Construction And Assembly Of A Hyperdrive Recording Implant, Andrew A. Ortiz, Ryan A. Wirt, James M. Hyman

AANAPISI Poster Presentations

The ability to record neural activity from multiple brain areas is crucial for the understanding of how different areas of the brain function or interact. This poster will cover instructions on how to construct and assemble a hyperdrive recording implant that bilaterally targets the ACC and the hippocampus. Intriguingly, the design of the hyperdrive recording implant is flexible and can be constructed to target other brain areas. The implant consists of 32 twisted bundles of tetrodes with a total of 128 individual recording wires which are controlled by movable ‘drivers’ (Gray et al., 1995; McNaughton et al., 1983). All 128 …

• Dancing to music is a human universal that relies on beat perception.
• Listeners may infer the “tempo” or speed of music from:
• the time interval between beats;
• the density of events;
• higher-level features of musical temporal organization (the meter).
• The “Gabbling Foreigner Illusion” is the observation that listeners perceive unfamiliar languages as being faster than familiar ones.
• Even when music is the same speed, listeners tap faster to unfamiliar music.
• Does culture background impact how we perceive musical tempo?
