“…3, Areas II and III are bilaterally located at the level of the rostral medulla and pons, respectively. From a comparison with anatomical information [11,20], we believe that Area III corresponds to the PBN. Although the structural basis of Area II has not yet been clarified, possible candidates include the A5 noradrenergic group, which lies ventrally between the NTS and the PBN.…”

“…The methods used for multiple-site optical recording of electrical activity in embryonic nervous systems are described in detail elsewhere [for reviews, see 7,19,20]. In brief, bright-field illumination was provided by a 300 W tungsten-halogen lamp (Type JC-24 V/300 W, Kondo Philips Ltd., Tokyo, Japan) driven by a stable dc-power supply.…”

“…Using the optical technique, we have analyzed electrical activity in embryonic nervous systems [for reviews, see 4, [17][18][19][20], especially that in the brainstem related to autonomic function. In embryonic chick [8,9,14,15,28] and rat [13,27] brainstems, we examined spatiotemporal patterns of neural activity evoked by N.X stimulation and demonstrated three-dimensional profiles of the vagal sensory nucleus (nucleus of the tractus solitarius (NTS)) and motor nucleus (dorsal motor nucleus of the vagus nerve (DMNV)).…”

Spontaneous embryonic movements, called embryonic motility, are produced by correlated spontaneous activity in the cranial and spinal nerves, which is driven by brainstem and spinal networks. Using optical imaging with a voltage-sensitive dye, we have revealed previously that this correlated activity is a widely propagating wave of neural depolarization, which we termed the depolarization wave. We have observed in the chick and rat embryos that the activity spread over an extensive region of the CNS, including the spinal cord, hindbrain, cerebellum, midbrain and forebrain. One important consideration is whether a depolarization wave with similar characteristics occurs in other species, especially in different mammals. Here, we provide evidence for the existence of the depolarization wave in the mouse embryo by showing that the widely propagating wave appeared independently of the localized spontaneous activity detected previously with Ca(2+) imaging. Furthermore, we mapped the origin of the depolarization wave and revealed that the wave generator moved from the rostral spinal cord to the caudal cord as development proceeded, and was later replaced with mature rhythmogenerators. The present study, together with an accompanying paper that describes pharmacological properties of the mouse depolarization wave, shows that a synchronized wave with common characteristics is expressed in different species, suggesting fundamental roles in neural development.

“…Results described here have been published recently in our research papers. 28,29 Details of the optical recording with voltagesensitive dyes have been described in several reviews [30][31][32][33][34][35][36][37][38] and will not be discussed in this review. Figure 1 shows examples of multiple-site optical recordings of spontaneous activity obtained from the brainstem-whole spinal cord ( Fig.…”
