Stimulus specific deficit on visual reversal learning after lesions of medial prefrontal cortex in the mouse.

9 Oct 2007 Tests of executive abilities, such as discrimination reversal and attentional set shifting, are sensitive to prefrontal cortex (PFC) damage in primates. The purpose of the present study was to use a primate reversal task to determine if PFC in the ...

Separate movement planning and spatial assimilation effects in sequential bimanual aiming movements.

29 Sep 2007 This study extended earlier work by showing spatial assimilations in sequential bimanual aiming movements when the participant preplanned only the first movement of a two-movement sequence. Right-handed participants (n=20, aged 18 to 22 years) made ...

Latent timing in human conditioned avoidance.

29 Sep 2007 Four experiments explored signal timing in human conditioned avoidance. Participants received discrimination training with different duration signals that announced the outcome (S+) or not (S-). Temporal discrimination and superposition of ...

Altered performance of reelin-receptor ApoER2 deficient mice on spatial tasks using the Barnes maze.

29 Sep 2007 The apolipoprotein E receptor 2 (ApoER2), expressed predominantly in forebrain regions including the hippocampus, is 1 of 2 receptors for the extracellular matrix protein reelin, which is critical for cortical development. Previous studies of ApoER2 ...

Medial prefrontal serotonin in the rat is involved in goal-directed behaviour when affect guides decision making.

13 Sep 2007 RATIONALE: Across species, serotonin (5-HT) depletion in the prefrontal cortex (PFC) has been shown to cause impaired performance on tests of cognitive flexibility and the processing of affective information (e.g. information with an 'emotional' ...

Attentional switching in the sequential flanker task: age, location, and time course effects.

12 Sep 2007 The sequential flanker task was developed to study sequential performance using methodology borrowed from studies of task switching. We investigated age differences in backward inhibition [BI: Mayr, U., & Keele, S. W. (2000). Changing internal ...

The contribution of ventrolateral and dorsolateral prefrontal cortex to response reversal.

2 Sep 2007 Studies investigating response reversal consistently implicate regions of medial and lateral prefrontal cortex when reinforcement contingencies change. However, it is unclear from these studies how these regions give rise to the individual ...

Lesions of the basal forebrain impair reversal learning but not shifting of attentional set in rats.

2 Sep 2007 The cholinergic neurons of the basal forebrain, which project to cortex, the thalamic reticular nucleus and the amygdala, are implicated in many aspects of attentional function, while the intrinsic neurons of the basal forebrain are implicated in ...

A derived transfer of functions and the implicit association test.

30 Aug 2007 Participants were trained in a series of interrelated conditional discriminations that aimed to establish four 4-member equivalence classes (i.e., A1-B1-C1-D1, A2-B2-C2-D2, A3-B3-C3-D3, A4-B4-C4-D4). During this training, the four A stimuli (i.e., ...

Transformation of avoidance response functions in accordance with same and opposite relational frames.

30 Aug 2007 Research on the emergence of human avoidance behavior in the absence of direct contact with an aversive event is somewhat limited. Consistent with work on derived relational responding, the present study sought to investigate the transformation of ...
