eye field cell fate commitment involved in camera-type eye formation

The commitment of neurectodermal cells to cells of the eye field and their capacity to differentiate into eye field cells. Eye field cells are neurectodermal cells that will form the optic placode.

magnetoreception by sensory perception of electrical stimulus

The series of events required for an organism to receive an electrical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. Movement in a magnetic field results in an induced electric field, which can be perceived by organisms such as elasmobranch fish.

detection of electrical stimulus involved in magnetoreception

The series of events that contribute to magnetoception in which an electrical stimulus is received and converted into a molecular signal. The stimulus is in the form of an induced electric field resulting from movement in a magnetic field.

magnetoreception by sensory perception of mechanical stimulus

The series of events required for an organism to receive a mechanical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. A magnetic field exerts a torque on a ferromagnetic material (e.g. magnetite) or on a material with diamagnetic anisotropy; organisms that can detect this torque can use it to determine the orientation of the magnetic field.

embryonic heart tube formation via epithelial folding

The process that gives rise to the embryonic heart tube by the cells of the heart field along a linear axis.

optokinetic behavior

The behavior of an organism pertaining to movement of the eyes and of objects in the visual field, as in nystagmus.

obsolete positive regulation of regulation of secondary heart field cardioblast proliferation

OBSOLETE. Any process that activates or increases the frequency, rate or extent of regulation of secondary heart field cardioblast proliferation.

regulation of primary heart field cardioblast proliferation

Any process that modulates the frequency, rate or extent of cardioblast proliferation in the primary heart field. A cardioblast is a cardiac precursor cell. It is a cell that has been committed to a cardiac fate, but will undergo more cell division rather than terminally differentiating. In mammals the primary heart field gives rise to the left ventricle.

cardiogenic plate morphogenesis

The process in which the anatomical structures of the cardiogenic plate are generated and organized. The cardiogenic plate is the first recognizable structure derived from the heart field.

nerve growth factor production

The appearance of nerve growth factor (NGF) due to biosynthesis or secretion by cells in a neuron's target field, resulting in an increase in its intracellular or extracellular levels.
