To explore that question, Mazmanian and colleagues at Caltech used a mouse model of autism that is thought to approximately recreate three of the disorder's hallmark deficits: lack of social interaction, decreased communication (mice normally emit ultrasonic, birdsonglike chirps), and repetitive behaviors such as compulsive grooming or burying marbles.
Purkinje cells normally emit action potentials at a high rate even in the absence of the synaptic input.
It will produce a pheromone called E-beta-farnesene that is normally emitted by aphids when they are threatened by something.
The sun normally emits bursts of charged particles called coronal mass ejections (lower left of image), but they either never strike the Earth or are too weak to do much damage.
Rothamsted's wheat contains genes that have been synthesised in the laboratory; a gene will produce a pheromone called E-beta-farnesene that is normally emitted by aphids when they are threatened by something.
They not only provide illumination at night but are also instrumental in avoiding the emission of greenhouse gases normally emitted from burning the wick and kerosene in the latter.
Blebs of Brk1 depleted cells were emitted at sites where lamellipodia and membrane ruffles were normally emitted.
The fluorescence protein normally emits green fluorescence in the unactivated state, but can be activated by ultra-violet (UV) light to emit red fluorescence.
In the second experiment (Figure 4B), naive and oviposition-experienced parasitoids were exposed to the volatiles normally emitted at 05:00–08:00 and 14 00 17:00 simultaneously.
When sites were moved posteriorly into the caudal half of shell, muscimol microinjection suppressed or nearly abolished positive-valence hedonic reactions that are normally emitted to sucrose taste (e.g., tongue protrusions and paw licking) at both 15 min and 1 hr after microinjection (15 min: F 1,9) = 10.970, p = .009; 1 hr: F 1,10) = 11.962, p = .006; Fig. 3, 5, Fig S1).
Simultaneously, in caudal shell, muscimol microinjections dramatically increased the number of negative-valence aversive reactions (gapes, headshakes, forelimb flails), which are normally emitted to quinine taste (15 min: F 1,9) = 12.880, p = .006; 1 hr: F 1,10) = 11.165, p = .007, Fig. 3, 5, Fig S1).
