“…During an episode of SNA a significant portion of neurons are recruited and experience increases in cytoplasmic calcium, important in several aspects of development (Katz and Shatz, 1996; Zhang and Poo, 2001; Spitzer, 2002). In the developing spinal cord embryonic limb movements are generated by spontaneous network activity (Bekoff et al, 1975; Hamburger, 1977; O’Donovan et al, 1998a), which are known to be important in motoneuron axonal pathfinding (Hanson and Landmesser, 2004) and for proper muscle and joint development (Ruano-Gil et al, 1978; Toutant et al, 1979; Roufa and Martonosi, 1981; Persson, 1983; Hall and Herring, 1990; Jarvis et al, 1996). …”

Homeostatic plasticity refers to mechanisms that the cell or network engage in order to homeostatically maintain a preset level of activity. These mechanisms include compensatory changes in cellular excitability, excitatory and inhibitory synaptic strength and are typically studied at a developmental stage when GABA or glycine are inhibitory. Here we focus on the expression of homeostatic plasticity in the chick embryo spinal cord at a stage when GABA is excitatory. When spinal activity is perturbed in the living embryo there are compensatory changes in postsynaptic AMPA receptors and in the driving force for GABAergic currents. These changes are triggered by reduced GABAA receptor signaling, which appears to be part of the sensing machinery for triggering homeostatic plasticity. We compare and contrast these findings to homeostatic plasticity expressed in spinal systems at different stages of development, and to the developing retina at a stage when GABA is depolarizing.

“…When nicotine is administered, skeletal muscle and some autonomic functions are affected. Such movements are important during embryogenesis for differentiation and maturation of the musculoskeleton (Drachman and Sokoloff, 1966;Hall and Herring, 1990;Hamburger and Oppenheim, 1967;Mclennan, 1983;Oppenheim, 1975Oppenheim, , 1984Oppenheim et al, 1978;Shimazu et al, 1990;Toutant et al, 1979). Hence, it can affect the embryonic movements in two directions, depending on dose.…”

Cigarette smoking is unrivaled among developmental toxicants in terms of total adverse impact on the human population. Maternal tobacco use during pregnancy adversely affects prenatal and postnatal growth and increases the risk of behavioral and developmental defects in children and adolescents. In the current study, the effects of different preparations of nicotine and mainstream whole smoke solutions (MSWSS) on embryonic movements during neonatal development were examined in vivo, using the chicken embryo model, recorded in real-time by a video camera. It was observed that low doses of nicotine induced hyperactivity and higher doses induced hypoactivity. Accordingly, a significant (p < 0.01) decrease in movements was observed by application of 10 microg of nicotine and different preparations of MSWSS. A dose-dependent decrease in embryonic movements was observed, which did not recover by the end of experiment. It was concluded that nicotine could alter embryonic movements, which are important during embryogenesis for differentiation and maturation of the body systems.
