The Impact of Social Comparisons More Related to Ability vs. More Related to Opinion on Well-Being: An Instagram Study.

Social networks are gaining widespread popularity, with Instagram currently being the most intensively used network. On these platforms, users are continuously exposed to self-relevant information that fosters social comparisons. A distinction is made between ability-based and opinion-based comparison dimensions.

Stereotactic surgery in the management of intracranial disorders.

Fifty-six stereotactic procedures (thirty-eight stereotactic biopsies, 13 stereotactic craniotomies, and 5 implantations of intracranial catheters) were performed on 54 patients at the University of Missouri between 1990 and 1994. In 89.5% of cases a definitive diagnosis was made by stereotactic biopsy with a major complication rate of 2.

Sensory nerve crush and regeneration and the receptive fields and response properties of neurons in the primary somatosensory cerebral cortex of cats.

Extracellular recordings were made of activity evoked in neurons of the forepaw focus of somatosensory cerebral cortex by electrical stimulation of each paw in control cats and cats that had undergone crush injury of all cutaneous sensory nerves to the contralateral forepaw 31 to 63 days previously. Neurons responding only to stimulation of the contralateral forepaw were classified as sa; neurons responding to stimulation of both forepaws were classified as sb; neurons responding to stimulation of both contralateral paws were classified as sc; and neurons responding to stimulation of at least three paws were classified as m. The ratio sa:sb:sc:m neurons was 46:3:0:0 in control cats and 104:15:3:26 in cats that had undergone nerve crush 1-2 months prior to study.

Dysphagia and dysphonia secondary to anterior cervical osteophytes.

A 77-year-old man presented with a 4-year history of progressive dysphagia to the point that he could no longer swallow solid foods. During the past several months, he had developed dysphonia. Cervical spine x-ray films demonstrated massive anterior degenerative osteophytic spurs between C-3 and C-7.
