Olfaction.
The main and accessory olfactory systems have received considerable attention on the part of scientists and clinicians during the last decade, largely because of (a) quantum advances in understanding their genetically expressed receptor mechanisms, (b) evidence that their receptor cells undergo neurogenesis and both programmed and induced cell death, and (c) important technical and practical de...
متن کاملElectric Times in Olfaction
Recent work established the spread of interglomerular excitation in the Drosophila antennal lobe. Two papers in this issue of Neuron, by Huang et al. and Yaksi and Wilson, show that cholinergic krasavietz local interneurons are a major substrate for this spread of excitation, predominantly via electrical coupling.
متن کاملDeterminants of eggshell strength in endangered raptors.
We compared eggshell strength in a group of falcon taxa including the peregrine falcon (Falco peregrinus peregrinus), the red shaheen falcon (F. peregrinus babylonicus), the saker falcon (F. cherrug), the gyr falcon (F. rusticolus) and some interspecific and intraspecific hybrids. Our results showed that smaller falcons (<1,000 g) of the peregrine group have eggshells that are significantly sof...
متن کاملRaptors lack lower-field myopia
The presence of lower-field myopia (described in chickens, pigeons, quail and amphibians) allows these animals to keep the ground in focus while performing other visual tasks. A relationship has also been reported between the eye height and the degree of myopia observed. All of the animals reported in the literature to date are ground-foraging species. Using infrared neutralizing video retinosc...
متن کاملRaptors-inroads to multifingered grasping
In this work, we consider the grasping and manipulation strategies of raptors, focusing on the particularly successful case of the osprey. The osprey makes superb use of its two four-digit feet, each of which has ve degrees of freedom. Its manipulation strategies exploit not only quasistatic but also dynamic grasping, particularly in shing, for which the bird is highly renowned. In this paper, ...
