Although individual neurons in the arm area of the primate motor cortex are only broadly tuned to a particular direction in three-dimensional space, the animal can very precisely control the movement of its arm. The direction of movement was found to be uniquely predicted by the action of a population of motor cortical neurons. When individual cells were represented as vectors that make weighted contributions along the axis of their preferred direction (according to changes in their activity… Expand

Topics from this paper

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
Where Does the Population Vector of Motor Cortical Cells Point during Reaching Movements?
TLDR
The results suggest the NPV does not give a faithful image of cortical processing during arm reaching movements and may even fail to reflect the parameters of movement when arm posture is changed. Expand
Mental rotation of the neuronal population vector.
TLDR
Results provide direct, neural evidence for the mental rotation hypothesis and indicate that the neuronal population vector is a useful tool for "reading out" and identifying cognitive operations of neuronal ensembles. Expand
Shift of preferred directions of premotor cortical cells with arm movements performed across the workspace
TLDR
The results suggest that the cortical areas studied represent arm movement direction within a coordinate system rotating with the arm and where signals about the movement direction relate to the motor plan through a simple invariant relationship, that between cell preferred direction and arm orientation in space.

Reaching to Visual Targets: Coordinate Systems Representation in Premotor and Motor Cortices
Individual arm-related neurons in both motor (area 4) and premotor (area 6) cortices of the monkey are directionally tuned. We studied these directional neurons while monkeys made arm movements ofExpand
Relationship between Unconstrained Arm Movements and Single-Neuron Firing in the Macaque Motor Cortex
The activity of single neurons in the monkey motor cortex was studied during semi-naturalistic, unstructured arm movements made spontaneously by the monkey and measured with a high resolutionExpand
Population coding of arm-movement-related neurons in and below the superior colliculus of Macaca mulatta
TLDR
It is shown that a subpopulation of this type of neuron is able to code for limb movement by the population vector and the cosine function cannot describe these neurons adequately, so the Fisher distribution yields a much better description of arm-movement-related cells in the superior colliculus. Expand
Population activity in the control of movement.
This chapter discusses the key observations and concepts concerned with the role of neuronal populations in the specification and control of the direction of movement and isometric force. The chapterExpand
Hypothetical joint-related coordinate systems in which populations of motor cortical neurons code direction of voluntary arm movements
  • Shoji Tanaka

TLDR
A set of joint-related coordinate systems that rotate with the posture of the arm in which populations of motor cortical neurons code direction of the hand movement in an intrinsic coordinate system is proposed. Expand
Dissociation between hand motion and population vectors from neural activity in motor cortex
TLDR
Recording the activity of neurons in contralateral MI of monkeys while they made reaching movements with their right arms oriented in the horizontal plane found systematic biases between the population vector and the direction of hand movement. Expand

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. Expand
Coding of information about rapid eye movements in the pontine reticular formation of alert monkeys
TLDR
The results suggest that a vector description is not only a convenient mathematical tool, but is the way eye movements are coded in the PRF and possibly elsewhere in the central nervous system. Expand
Functional properties of neurons in middle temporal visual area of the macaque monkey. I. Selectivity for stimulus direction, speed, and orientation.
TLDR
The presence of both direction and speed selectivity in MT of the macaque suggests that this area is more specialized for the analysis of visual motion than has been previously recognized. Expand
Relations between parameters of step-tracking movements and single cell discharge in the globus pallidus and subthalamic nucleus of the behaving monkey
TLDR
The results of these studies suggest that cells in GPe, GPi, and STN may be involved in the control of movement parameters. Expand
Body position with respect to the head or body position in space is coded by lumbar interneurons.
TLDR
It is suggested that neck responses originate in receptors, probably spindles, in perivertebral muscles presumably is best stretched by a particular direction of pull, which seems likely that convergence from receptors in selected muscles determines the direction of a spinal neuron's vector. Expand
Responses to head tilt in cat central vestibular neurons. I. Direction of maximum sensitivity.
TLDR
The broad distribution of response vector orientations provides an appropriate substrate for vestibulospinal reflexes to a wide variety of head tilts, similar to previously reported tin utricular afferents. Expand

TLDR
The results suggest that intracollicular microstimulation, with stimuli commonly used in studies of electrically evoked saccades, is accompanied by widespread synaptic activation of the intermediate gray layer, and one possible form of such a distributed coding mechanism is discussed. Expand
Space-time representation in the brain. The cerebellum as a predictive space-time metric tensor
TLDR
The concept of space-time representation in the brain is redefined using tensor network theory and the cerebellum acts as a predictive motor space- time metric which allows the establishment of coincidences of goal-directed movements of limbs inspace-time with external targets. Expand
Tonic neck reflex of the decerebrate cat: response of spinal interneurons to natural stimulation of neck and vestibular receptors.
TLDR
Combined neck and vestibular stimulation indicated that the dynamic behavior of neurons was determined by a linear summation of the responses to these stimuli, similar to the neckforelimb reflex evoked in unparalyzed intact-labyrinth and labyrinthectomized cats. Expand
