The earliest research into thinking machines was inspired by a confluence of ideas that became prevalent in the late 1930s, 1940s, and early 1950s. Recent research in neurology had shown that the brain was an electrical network of neurons that fired in all-or-nothing pulses. Norbert Wiener's cybernetics described control and stability in electrical networks. Claude Shannon's information theory described .

The yolk syncytial layer (YSL) plays crucial roles in early zebrafish development. The YSL is a transient extra-embryonic syncytial tissue that forms during early cleavage stages and persists until larval stages.
The yolk syncytial layer (YSL) forms at the mid-blastula (512-1k cell stage), when some of the marginal blastomeres divide and release their nuclei into the yolk cell (Kimmel and Law, 1985b).At this time, three distinct cell populations can be distinguished. The first of these is the yolk syncytial layer (YSL). The YSL is formed at the ninth or tenth cell cycle, when the cells at the vegetal edge of the blastoderm fuse with the underlying yolk cell. In the YSL precursor, Nanog-like directly activates Mxtx2, which, in turn, specifies the YSL lineage by directly activating the expression of YSL genes. During the late blastula stage, the YSL functions as a signaling center producing Nodal molecules for . Distribution of FITC-aequorin following injection at the 1-cell or 128-cell stages. A microinjection protocol was designed to load aequorin preferentially into the yolk syncytial layer (YSL) rather than into the blastoderm.
To investigate a possible role of the yolk syncytial layer (YSL) in the development of the medaka embryo, blastoderms were isolated at different stages of embryogenesis either with or without the layer and were incubated in a culture medium.
This gradual cessation of YSL nuclear divisions clearly sets the stage for the contraction of YSL cytoplasm and thus the beginning of gastrulation. We call this the YSL transition. It is not to be confused with the midblastula transition, which occurs 3-4 hours earlier.When YSL formation completes at mid-blastula stage, three compartments of continuous cortical cytoplasm can be distinguished in the yolk cell (Fig. lC,D). A thin, anuclear yolk cytoplasmic layer (YCL) surrounds the bulk of the yolk mass with the vegetal pole. . The YSL forms between the yolk and overlying embryonic cells at around 2.5 hpf, during the mid-blastula transition, when activation of the zygotic genome occurs . The YSL forms via the collapse of a subset of embryonic margin cells, which are the outermost embryonic cells adjacent to the yolk.

Why the YSL appears to be resistant to a broad range of apoptotic stimuli remains an open question. Indeed, in zebrafish, the YSL is crucial for early embryonic development, uncontrolled activation of the cell death program during gastrulation being embryonic lethal.
