The laminar structure and conserved cellular organization of mouse visual cortex provide a useful model to determine the mechanisms underlying the development of visual system function. However, the normal development of many receptive field properties has not yet been thoroughly quantified, particularly with respect to layer identity and in the absence of anesthesia. Here, we use multisite ele...

The paper proposes a framework for the integration of leadership and followership. An integral orientation considers that leadership is constitutively linked with followership and vice versa. Facing the diversity of approaches and theories in both fields, a comprehensive conceptualization is presented that is suited to investigating complex, interrelated processes of leading and following. Base...

It is known that the wing scales of the emerald-patched cattleheart butterfly, Parides sesostris, contain gyroid-type photonic crystals, which produce a green structural colour. However, the photonic crystal is not a single crystal that spreads over the entire scale, but it is separated into many small domains with different crystal orientations. As a photonic crystal generally has band gaps at...

BACKGROUND Human sexual orientation is influenced by genetic and non-shared environmental factors as are two important psychological correlates--childhood gender typicality (CGT) and adult gender identity (AGI). However, researchers have been unable to resolve the genetic and non-genetic components that contribute to the covariation between these traits, particularly in women. METHODOLOGY/PRI...

During animal development cellular differentiation is often preceded by an asymmetric cell division whose polarity is determined by the orientation of the mitotic spindle. In the fruit fly, Drosophila melanogaster, the oocyte differentiates in a 16-cell syncytium that arises from a cystoblast which undergoes 4 synchronous divisions with incomplete cytokinesis. During these divisions, spindle or...

BACKGROUND Orientation and positioning of the cell division plane are essential for generation of invariant cleavage patterns and for unequal cell divisions during development. Precise control of the division plane is important for appropriate partitioning of localized factors, spatial arrangement of cells for proper intercellular interactions, and size control of daughter cells. Ascidian embry...

Sexual differentiation leads to the development of distinctive anatomical structures (e.g., gonads and genitalia); it also produces less obvious anatomical shifts in brain, bones, muscles, etc. This study is a retrospective analysis of growth patterns in the hands in relation to sex and sexual orientation. Using data from three published studies, we analyzed four hand traits in adults: hand wid...

Although especially relevant to the adolescent period, the capacity for orienting to the future is innate, identified in early infancy, and – as already noted in Chap. 1 – underlying it are neurophysiological processes generated in the cerebral cortex (Brunia & Boxtel, 2001; Wentworth, Haith, & Karrer, 2001). However, interacting with other innate abilities (such as memory and language), interp...

We examined the relationship between theory of mind (ToM) and engaging in fantasy worlds in a short-term longitudinal study. Engagement in fantasy worlds might advance ToM because engaging in alternative worlds is similar to imagining the world from others’ viewpoints. Fantasy might also be related to preference for describing others’ mental states. To test these theories, we examined relations...

Research on sexual orientation and substance use has established that lesbian, gay, and bisexual (LGB) individuals are more likely to smoke than heterosexuals. This analysis furthers the examination of smoking behaviors across sexual orientation groups by describing how same- and opposite-sex romantic attraction, and changes in romantic attraction, are associated with distinct six-year developm...
