    Reports an error in "The impact of motivation on cognitive performance in an animal model of the negative and cognitive symptoms of schizophrenia" by Ryan D. Ward, Vanessa Winiger, Kerin K. Higa, Julia B. Kahn, Eric R. Kandel, Peter D. Balsam and Eleanor H. Simpson (Behavioral Neuroscience, 2015[Jun], Vol 129[3], 292-299). There is a text error in the 4th paragraph of the Discussion section. The explanation for the abbreviation OFC was incorrectly listed as occipitofrontal circumference. It should have been orbitofrontal cortex. (The following abstract of the original article appeared in record 2015-18639-001.) Interactions between motivation and cognition are implicated in producing functional impairments and poor quality of life in psychiatric patients. This interaction, however, is not well understood at either the behavioral or neural level. We developed a procedure for mice in which a cognitive measure, sustained attention, is modulated by a motivationally relevant signal that predicts reward probability on a trial-by-trial basis. Using this paradigm, we tested the interaction between motivation and cognition in mice that model the increased striatal D2 receptor activity observed in schizophrenia patients (D2R-OE mice). In control mice, attention was modulated by signaled-reward probability. In D2R-OE mice, however, attention was not modulated by reward-related cues. This impairment was not due to any global deficits in attention or maintenance of the trial-specific information in working memory. Turning off the transgene in D2R-OE mice rescued the motivational modulation of attention. These results indicate that deficits in motivation impair the ability to use reward-related cues to recruit attention and that improving motivation improves functional cognitive performance. These results further suggest that addressing motivational impairments in patients is critical to achieving substantive cognitive and functional gains.

  3. [해외논문]   Greater avoidance of a heroin-paired taste cue is associated with greater escalation of heroin self-administration in rats.  

    Imperio, Caesar G ; Grigson, Patricia S
    Behavioral neuroscience v.129 no.4 ,pp. 380 - 388 , 2015 , 0735-7044 ,

    초록

    Heroin addiction is a disease of chronic relapse affecting over half of its users. Therefore, modeling individual differences in addiction-like behavior is needed to better reflect the human condition. In a rodent model, avoidance of a cocaine-paired saccharin cue is associated with greater cocaine seeking and taking. Here, we tested whether rats would avoid a saccharin cue when paired with the opportunity to self-administer heroin and whether the rats that most greatly avoid the heroin-paired taste cue would exhibit the greatest drug escalation over time, the greatest willingness to work for drug, and the greatest heroin-induced relapse. Adult male Sprague-Dawley rats received 5 min access to a 0.15% saccharin solution followed by the opportunity to self-administer either saline or heroin for 3 hr (short access) or 6 hr (extended access). Following 16 to 18 pairings, terminal saccharin intake was used to categorize the rats into small (>200 licks/5min) or large (

  5. [해외논문]   Attenuation of MK-801-induced behavioral perseveration by typical and atypical antipsychotic pretreatment in rats.   SCI SCIE

    Tuplin, Erin W ; Stocco, Marlaina R ; Holahan, Matthew R
    Behavioral neuroscience v.129 no.4 ,pp. 399 - 411 , 2015 , 0735-7044 ,

    초록

    The noncompetitive NMDA receptor antagonist (+)-5-methyl-10,11-dihydro-5H-dibenzo [a,d] cyclohepten-5-10-imine maleate (MK-801) has been shown to increase the probability of operant responding during extinction and reduce infralimbic prefrontal cortical activation, possibly modeling the cognitive dysfunction symptomology, and underlying cause, in patients with schizophrenia. The present study sought to determine if typical and/or atypical antipsychotics would attenuate the MK-801-induced behavioral perseveration and whether this would be associated with concomitant changes in phosphorylated ERK1/2 (pERK1/2) labeling in the infralimbic cortex (IL). Male, Long Evans rats were pretreated with the typical antipsychotic, Flupenthixol (0, 0.125, 0.25 or 0.5 mg/kg) or the atypical antipsychotic, aripiprazole (0, 0.3, 1.0, 3.0 mg/kg), then given 0.1 mg/kg MK-801 followed by a 60-min appetitive operant extinction session. Flupenthixol produced a dose-dependent decrease in MK-801-induced bar pressing behavior and locomotor activity and a dose-dependent increase in IL pERK1/2 labeling. Aripiprazole produced a U-shaped dose-response curve on MK-801-induced bar pressing behavior, a dose-dependent decrease in locomotor activity but no changes in IL pERK1/2 labeling. The attenuation of the MK-801-induced behavioral (bar pressing, locomotion) profile by Flupenthixol indicates a clear dopaminergic contribution to this behavior. The behavioral effect of aripiprazole may be due to its a) binding to presynaptic dopamine receptors at the midrange dose decreasing dopamine output and b) binding to postsynaptic dopamine receptors at the higher dose increasing dopamine tone. While both classes of antipsychotics can normalize perseverative behavioral symptoms, the underlying prefrontal cortical dysregulation seems to persist.

