This chapter considers why studies of infant looking and reaching often suggest different patterns of cognitive and perceptual development. In some cases, convergent results have emerged from studies of infant looking and reaching, but differences are common. The most typical results suggest less adult-like perception and cognition in studies of reaching than in studies of looking. Several reaching studies, however, do not fit this pattern, suggesting that reaching actions may be mediated by distinct systems of knowledge and information processing. Comparisons of research on other behaviors, such as crawling and walking, also suggest that infant knowledge systems vary across actions. …

This article, which includes novel unpublished data along with commentary and analysis,

focuses on approaches to link transcriptomic, proteomic, and peptidomic datasets mined from

brain tissue to the original locations within the brain that they are derived from using digital atlas

mapping techniques. We use, as an example, the transcriptomic, proteomic and peptidomic

analyses conducted in the mammalian hypothalamus. Following a brief historical overview, we

highlight studies that have mined biochemical and molecular information from the hypothalamus

and then lay out a strategy for how these data can be linked spatially to the mapped locations in a

canonical brain atlas …
