes for the collection of highly accurate response time data. This
setup allows us to not only run simple accuracy experiments, but also
reaction time experiments, psychophysics experiments with tight control of
display properties, and continual flash suppression experiments in which we
present a visual image to just one eye in such a way that participants are
not aware that anything has been presented. |
Computational Models
|
All postdocs and graduate students in CEMNL are issued a
high speed multicore workstation for running computer simulations of
mathematical and neural network models. These models are coded using Matlab, R, or in some cases low-level computer languages
such as C++. These models explain and predict behavioral accuracy and
reaction time measures, neural measures such as EEG/ERP and fMRI, and in some
cases we build models that directly relate neural measures to behavioral
measures. In the event that a high-speed work station is insufficient for
these analyses, we have access to a state of the art server in the adjoining cMAP lab. |
Neuroscience Measures
|
CEMNL has an EEG lab, with a separate testing room and
control room. The EEG setup includes a 64 channel actiCHamp
amplifier and actiCAPs made by Brain Products. This
new technology combines the signal-to-noise advantages of active electrodes
with the ease of use provided by LED lights on each electrode for measuring
electrical impedances. The monitor for this setup is the same 3D ready ASUS
monitor as used in the behavioral testing rooms, allowing the collection of
steady-state visual evoked potentials. This lab is run through CEMNL but we
welcome other UMass researchers to use this resource. |
