Firing Hot, Firing Cold: How Poikilotherms Compensate for Temperature Swings
If you are reading this, you have one less problem than the crabs that are the subject of a new study in this issue of PLoS Biology. Humans, like all mammals (as well as birds), are ‘‘warm-blooded,’’ or more correctly ‘‘homeothermic,’’ meaning we maintain our core body organs at a constant temperature. We expend considerable energy to do so, and may die when we cannot. In contrast, crabs, cod, ...
متن کاملEffect of firing temperature on the properties of inorganic high temperature phosphate adhesive
High-temperature adhesives are considered for high-temperature applications such as the refractory industry. In this research, inorganic high-temperature phosphate-based adhesive was prepared using alumina and micro silica as the main raw materials and monoaluminum phosphate as a binder. The effect of firing temperature on the properties of the adhesive including phases, microstructure, compres...
متن کاملHow Early Is Firing Required for Wiring?
Activity is known to be important for the refinement of neural connections in the developing brain. In this issue of Neuron, Hanson and Landmesser provide evidence that GABA-dependent spontaneous bursting of motor neurons in the embryonic spinal cord is required for the correct execution of an early axon pathfinding decision.
متن کاملHow Adaptation Makes Low Firing Rates Robust
Low frequency firing is modeled by Type 1 neurons with a SNIC, but, because of the vertical slope of the square-root-like f-I curve, low f only occurs over a narrow range of I. When an adaptive current is added, however, the f-I curve is linearized, and low f occurs robustly over a large I range. Ermentrout (Neural Comput. 10(7):1721-1729, 1998) showed that this feature of adaptation paradoxica...
متن کاملFiring back
voluntarily herd shoals of fish towards fishing boats. The fishermen benefit from enhanced catches and the dolphins feed on the entrapped fish, as well as getting some rewards from the fishermen. Nonetheless, numbers of dolphins have declined in Myanmar as a result of electrocution through illegal electric fishing, entanglement in nets, mercury poisoning and habitat loss from gold mining. Myanm...
