Motor Development: Activity Matters After All
Developing spinal networks are constructed through the integration of local microcircuits and the ongoing incorporation of later-developing neurons. This process is dependent on neuronal activity prior to synaptogenesis.
متن کاملPlant Development: Size Matters, and It's All Down to Hormones
How do plants determine the number of dividing cells required to optimise root growth and ensure seedling establishment? The signals auxin, cytokinin and gibberellin control the balance between cell division and differentiation by regulating SHY2.
متن کاملSystolic pressure is all that matters.
Blood pressure is usually expressed as two com ponents—diastolic and systolic pressures. Systolic hypertension is much more common than diastolic hypertension, and systolic blood pressure contributes more of the huge global disease burden attributable to hypertension than does diastolic pressure. However, there has undoubtedly been confusion about the relative merits of targeting systolic versu...
متن کاملMotor neuronal activity varies least among individuals when it matters most for behavior.
How does motor neuronal variability affect behavior? To explore this question, we quantified activity of multiple individual identified motor neurons mediating biting and swallowing in intact, behaving Aplysia californica by recording from the protractor muscle and the three nerves containing the majority of motor neurons controlling the feeding musculature. We measured multiple motor component...
متن کاملRoot development: Quiescent center not so mute after all
Many functions have been attributed to the quiescent center of a root apical meristem, from stem cell reservoir to pattern-generating center. Limited laser ablation of the quiescent center in Arabidopsis has now revealed that it acts to suppress differentiation and to maintain the surrounding initial cells as stem cells.
