The development of the central nervous system is dependent on spontaneous action potentials and changes in [Ca2+]i occurring in neurons [1–4]. In the mammalian retina, waves of spontaneous electrical activity spread between retinal neurons, raising

Excessive activation of glutamate receptors in the late embryonic and adult retina leads to excitotoxic cell death through an increase in intracellular calcium concentration. Here we use the cobalt-staining technique of Pruss et al. to investigate th

Axonal elongation and the transformation of growth cones to synaptic terminals are major steps of brain development and the molecular mechanisms involved form the basis of the correct wiring of the nervous system. The same mechanisms may also contrib

We have used dye injection and immunolabeling to investigate the relationship between connexin (Cx) expression and dye coupling between ganglion cells (GCs) and other cells of the embryonic chick retina between embryonic days 5 and 14 (E5-14). At E5,

Correlated spiking activity and associated Ca(2+) waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA(B) receptors, regulates the temporal characteristics of Ca(2+) wave

Waves of spontaneous electrical activity and calcium transients occur in the retina during its development. Recent work raises the question of how these waves are produced and propagated.

Spontaneous calcium transients occur in the ventricular zone of the chick retina and result from the endogenous release of neurotransmitters in the absence of action potentials. Calcium transients resulting from the activation of purinergic and musca

Electrophysiological experiments have shown in both birds and mammals that remote parts of the retina, several millimetres apart, interact at the retinal level1,2. The anatomical basis of this is poorly understood, although in mammals some cells in t
