A rhesus monkey was trained to move its arm in a direction that was perpendicular to and counterclockwise from the direction of a target light that changed in position from trial to trial. Solution of this problem was hypothesized to involve the creation and mental rotation of an imagined movement vector from the direction of the light to the direction of the movement. This hypothesis was tested directly by recording the activity of cells in the motor cortex during performance of the task and… Expand
An alternative interpretation of population vector rotation in macaque motor cortex
TLDR
It is proposed that results A and B are also consistent with an alternate hypothesis of 'response substitution', given four well known features of cortical neurophysiology. Expand
Direct cortical representation of drawing.
TLDR
A population vector method was used to visualize the motor cortical representation of the hand's trajectory made by rhesus monkeys as they drew spirals and showed that the movement trajectory is an important determinant of motor cortical activity. Expand
Cognitive spatial-motor processes
TLDR
Study of activity of 123 cells in the arm area of the motor cortex of three rhesus monkeys while the animals performed a 2-D step-tracking task with or without a delay interposed between a directional cue and a movement triggering signal revealed that the population vector during the delay period pointed in the direction of movement that was to be made later. Expand
Motor cortical activity in a context-recall task.
TLDR
These findings identify the neural correlates of a switching process that is different from a mental rotation described previously, and was evident both in the activity of single cells and in the time-varying neuronal population vector. Expand
Population-Vector Analysis by Primate Prefrontal Neuron Activities
TLDR
Results indicate that visual-to-motor transformation occurs during the delay period and that this process can be visualized by the population-vectoranalysis. Expand
Saccades to mentally rotated targets
TLDR
Saccadic latency increased linearly with the amount of directional transformation imposed between the stimulus and the response, indicating that mental rotation is a rather general mechanism through which directional transformations are achieved. Expand

TLDR
Analysis of the activity of single cells and neuronal populations in the motor cortex of behaving monkeys performing in the same tasks provided direct insight into the neural mechanisms involved and confirmed their different nature. Expand
Positive Feedback in the Cerebro-Cerebellar Recurrent Network May Explain Rotation of Population Vectors
TLDR
It is demonstrated that networks driven by positive feedback can account for the rotation of the direction vector observed in the motor cortex during reaching. Expand
Dynamic remapping
TLDR
This review summarizes the results from several physiological studies in which it has been possible to characterize the responses of neurons involved in temporal and spatial remappings and describes the types of cortical representations typically encountered in dynamic remapping. Expand
Population vector analysis of primate prefrontal activity during spatial working memory.
TLDR
Results indicate that spatial information represented by a population of prefrontal activity can be shown as the direction of the population vector and that its temporal change during spatial working memory tasks can be depicted as the temporal change of the vector's direction. Expand

Neuronal population coding of movement direction.
TLDR
The direction of movement was found to be uniquely predicted by the action of a population of motor cortical neurons that can be monitored during various tasks, and similar measures in other neuronal populations could be of heuristic value where there is a neural representation of variables with vectorial attributes.

Primate motor cortex and free arm movements to visual targets in three- dimensional space. II. Coding of the direction of movement by a neuronal population
We describe a code by which a population of motor cortical neurons could determine uniquely the direction of reaching movements in three- dimensional space. The population consisted of 475Expand
On the relations between the direction of two-dimensional arm movements and cell discharge in primate motor cortex
TLDR
The orderly variation of cell discharge with the direction of movement and the fact that cells related to only one of the eight directions of movement tested were rarely observed indicate that movements in a particular direction are not subserved by motor cortical cells uniquely related to that movement.
