Electroencephalographic power ratio and peak frequency difference associate with central sensitization in chronic pain.

Central sensitization, or increased responsiveness of the central nervous system to sensory input, is present in many chronic pain patients. Clinically, it is detected through subjective, patient-reported measures. There is a need for reliable, direct measurements of neural response to controlled stimuli to quantify neuronal dysfunction in pain.

Selective ion transport through hydrated micropores in polymer membranes.

Ion-conducting polymer membranes are essential in many separation processes and electrochemical devices, including electrodialysis, redox flow batteries, fuel cells and electrolysers. Controlling ion transport and selectivity in these membranes largely hinges on the manipulation of pore size. Although membrane pore structures can be designed in the dry state, they are redefined upon hydration owing to swelling in electrolyte solutions.

An Unusual Case of Contralateral Hypoglossal and Recurrent Laryngeal Nerve Palsies Following Endotracheal Intubation.

We present an unusual case of a 62-year-old male presenting with contralateral hypoglossal and recurrent laryngeal nerve palsies following endotracheal intubation for emergency cardiac surgery. Postoperative, the patient was referred to Speech and Language Therapy due to concerns regarding the safety of his swallow. Oromotor assessment revealed left-sided tongue weakness and aphonia.

Perspectives on factors influencing quality of life in persons with long-term spinal cord injury: a qualitative study.

Study Design: Qualitative Cohort Study.

Objectives: Many people with long-term spinal cord injury (SCI) develop adaptation strategies to succeed. Understanding the factors that support their capacity to adapt and develop is important to enhance quality of life of others with SCI.

Lateral inhibition in V1 controls neural & perceptual contrast sensitivity.

Lateral inhibition is a central principle for sensory system function. It is thought to operate by the activation of inhibitory neurons that restrict the spatial spread of sensory excitation. Much work on the role of inhibition in sensory systems has focused on visual cortex; however, the neurons, computations, and mechanisms underlying cortical lateral inhibition remain debated, and its importance for visual perception remains unknown.
