Tesla
The unit of measurement quantifying the strength of a magnetic field. Currently the most common strength used in research and clinical practice (e.g., in using SQUIDs) is 3 Tesla. Prior to the 3-Tesla Machine the most common high-field system was 1.5 Tesla. A 3-Tesla MRI system generates a magnetic field that is twice thestrength of a 1.5 Tesla …

It first appeared in a paper published by Charles Spearman (1863-1945) in 1904. Based on his analysis of the performance of school-aged children on a wide variety of …
α-bungarotoxin (α-BTX)
A 74 amino-acid substance that presynaptically blocks neuromuscular transmission. It is one of the so-called curare mimetic α-neurotoxins, which are among the most lethal constituents of venom in the snake Bungarus multicinctus. These toxins bind with very high affinities and selectivities to the nicotinic acetylcholine receptor (AcChoR), and in doing so block neuromuscular transmission through preventing …
At-risk concept
One implying the probability of an adverse outcome. In developmental research, typically one risk factor (e.g., very preterm birth) is used to predict other risk factors (e.g., cerebral palsy). The term ‘at-risk’ as a medical concept originated in epidemiology, which in turn adopted it from the insurance industry that used it in relation to mathematical …
