The CIM physical space runs the length of Moore Hall and is newly renovated to support state of the art interactive research. Our 1270 sq ft main meeting room with kitchen is flexibly designed to provide informal meeting and lounge space as well as host our larger talk and workshop series. This main room is further equipped with a central ceiling frame which supports cameras and sensors for large group and inter-group research.
Next to our meeting space is a shared testing facility with 1350 sq ft divided into seven testing rooms, waiting area, and administrative space. In this facility we run behavioral experiments, multi-person psychophysiology, eye-tracking and EEG/hyperEEG.
We have several Biopac MP150 systems equipped with Acknowledge software for recording electrodermal activity and photoplesmography simultaneously from interacting dyads in our behavioral lab, neuroimaging center, and epilepsy monitoring unit. The equipment interfaces with stimulus delivery computers using a low latency LabJack digital I/O interface.
We have four E4 wristbands developed by Empatica to perform real-time monitoring and recording of electrodermal activity, photoplesmography, peripheral temperature, and 3-axis accelerometers.
We have six mobile eye-trackers from Pupil labs capable of simultaneously recording binocular eye gaze and pupillometry at 200hz synchronized with an outward facing camera.
We have a Pathways integrated thermal stimulator from Medoc for delivering computer-controlled thermal stimulation capable of delivering heat up to 50 degrees C and cold down to -10 C in a computer-controlled fashion. Stimulation and recording equipment are electronically synchronized with experimental computers via wireless networking for integrated stimulus delivery and physiological monitoring. Parallel control software allows for the capability to dynamically program the thermal stimulator based on participant behavior (choices, eye position, etc.). This equipment can be used in the behavioral lab and neuroimaging center.
We have two FOMRI-III MRI compatible optical microphones with active noise-cancellation that make it possible to record intelligible speech from both participants during simultaneous fMRI scanning. Two sets of S14 MRI compatible earphones by Sensimetrics provide high-quality acoustic stimulus delivery while further attenuating scanner noise.Our multiple 32-channel EEG systems (BrainProducts) can be linked to provide hyperEEG between dyads.
We have six custom made headsets with GoPro Hero4 cameras that provide the ability to continuously record 1080p resolution at 120 frames per second while participants interact with each other. We also have two GoPro Max cameras capable of recording 360 degree views when small groups of participants are interacting.
We have 250 OpenBeacon active bluetooth tags for studying social interactions of large groups. The tags perform proximity monitoring and include 3D accelerometers for tracking movement.
We have an assortment of computing hardware to aid in the collection and analysis of data. In collaboration with the Dartmouth Brain Imaging Center and Research Computing, we currently have dedicated access to the Discovery higher performance computing cluster equipped with ten Dell PowerEdge R430 Nodes with twenty-four 2.6GHz cores, 96gb of RAM, and 10gig and InfiniBand connectivity and also a high RAM Hewlett Packard Enterprises DL560 Gen9 head node with forty 2.6Ghz computing cores and 1.5tb of RAM, and 10 gigabit network connectivity. In addition we have unlimited access to the centrally managed Dartmouth Discovery Cluster, which has 2600+ cores, 20 Tesla C2050 GPU boards, 8.5 TB of RAM, and 200+tb of storage space.
We have a high performance web server Microway NumberSmasher with 16 2.6GHz cores, 128gb of RAM, and 12tb of RAID6 SAS storage for hosting group experiments in the lab or online.
We have several high performance linux analysis workstations equipped with 96 AMD Threadripper CPU cores, 768gb of RAM, 136tb of RAID 5 storage, and 3 water cooled NVIDIA RTX 3090 GPUs.
