The paper shows how the verbal lexicon can be formalised in a way that captures and exploits generalisations about the alternation behaviour of verb classes. An alternation is a pattern in which a number of words share the same relationship between • a pair of senses. The alternations captured are ones where the different senses specify different relationships between syntactic complements and ...

Performance on various spatial tasks is superior in the presence of extramaze cues that provide guidance in locating the goal. This study was an investigation of the effect of such cues on nonrewarded, continuous spontaneous alternation in a plus-maze, a spatial task with no explicit reinforcement. Rats were tested in five daily sessions. Alternation scores, which reflect how frequently the lea...

We propose a technique to make a robot execute free and solitary dance movements on music, in a manner which simulates the dynamic alternations between synchronisation and autonomy typically observed in human behaviour. In contrast with previous approaches, we preprogram neither the dance patterns nor their alternation, but rather build in basic dynamics in the robot, and let the behaviour emer...

Crystals with full tetrahedral symmetry may exhibit antichiral ferromagnetic ordering. This spontaneous modulation of the magnetization direction is characterized by a spatial alternation between right and left handedness. In addition to unconventional ground state, revealed ordering gives rise rich phenomena, such as unique magnetic domains skyrmions.

Abstract Chronic exposure to methamphetamine (METH) causes severe and persistent cognitive impairment. The present study aimed investigate the role of dynorphin/κ opioid receptor (KOR) system in development METH‐induced We found that mice showed significant impairment novel object recognition test (NOR) following daily injections METH (10 mg/kg) for seven consecutive days. Systemic blockade KOR...

We previously showed that inhibition of repeated electroconvulsive shock (ECS)-induced seizures through 7-day administration of anti-epileptic drugs suppressed the impairment of spontaneous alternation behavior in the Y-maze test in rats. To clarify the precise mechanism(s), we investigated the effect of valproate on such impairment and examined the levels of brain-derived neurotrophic factor (...

Although diathesis alternations have been used as features for manual verb classification, and there is recent work on incorporating such features in computational models of human language acquisition, work on large scale verb classification has yet to examine the potential for using diathesis alternations as input features to the clustering process. This paper proposes a method for approximati...

Glucose injections attenuate deficits in memory under several conditions in both rodents and humans. The present study examined effects of glucose on memory in two such amnesic populations, scopolamine-treated and old mice, and then assessed effects of glucose on brain (lHJ2deoxyglucose (2DG) uptake. In Experiment lA, scopolamine (3 mg/kg, i.p.) significantly impaired performance of mice tested...

Fibrinogen is a secreted glycoprotein that is synthesized in the liver, although recent in situ hybridization data support its expression in the brain. It is involved in blood clotting and is released in the brain upon injury. Here, we report changes in the extracellular levels of fibrinogen α-chain-derived peptides in the brain after injections of saline and morphine. More specifically, in ord...
