Arc mRNA induction in striatal efferent neurons associated with response learning.

29 Jun 2007 The dorsal striatum is involved in motor-response learning, but the extent to which distinct populations of striatal efferent neurons are differentially involved in such learning is unknown. Activity-regulated, cytoskeleton-associated (Arc) protein ...

Executive function in preschoolers with autism: evidence consistent with a secondary deficit.

29 Jun 2007 Recent research on executive function (EF) deficits in autism has led investigators to conclude that EF deficits are secondary to the disorder. The current study has two major goals: (1) Examine whether specific EF deficits are present in the ...

Improving postswitch performance in the dimensional change card-sorting task: the importance of the switch and of pretraining by redescribing the test cards.

25 Jun 2007 The dimensional change card-sorting task (DCCS) is used to assess the executive abilities of young children. Typically, 3-year-olds have difficulty in performing this task. However, the exact nature of this difficulty is still being debated. In the ...

The impact of stimulus-specific practice and task instructions on response congruency effects between tasks.

31 May 2007 In task switching experiments participants have to respond to the same set of stimuli while task instructions vary (e.g., digit stimuli are assigned to left- or right-sided key presses by means of magnitude vs. parity classification). Response ...

Habit reversal training for the itch-scratch cycle associated with pruritic skin conditions.

30 May 2007 Habit reversal therapy was originally developed by Azrin and Nunn in 1977 as a multicomponent treatment for nervous tics and habits. Their premise for clinical intervention was that an old habit can be broken by replacing it with a new, more ...

Benzodiazepines impair the acquisition and reversal of olfactory go/no-go discriminations in rats.

30 May 2007 The present study assessed whether benzodiazepines impair the acquisition, performance, and reversal of olfactory and auditory go/no-go discriminations in rats. Experiment 1 showed that midazolam (0.5-2 mg/kg sc) did not affect the performance of a ...

Probabilistic reversal learning impairments in schizophrenia: further evidence of orbitofrontal dysfunction.

5 May 2007 Impairments in feedback processing and reinforcement learning appear to be prominent aspects of schizophrenia (SZ), which may relate to symptoms of the disorder. Evidence from cognitive neuroscience investigations indicates that disparate brain ...

Spatial and visual discrimination reversals in adult and geriatric rats exposed during gestation to methylmercury and n-3 polyunsaturated fatty acids.

4 May 2007 Fish contain essential long chain polyunsaturated fatty acids (PUFAs), particularly docosahexaenoic acid (DHA), an omega-3 (or n-3) PUFA, but are also the main source of exposure to methylmercury (MeHg), a potent developmental neurotoxicant. Since ...

Visual discrimination by heifers (Bos taurus) of their own species.

29 Apr 2007 Species discrimination has been described in several taxa but rarely in domestic animals. In contrast to wild species, domestic species present a great phenotypic variety. This study investigated whether 10 Prim'Holstein heifers (Bos taurus) could ...

Separating cue encoding from target processing in the explicit task-cuing procedure: are there "true" task switch effects?

29 Apr 2007 Six experiments were conducted to separate cue encoding from target processing in explicitly cued task switching to determine whether task switch effects could be separated from cue encoding effects and to determine the nature of the representations ...
