Multidimensional versus unidimensional pain scales for the assessment of analgesic requirement in the emergency department: a systematic review.

Pain is a multidimensional experience, potentially rendering unidimensional pain scales inappropriate for assessment. Prior research highlighted their inadequacy as reliable indicators of analgesic requirement. This systematic review aimed to compare multidimensional with unidimensional pain scales in assessing analgesic requirements in the emergency department (ED).

Thalamus and Language: What do we know from vascular and degenerative pathologies.

Language is a complex cognitive task that is essential in our daily life. For decades, researchers have tried to understand the different role of cortical and subcortical areas in cerebral language representations and language processing. Language-related cortical zones are richly interconnected with other cortical regions (particularly via myelinated fibre tracts), but they also participate in subcortical feedback loops within the basal ganglia (caudate nucleus and putamen) and thalamus.

Basal ganglia: Their role in complex cognitive procedures in experimental models and in clinical practice.

Apart from the well known role of the basal ganglia (BG) in motor control, their important role in regulating the cognitive functions is emerging. This article traces the scientific work that explores this role of BG in reinforcement learning, perceptual decision making, and other nonmotor pathways (speech fluency, cognition, attention and behaviour). It also highlights the important role played by the BG networks in determining the development of a child's brain.
