Introduction - overview of sensory-motor control

Aug 4-5
Lecturers: Gunnar Blohm, Kurt Thoroughman

DREAM database - Introduction to the data and model sharing initiative

Aug 4 (evening)

Lecturer: Gunnar Blohm

The DREAM project should be on the USB drives of a few different students. If you haven't yet, find someone who has the data and get it from them. DREAM can also be downloaded piece-wise (data sets, models, tools, and documentation) from CRCNS: http://crcns.org/data-sets/movements/dream/downloading-dream. You will need to create an account on CRCNS to be able to download the project files. If you want "all" of DREAM (models, tools, and documentation), click here: AllDream.zip

If you're familiar with svn and would like info/credentials for code in the repository, contact Ben Walker

Update: Here's the fixed version of LoadDreamPaths.m. (The originally distributed version had Windows directory formatting using '/' and would not work for *nix. This script should work for all OSes.)

Here is a description of data sets currently in Dream. Dream is growing, but this list is accurate as of the time of the summer school (click on the link to access the related publication).

• Burns -- reaching with head tilt and left/right visual perturbations
  
• Corbett -- reach trajectory predictions based on EMG and gaze movements
  
• Fernandes -- reaching with uncertain and rotated midpoint feedback
  
• Flint -- decoding of reaching movements from local field potentials
  
• Kording -- reaching with uncertain midpoint feedback
  
• Mattar 07 -- generalizing from one, two or multi targets to another direction
  
• Mattar 10 -- reaching to a distance (short/long), generalizing to the other one (long/short)
  
• Ostry -- move in force field, get an estimation of where the hand is
  
• Scott -- monkey (no spike), center out: even and not evenly distributed targets, also a forward/back
  
• Stevenson -- center out, monkey with neural time stamps
  
• Thoroughman -- reach adaptation to perturbations with different complexity
  
• Vahdat -- movement in force field with FMRI scans pre/post learning
  
• Wei 08 -- visual perturbations, cursor shown only at target
  
• Wei 10 -- movement in differing force fields
  
• Young -- movement time stayed the same, but distance changed; fast, medium, slow reaches.
