Abstract
We use a combination of in vivo quantitative proteomics and analyses of cyclin E knockout mice to demonstrate that in terminally differentiated neurons cyclin E forms complexes with Cdk5 and controls synapse function by restraining Cdk5 activity. Ablation of cyclin E led to a decreased number of s...

Abstract
We show that nest inheritance can explain the presence of unrelated helpers in a classic social insect model, the primitively eusocial wasp Polistes dominulus. We found that subordinate helpers produced more direct offspring than lone breeders, some while still subordinate but most after inheriting...

Abstract
We found that mice carrying nAChR β2-subunit deletions have impaired attention performance. Efficient lentiviral vector-mediated reexpression of functional β2-subunit-containing nAChRs in PFC neurons of the prelimbic area (PrL) completely restored the attentional deficit but did not affect impulsi...

Abstract
We tracked 24 hares and 34 cottontails in a protected area of northwestern Italy. Hares were found in different sites every week, while cottontails used the same site for two weeks, and occasionally for longer. It is supposed that this periodic nest switching reduces the risk of predation and parasi...

Macroscopic renal calculi were seen in 50 of 492 (10.2 per cent) wild Eurasian otters found dead in England from 1988 to 2007. Forty-eight adults and two subadults were affected. Calculi were present in 15.7 per cent (31 of 197) of adult males and 12.7 per cent (17 of 134) of adult females. There was...

We examined the extracellular levels of DA, behavioural deficits and the response to L-DOPA treatment in severely intoxicated mice. The MPTP intoxication produced more than a 90% reduction in tissue DA and a 65% decline in extracellular DA levels. In-vivo binding did not show any increased racloprid...

Abstract
We show here that establishment of select CNS longitudinal tracts and formation of precise mechanosensory afferent innervation to the same CNS region are coordinately regulated by the secreted semaphorins Sema-2a and Sema-2b. Both Sema-2a and Sema-2b utilize the same neuronal receptor, plexin B (Ple...

Whereas the harsh touch response depends solely on cell-autonomous mechanosensory channels, gentle nose touch responses require f...

Abstract
We show that in freely behaving rats after a long period in an awake state, cortical neurons can go briefly 'offline' as in sleep, accompanied by slow waves in the local EEG. Neurons often go offline in one cortical area but not in another, and during these periods of 'local sleep', the incidence of...

Abstract
We compared B. indica under a high-fiber diet and a standard rat diet using video monitoring. Our results show that B. indica are mainly active and feed at night, typical of nocturnal animals. A high-fiber diet resulted in a longer time to feed and become active at night and reduced the time spent f...