  6. [해외논문]   Correction to Smith et al. (2013).   SCI SCIE

    Smith, Carl D ; Piasecki, Christopher C ; Weera, Marcus ; Olszewicz, Joshua ; Lonstein, Joseph S

    Reports an error in "Noradrenergic alpha-2 receptor modulators in the ventral bed nucleus of the stria terminalis: Effects on anxiety behavior in postpartum and virgin female rats" by Carl D. Smith, Christopher C. Piasecki, Marcus Weera, Joshua Olszewicz and Joseph S. Lonstein (Behavioral Neuroscience, 2013[Aug], Vol 127[4], 582-597). Table 2 should have used the ratio of 5HIAA/serotonin - rather than the inverse - as the indicator of serotonin turnover. Using the correct ratio, differences in serotonin turnover between the postpartum and virgin females are: BSTv - 1.11 0.06 vs 0.79 0.11 (t 2.57, p 0.05); BSTd - 1.01 0.07 vs 0.68 0.11 (t 2.58, p 0.05). That is, contrary to what was originally reported, postpartum females had higher serotonin turnover in both subregions of the BST compared to virgins. The penultimate sentence in the abstract noting serotonin turnover in mothers has been corrected in the online version of this article. (The following abstract of the original article appeared in record 2013-22430-001.) Emotional hyperreactivity can inhibit maternal responsiveness in female rats and other animals. Maternal behavior in postpartum rats is disrupted by increasing norepinephrine release in the ventral bed nucleus of the stria terminalis (BSTv) with the 관2-autoreceptor antagonist, yohimbine, or the more selective 관2-autoreceptor antagonist, idazoxan (Smith et al., 2012). Because high noradrenergic activity in the BSTv can also increase anxiety-related behaviors, increased anxiety may underlie the disrupted mothering of dams given yohimbine or idazoxan. To assess this possibility, anxiety-related behaviors in an elevated plus maze were assessed in postpartum rats after administration of yohimbine or idazoxan. It was further assessed if the 관2-autoreceptor agonist clonidine (which decreases norepinephrine release) would, conversely, reduce dams' anxiety. Groups of diestrous virgins were also examined. It was found that peripheral or intra-BSTv yohimbine did increase anxiety-related behavior in postpartum females. However, BSTv infusion of idazoxan did not reproduce yohimbine's anxiogenic effects and anxiety was not reduced by peripheral or intra-BSTv clonidine. Because yohimbine is a weak 5HT1A receptor agonist, other groups of females received BSTv infusion of the 5HT1A receptor agonist 8OH-DPAT, but it did not alter their anxiety-related behavior. Lastly, levels of norepinephrine and serotonin in tissue punches from the BSTv did not differ between postpartum and diestrous rats, but serotonin turnover was higher in mothers. These results suggest that the impaired maternal behavior after BSTv infusion of yohimbine or idazoxan cannot both be readily explained by an increase in dams' anxiety, and that BSTv 관2-autoreceptor modulation alone has little influence on anxiety-related behaviors in postpartum or diestrous rats.

  7. [해외논문]   Environmental enrichment as a therapy for autism: A clinical trial replication and extension.  

    Woo, Cynthia C ; Donnelly, Joseph H ; Steinberg-Epstein, Robin ; Leon, Michael
    Behavioral neuroscience v.129 no.4 ,pp. 412 - 422 , 2015 , 0735-7044 ,

    초록

    Based on work done in animal models showing that autism-like symptoms are ameliorated following exposure to an enriched sensorimotor environment, we attempted to develop a comparable therapy for children with autism. In an initial randomized controlled trial, children with autism who received sensorimotor enrichment at home for 6 months had significant improvements in both their cognitive ability and the severity of their autism symptoms (Woo & Leon, 2013). We now report the outcomes of a similar randomized controlled trial in which children with autism, 3 to 6 years old, were randomly assigned to groups that received either daily sensorimotor enrichment, administered by their parents, along with standard care, or they received standard care alone. After 6 months, enriched children showed statistically significant gains in their IQ scores, a decline in their atypical sensory responses, and an improvement in their receptive language performance, compared to controls. Furthermore, after 6 months of enrichment therapy, 21% of the children who initially had been given an autism classification, using the Autism Diagnostic Observation Schedule, improved to the point that, although they remained on the autism spectrum, they no longer met the criteria for classic autism. None of the standard care controls reached an equivalent level of improvement. Finally, the outcome measures for children who received only a subset of sensory stimuli were similar to those receiving the full complement of enrichment exercises. Sensorimotor enrichment therapy therefore appears to be a cost-effective means of treating a range of symptoms for children with autism.

