Suggested caption: "From a new brain imaging study at the University of Pennsylvania School of Medicine, SPECT scans were taken of subjects while worshiping versus speaking in tongues. The speaking in tongue images primarily show a decrease of brain activity in the frontal lobes, which is what normally makes us feel as if we're in control. There was also a decrease in activity in the left basal ganglia, which is involved with focusing attention and emotional responses. Finally, the thalamus... (EurekAlert!)

Sleepy fruit flies provide clues to learning and memory Jun 16, 2006
"Although people typically think of mushroom bodies as possessing similar functions to the human hippocampus, the site where long-term memories are made, our lab tends to think of the mushroom bodies functioning more like the thalamus, the relay station through which most sensory input to the brain is targeted," explains Sehgal. "Previous research links the thalamus to a role in human sleep." (There is no human structure that is anatomically similar to the adult mushroom bodies of fruit flies. (EurekAlert!)

Dr. Derbyshire likened the pain perception system in the developing fetus to an alarm system in which the wiring is gradually laid down, but the final connections are not made until 26 weeks gestation, when neuronal projections from the thalamus to the cortex have been completed. The minimum gestational age at which a pain signal may be transmitted from the periphery is seven weeks, the point at which neural projections from the spinal cord can reach the thalamus, he said ... Yet the wiring from... (MedPage Today)
It has been suggested that the minimum level of anatomical development for pain is the completion of the "spinothalamic" muscular link from the spine to the thalamus, the part of the brain that processes information from the senses, at 23-25 weeks. A study published last week from University College London revealed that scans on premature babies from 24 weeks having blood tests showed surges of blood and oxygen in sensory areas of their brains - suggesting pain was being processed.

Leptin is secreted by fat -- the more fat, the more leptin -- yet it is named for the Greek word leptos, which means "thin."
