Dissociable effects of dopaminergic therapy on spatial versus non-spatial working memory in Parkinsons disease.

There is now evidence for definite and early cognitive deficits in Parkinsons disease (PD), involving, in particular, executive functions and working memory. However, the distinction between visuo-spatial and non-spatial working memory deficits and the ...

Non-identical neural mechanisms for two types of mental transformation: event-related potentials during mental rotation and mental paper folding.

Reaction times, accuracy and 128-channel event-related potentials (ERPs) were measured from 14 normal, right-handed subjects while they performed two different parity-judgment tasks that require transformations of mental images: a relatively simple task ...

Use of orthoses and early intervention physical therapy to minimize hyperpronation and promote functional skills in a child with gross motor delays: a case report.

BACKGROUND AND PURPOSE: This case report describes a physical therapy program that included foot orthoses for a child with excessive pronation and gross motor delay. CASE DESCRIPTION: A 25-month-old girl with a 6-month gross motor delay had excessive ...

From acting on to acting with: the functional anatomy of object-oriented action schemata.

In this chapter it is proposed that object-based actions can be broadly classified into types. In the first, objects are acted on without a specific purpose. In the second, objects are acted with. In the latter case the grasp reflects the subsequent goal ...

A comparison of performance outcomes between the Minnesota Rate of Manipulation Test and the Minnesota Manual Dexterity Test.

This study examined the performance outcomes between two tests of manual dexterity, the Minnesota Rate of Manipulation Test [1] and the Minnesota Manual Dexterity Test (1981). Even though the tests are constructed differently and are different versions ...

Distinct contribution of the cortico-striatal and cortico-cerebellar systems to motor skill learning.

This review paper focuses on studies in healthy human subjects that examined the functional neuroanatomy and cerebral plasticity associated with the learning, consolidation and retention phases of motor skilled behaviors using modern brain imaging ...

Possible role of intramembrane receptor-receptor interactions in memory and learning via formation of long-lived heteromeric complexes: focus on motor learning in the basal ganglia.

Learning in neuronal networks occurs by instructions to the neurons to change their synaptic weights (i.e., efficacies). According to the present model a molecular mechanism that can contribute to change synaptic weights may be represented by multiple ...

The effects of work pace on within-participant and between-participant keying force, electromyography, and fatigue.

A laboratory study was conducted to determine the effects of work pace on typing force, electromyographic (EMG) activity, and subjective discomfort. We found that as participants typed faster, their typing force and finger flexor and extensor EMG ...

Control performance with three translational degrees of freedom.

For multiple degree-of-freedom (DOF) systems, it is important to determine how accurately operators can control each DOF and what influence perceptual, information processing, and psychomotor components have on performance. Sixteen right-handed male ...

A study of manual toothbrushing skills in children aged 3 to 11 years.

The aim of the study was to evaluate toothbrushing management and ability of children in relation to age and gender. The study population consisted of 75 children and were divided into three equal groups as 3-5, 6-8 and 9-11 years of age. The grip type ...
