Emphasizes ectodermal-mesodermal interaction but focuses on the genesis of specialized structures like feathers (ectodermal) and muscles, cartilage, and bone. The sum of these interactions and other factors which govern normal development may be important in regulating the regeneration of particular structures in postembryonic individuals.…

Presents a paper that relates human behaviors, such as pleasure, pain, learning, and speech to specific anatomical areas of the brain. (MLH)

Results from the Myers-Briggs Type Indicator (MBTI) for 259 nursing students were compared with achievement on examinations in an anatomy and physiology course. Factor analysis demonstrated no relationship between examination scores and any of the individual personality traits purported to be measured by MBTI. Analysis of variance revealed no…

Presents an activity that helps students visualize the major systems of the human body. Involves students building models of those systems, and gives them an understanding of the relationships between different organs by enabling them to see the organs' positions in the body. (JRH)

This study of eight growth-retarded children with Down's syndrome (aged 1 to 6.5 years) found that administration of growth hormone was more effective than either L-dopa or clonidine. Results suggest that children with Down's syndrome have both anatomical and biochemical hypothalamic derangements resulting in decreased growth hormone secretion and…

Students use a dead bird to learn about bird life, anatomy, and death. Students examine a bird body and discuss what happened to the bird. Uses outdoor education as a resource for learning about animals. (SAH)

Explores and interprets the history of anatomy education, drawing on subjective commentary and objective data from various historical periods. Suggests that although anatomy is in decline from a scientific point of view, dissection is enjoying a revival as a vehicle for teaching humanist values in medicine. (SLD)

Describes a pilot study investigating possible differences between learner retention of anatomical information when presented in digital two-dimensional and digital three-dimensional format. Art students (n=36) were randomly assigned to the two-dimensional and three-dimensional treatments. No significant differences in test scores resulted.…

Research on how the brain implements reading has produced results of remarkable consistency, especially on the functional anatomy of single word reading. We examine the general features of this emerging knowledge and draw attention to the extent to which it converges with results from other methods of reading science in several areas: reading…

Although Homo sapiens emerged in Africa some 170,000 years ago, the origins of "modern" behavior, as expressed in technology and art, are attributed to people who migrated out of Africa around 50,000 years ago, creating what has been called a human revolution in Europe and Asia. There is recent evidence that a mutation of the FOXP2 gene (forkhead…

Background: Are brain volumes of individuals with Pervasive Developmental Disorder (PDD) still enlarged in adolescence and adulthood, and if so, is this enlargement confined to the gray and/or the white matter and is it global or more prominent in specific brain regions. Methods: Brain MRI scans were made of 21 adolescents with PDD and 21 closely…

In the cosmetic tongue split operation, the anterior tongue blade is split along the midline of the tongue. The goal of this case study was to obtain preliminary data on speech and tongue motility in a participant who had performed this operation on himself. The participant underwent an articulation test and a tongue motility assessment, as well…

Through this middle school curriculum, students observe bird feeders outside their classrooms, learn to identify birds that visit, and use a simple protocol for counting the birds and collecting other data before sending it to Cornell scientists via the Internet. The activities within the curriculum are inquiry-based and interdisciplinary. This…

The terrestrial slug "Limax" is able to acquire short-term and long-term memories during aversive odor-taste associative learning. We investigated the effect of the selective serotonergic neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) on memory. Behavioral studies indicated that 5,7-DHT impaired short-term memory but not long-term memory. HPLC…
