In striking contrast, it showed a marked increase in discharge during execution up to a peak of 90 spikes/s: it reversed its pattern of activity as the task changed from observation to execution.
The database structures and interfaces used for discharge description and execution have to reflect this continuous mode of operation.
Mirror neurons discharge during both execution and observation of an action [14], [15].
The three early papers [1,2,18] provided details about the relative selectivity of mirror neuron discharge during action execution and observation.
To understand this, we recorded from identified corticospinal neurons in M1 and showed that, although many of these neurons exhibit mirror-like activity, there were major differences in their pattern and extent of discharge during action execution versus action observation.
These findings parallel experimental results in monkeys, demonstrating that same ventral premotor neurons, called mirror neurons, discharge both during the execution of an action and during the observation of a similar action performed by another individual [22].
In a botched execution the firing squad discharged their weapons at too long a distance so that the condemned men were not killed instantly.
[ 3], increasing their discharge during both observation and execution.
This distinguishes mirror neurons from other 'motor' or 'sensory' neurons whose discharge is associated with either execution or observation, but not both.
"Once he has received that information," the judges wrote, "the injunction shall be discharged without more and the execution may proceed".
Execution-related cells discharge on movement onset, while signal-related cells show anticipatory activity prior to the start of movement.
