Summary of "Why Are Sequence Representations in Primary Motor Cortex So Elusive?"

In this issue of Neuron, Yokoi and Diedrichsen (2019) use a finger keyboard task to show that sequences are widely represented across cortex but that only single elements are represented in primary motor cortex. These results suggest that sequence tasks primarily probe the ability to order discreet actions rather than to execute a skilled continuous sequential action.

Somatosensory cortical excitability changes precede those in motor cortex during human motor learning.

Motor learning is associated with plasticity in both motor and somatosensory cortex. It is known from animal studies that tetanic stimulation to each of these areas individually induces long-term pote...

A systematic review of the proposed mechanisms underpinning pain relief by primary motor cortex stimulation in animals.

Experimental treatments for treating neuropathic pain include transcranial magnetic stimulation (TMS) and invasive electric motor cortex stimulation (iMCS) of the primary motor cortex (M1). Mechanisms...

The effect of coil placement and orientation on the assessment of focal excitability in motor mapping with navigated transcranial magnetic stimulation.

Navigated transcranial magnetic stimulation (nTMS) is used for mapping muscle representations in the primary motor cortex. We used sulcus-aligned mapping and electric field (E-field) modeling to inves...

Dual-hemispheric transcranial direct current stimulation (tDCS) over primary motor cortex does not affect movement selection.

Volition and sense of agency are two primary components of a voluntary or internally generated movement. It has been shown that movement selection cannot be altered without interfering with the sense ...

Somatosensory cortex participates in the consolidation of human motor memory.

Newly learned motor skills are initially labile and then consolidated to permit retention. The circuits that enable the consolidation of motor memories remain uncertain. Most work to date has focused ...

Role of the Posterior Parietal Cortex in the Processing of Sensory Information

Although the primary motor cortex is considered has the common final pathway of motor commands, it is influenced by several structures as, for example, the premotor cortex and the posterio...

Motor Cortex Stimulation for Parkinson's Disease

Deep Brain Stimulation represents the golden standard for surgical treatment of Parkinson disease (PD), but it is not optimally effective for controlling every motor sign and adverse event...

Cortical Contributions to Motor Sequence Learning

The long-term objective initiated with this study is to determine which brain areas functionally contribute to learning a motor skill. The primary hypothesis of this trial is that premotor...

Changes in Motor Cortex Following Exercises for Chronic Low Back Pain

The motor cortex of the brain changes following chronic pain and injury, and this is linked to pain-associated changes in motor behaviour. This study aimed to investigate whether therapeut...

The Efficacy of Motor Cortex Stimulation for Pain Control

The objective is to determine if motor cortex stimulation works for the following conditions: 1. Deafferentation facial pain, 2. Upper extremity complex regional pain syndrome ...

Medical and Biotech [MESH] Definitions

A composite area of the cerebral cortex concerned with motor control and sensory perception comprising the motor cortex areas, the somatosensory areas, the gustatory cortex, the olfactory areas, the auditory cortex, and the visual cortex.

Area of the frontal lobe concerned with primary motor control. It lies anterior to the central sulcus.

Mild or moderate loss of motor function accompanied by spasticity in the lower extremities. This condition is a manifestation of CENTRAL NERVOUS SYSTEM DISEASES that cause injury to the motor cortex or descending motor pathways.

Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation.

Tabular numerical representations of sequence motifs displaying their variability as likelihood values for each possible residue at each position in a sequence. Position-specific scoring matrices (PSSMs) are calculated from position frequency matrices.
