The Database for Reaching Experiments and Models (DREAM) is a collaborative database that contains experimental data and models acquired through research from the field of computational neuroscience.  

== Where to Download ==

The database can be downloaded from http://crcns.org/data-sets/movements/dream/


== Welcome Information ==

Our friends at [http://crcns.org/data-sets/movements/dream/welcome-to-dream CRCNS] have graciously allowed us to keep our data on their site.  If you'd like to download models, tools, or experimental data, go to our page on their website

This entire page is a wiki.  As such, we welcome anyone to edit it, make suggestions etc. <br>

==How DREAM will help==

The general question of how people and animals move and learn to do so is one of the most challenging questions in neuroscience, biomechanics, computer science, statistics and psychology. Scientists within the reaching community study voluntary reaching movements made by humans and non-human primates. Many topics such as learning and adaptation, the role of the biomechanics in the control of movement, and sensory integration are studied by the reaching community and applied towards clinically relevant goals. The goals of these reaching studies are to uncover fundamental principles at the system level, to identify the underlying neural substrate(s) and to find clinically relevant tests and interventions. We believe that our database project will significantly accelerate progress toward these goals, as it benefits the modeling, physiological, clinical, behavioral, and experiment-focused communities that focus on reaching.

For the modeling community a broad database facilitates testing a model against multiple datasets and offers a unique benchmark for testing new models against both experimental data and current theories. For the electrophysiological community the database facilitates the search for links between motor behavior and its neural underpinning.  For the clinical community the database provides benchmarks to compare patients to. For the behavioral community such a database facilitates the identification of unknown and unanswered empirical questions. For experimentalists, this database will facilitate disproving models and designing experiments that efficiently distinguish between models. 

Also, the availability of the results of experiments and models will make it easier for scientists working in other fields, say, computational sciences, to model movement, thus lowering the barrier to entry for scientists from outside of the community. Their entry into the reaching community will also be facilitated by the [[workshops]], [[Summer School]] and [[competitions]] planned to take place in upcoming years. Also, wide areas of medicine, cognitive science, and computer science may expect to benefit from this project. Indeed, movement related research is of high medical and practical importance for movement rehabilitation.

==Why DREAM is needed==

The DREAM project will benefit from the tight integration of modeling and experimentation that is a hallmark feature of the reaching community. However the community is unfortunately somewhat divided between groups favoring different paradigms, focusing on equilibrium point control, internal models, uncontrolled manifolds, dynamical systems, or probabilistic approaches. We believe that this database will simplify the comparison of approaches and facilitate their synthesis into new approaches. 

It can be argued that a good model should ideally explain data from several labs and that a good experiment should not try to falsify a single model, but should ideally strive to falsify a good number of them. Indeed, over the last couple of years several labs have introduced models of motor control and motor adaptation and learning that explain multiple data sets from several labs (e.g. Flash and Hogan, 1985; Harris and Wolpert, 1998; Smith et al., 2006; Kording et al., 2007).  Our goal is to provide the opportunity for many people in the field to challenge current ideas and uncover new ones as we continue to seek models of movement that are increasingly accurate.

== How do I use or get involved with DREAM? ==

We need both users and content providers.  We sincerely expect most people to be both.  We'd love to help our database grow, so if you would like to [[share models and data | share your models or data]] with us, please do so!  But we also want this project to be accessible to many people.  For those with limited access to lab time and/or equipment, DREAM could provide a way to make meaningful contributions to the field by doing data analysis.  

== What the DREAM project will involve ==

We are developing a joint database designed so that many potential models of reaching can be appraised with multiple experimental datasets.  Our aim is to serve every interested experimental or modeling lab. We need the help of the scientists, researchers, students, subjects, and labs involved with reaching research.  If you are interested, please [[share models and data]] with us!

This project also focuses on activities aimed at making this joint database maximally useful: [[workshops]], [[Summer School]] and [[competitions]] will happen in the near future.

==Current status==

Right now, we're working to increase the amount of data sets we have to offer.  We also welcome anyone to reach out to us if they would like to run their models against our current sets.

==Future==

Along with continually seeking to add new data and models to our database, we are always looking for ways to improve our database.  Please share your [[ideas]] with us. Let us know if you have any questions, comments, or "Eureka!" moments that could help us better serve the reaching community.

<!-- ===2012===
:In 2012 we will hold a workshop where the wide community will be invited. During this [[workshops]] we will discuss the progress of the database so far. We will present early results, progress, challenges and the format of [[competitions]]. During this workshop, discussions will also be had about which variables are important and how the database format can be improved. The contributed datasets will be shared with the community and we will encourage them to participate in an online forum. In this way, modelers can also ask for additional data (e.g. where was the head of the subjects) that may be necessary for some models.
-->
===2013===
:In 2013 we will be aim to broaden the scope of the project. It starts with a workshop and [[Summer School]] that will make it easier for new participants to join the effort. Progress and challenges will be discussed and addressed, as we seek to add datasets that are progressively dissimilar to previously added data. Specific emphasis will be on datasets that combine reaching movements with imaging or electrophysiological data.