  8. [해외논문]   Strength and fine dexterity recovery profiles after a primary motor cortex insult and effect of a neuronal cell graft.   SCI SCIE

    초록

    The aim of this study was to set up (a) a large primary motor cortex (M1) lesion in rodent and (b) the conditions for evaluating a long-lasting motor deficit in order to propose a valid model to test neuronal replacement therapies aimed at improving motor deficit recovery. A mitochondrial toxin, malonate, was injected to induce extensive destruction of the forelimb M1 cortex. Three key motor functions that are usually evaluated following cerebral lesion in the clinic-strength, target reaching, and fine dexterity-were assessed in rats by 2 tests, a forelimb grip strength test and a skilled reaching task (staircase) for reaching and dexterity. The potential enhancement of postlesion recovery induced by a neuronal cell transplantation was then explored and confirmed by histological analyses. Both tests showed a severe functional impairment 2 days post lesion, however, reaching remained intact. Deficits in forelimb strength were long lasting (up to 3 months) but spontaneously recovered despite the extensive lesion size. This natural grip strength recovery could be enhanced by cell therapy. Histological analyses confirmed the presence of grafted cells 3 months postgraft and showed partial tissue reconstruction with some living neuronal cells in the graft. In contrast, fine dexterity never recovered in the staircase test even after grafting. These results suggest that cell replacement was only partially effective and that the forelimb M1 area may be a node of the sensorimotor network, where compensation from secondary pathways could account for strength recovery but recovery of forelimb fine dexterity requires extensive tissue reconstruction.

  9. [해외논문]   A role for adult hippocampal neurogenesis at multiple time scales: A study of recent and remote memory in humans.  

    D?ry, Nicolas ; Goldstein, Aaron ; Becker, Suzanna
    Behavioral neuroscience v.129 no.4 ,pp. 435 - 449 , 2015 , 0735-7044 ,

    초록

    Adult hippocampal neurogenesis (AHN) is downregulated by numerous lifestyle factors including chronic stress. While the functional significance of AHN remains elusive, computational models and empirical evidence implicate immature neurons in minimizing interference between similar memories-a process termed pattern separation. The role of neurogenesis in remote memory is less clear. Some have proposed that neurogenesis promotes the clearance of old memories from the hippocampus, while others have proposed that neurogenesis promotes long-term retention of memories within the hippocampus. We used a modified version of the behavioral pattern separation task originally described by Kirwan and Stark (2007). In this task, some objects are repeated across trials, some are similar lures and the rest are novel. Participants are asked to classify each object as old, new, or similar. The correct classification of lures as similar may tax pattern separation processes in the hippocampus and AHN. To investigate the potential role of AHN in remote memory, we introduced a 2-week delay between the presentation and recognition of certain stimuli. As in previous studies, we found that those with higher depression scores made significantly more errors at identifying lures as similar when presentation and recognition were separated by a brief delay. When presentation and recognition trials were separated by a longer delay, the correct classification of lures dropped to chance levels for all groups, but now lower stress and depression scores were associated with superior identification of exact repetitions. Our data suggest a role for AHN in the stabilization of remote memories.

  10. [해외논문]   A role of nucleus accumbens dopamine receptors in the nucleus accumbens core, but not shell, in fear prediction error.   SCI SCIE

    Li, Susan S Y ; McNally, Gavan P
    Behavioral neuroscience v.129 no.4 ,pp. 450 - 456 , 2015 , 0735-7044 ,

    초록

    Two experiments used an associative blocking design to study the role of dopamine receptors in the nucleus accumbens shell (AcbSh) and core (AcbC) in fear prediction error. Rats in the experimental groups were trained to a visual fear-conditioned stimulus (conditional stimulus [CS]) A in Stage I, whereas rats in the control groups were not. In Stage II, all rats received compound fear conditioning of the visual CSA and an auditory CSB. Rats were later tested for their fear responses to CSB. All rats received microinjections of saline or the D1-D2 receptor antagonist cis-(z)-flupenthixol prior to Stage II. These microinjections targeted either the AcbSh (Experiment 1) or the AcbC (Experiment 2). In each experiment, Stage I fear conditioning of CSA blocked fear learning to CSB. Microinjection of cis-(z)-flupenthixol (10 or 20 μg) into the AcbSh (Experiment 1) had no effect on fear learning or associative blocking. In contrast, microinjection of cis-(z)-flupenthixol (10 or 20 μg) into the AcbC (Experiment 2) attenuated blocking and so enabled fear learning to CSB. These results identify the AcbC as the critical locus for dopamine receptor contributions to fear prediction error and the associative blocking of fear learning.
