Neuronal Development: Specifying a Hard-Wired Circuit
The formation of neuronal circuits that relay distinct olfactory information is thought to depend on cues provided by pre-synaptic receptor neurons. But direct visualization of second order neurons in Drosophila now suggests that dendritic targeting occurs independently of interactions with incoming sensory neurons.
متن کاملIs homosexual behaviour hard-wired? Sexual orientation and brain structure.
The search for neurobiological explanations for human behaviours is in full flow, spurred on by the same reductionist philosophy and technological advances that are proving so dominant in the investigation of psychiatric diseases. Homosexuality is no exception, with recent studies reporting on its possible genetic basis (Hamer et al. 1993) and biological correlates (Byne & Parsons, 1993). One a...
متن کاملOnline Packet Scheduling with Hard Deadlines in Wired Networks
The problem of online job or packet scheduling with hard deadlines has been studied extensively in the single hop setting, whereas it is notoriously difficult in the multihop setting. This difficulty stems from the fact that packet scheduling decisions at each hop influences and are influenced by decisions on other hops and only a few provably efficient online scheduling algorithms exist in the...
متن کاملNeuronal Development: Specifying a Hard-Wired Circuit Dispatch
During sensory development, abundant neurons are created in the brain that become functional by precisely extending processes to synapse with determined targets. In contrast to the visual or somatosensory system, olfactory information is mediated by a large number of distinct receptor neurons, randomly intermingled in the olfactory epithelium, and the axons from cells expressing identical ligan...
متن کاملMicrofluidic traps for hard-wired operations on droplets.
We present microfluidic modules (traps) that allow us to lock, shift, dose and merge micro-aliquots of liquid precisely. The precision is hard-wired into the geometry of the device: small values of the capillary number guarantee reproducibility of operation over a range of rates of flow that need not be controlled precisely. The modules can be integrated into systems that perform complicated pr...
