According to Schmidt, four things are stored in memory after an individual generates a movement: [6] The initial conditions of the movement, such as the proprioceptive information of the limbs and body. The response specifications for the motor programs, which are the parameters used in the generalized motor program, such as speed and force.
These difficulties have led to a more nuanced notion of motor programs known as generalized motor programs. [30]: 240–257 A generalized motor program is a program for a particular class of action, rather than a specific movement. This program is parameterized by the context of the environment and the current state of the organism.
Motor learning research often considers variables that contribute to motor program formation (i.e., underlying skilled motor behaviour), sensitivity of error-detection processes, [1] [2] and strength of movement schemas (see motor program). Motor learning is "relatively permanent", as the capability to respond appropriately is acquired and ...
For example, if, in addition to reaching with the arm, the hand must be controlled to grab an object, an efference copy of the arm motor command can be input into a forward model to estimate the arm's predicted trajectory. With this information, the controller can then generate the appropriate motor command telling the hand to grab the object.
The first two steps of the Gram–Schmidt process. In mathematics, particularly linear algebra and numerical analysis, the Gram–Schmidt process or Gram-Schmidt algorithm is a way of finding a set of two or more vectors that are perpendicular to each other.
For example, the CPG underlying the escape swim response in Tritonia diomedea contains intrinsic neuromodulatory neurons. These neuromodulatory neurons can enhance neurotransmitter release from another neuron in the circuit and its neuromodulatory actions are thought to be important for producing swim motor program.

A Schmidt coupling is a type of coupling designed to accommodate large radial displacement between two shafts. Consisting of an arrangement of links and discs—three discs rotating in unison, interconnected in series by three or more links between each pair of discs—a Schmidt coupling can adapt to very wide variations in radial displacement while running under load.
In neuroscience and motor control, the degrees of freedom problem or motor equivalence problem states that there are multiple ways for humans or animals to perform a movement in order to achieve the same goal. In other words, under normal circumstances, no simple one-to-one correspondence exists between a motor problem (or task) and a motor ...
