Do observers search for camouflaged targets by looking through the distractors or by scrutinizing the target-similar background? In four experiments observers searched for toy targets among distractors under varying set size and target-background similarity (TBS) conditions. Manual errors and RTs increased with TBS, although search slopes did not significantly differ. Eye movement analyses reve...

The equilibrium potential for GABA-A receptor mediated currents (EGABA) in neonatal central neurons is set at a relatively depolarized level, which is suggested to be caused by a low expression of K+/Cl- co-transporter (KCC2) but a relatively high expression of Na+-K+-Cl- cotransporter (NKCC1). Theta-burst stimulation (TBS) in stratum radiatum induces a negative shift in EGABA in juvenile hippo...

OBJECTIVE To determine whether the marks in the third year Objective Structured Clinical Examination (OSCE) were affected by the collusion reported by the students themselves on an electronic discussion board. DESIGN A review of the student discussion, examiners' feedback and a comparison of the marks obtained on the 2 days of the OSCE. PARTICIPANTS 255 third year medical students. SETTIN...

Towards the middle of .the fourteenth century some Italian merchants who were occupied in trading with China by the overland route were besieged by the Tartars in a small town on the river Don. They were, however, driven out of this town, and many of them, together with their merchandise from China, found refuge in the fortified post of Caff a, in the Crimea. Later they were again besieged in t...

Deciphering and storing information coded in different firing patterns are important properties of neuronal networks, as they allow organisms to respond and adapt to external and internal events. Here we report that hippocampal CA1 pyramidal neurons respond to brief bursts of high-frequency stimulation (HFS) and θ burst stimulation (TBS) with long-lasting enhanced responses (long-term potentiat...

This study investigated body surface temperature (Tbs) in 22 lizards of 18 species. The difference between Tbs and ambient temperature (Ta) was correlated with size. The greater Tbs 2 Ta differentials, which were recorded in larger lizards, may occur as a result of heat transfer from the core to surface in prevention of overheating. The structure of the integument may contribute to heat dissipa...

The amplitude of backpropagating action potentials (BAPs) is attenuated, either activity- or neurotransmitter-dependently in the apical dendrite of hippocampal pyramidal neurons. To test the possibility that this BAP attenuation may contribute to regulating the inducibility of long-term potentiation (LTP), BAPs evoked by theta-burst stimulation (TBS), a standard protocol for LTP induction, to a...

A recently developed diagnostic tool, trabecular bone score (TBS), can provide quality of trabecular microarchitecture based on images obtained from dual-energy X-ray absorptiometry (DXA). Since patients receiving glucocorticoid are at a higher risk of developing secondary osteoporosis, assessment of bone microarchitecture may be used to evaluate risk of fragility fractures of osteoporosis. In ...
