Validation of decision-making models and analysis of decision variables in the rat basal ganglia.

3 Aug 2009 Reinforcement learning theory plays a key role in understanding the behavioral and neural mechanisms of choice behavior in animals and humans. Especially, intermediate variables of learning models estimated from behavioral data, such as the ...

Increased Fos expression among midbrain dopaminergic cell groups during birdsong tutoring.

Aug 2009 During avian vocal learning, birds memorize conspecific song patterns and then use auditory feedback to match their vocal output to this acquired template. Some models of song learning posit that during tutoring, conspecific visual, social and/or ...

Repeated learning makes cultural evolution unique.

Aug 2009 Although genetic information is acquired only once, cultural information can be both abandoned and reacquired during an individual's lifetime. Therefore, cultural evolution will be determined not only by cultural traits' ability to spread but also ...

[Effect of the level of stimulus awareness on expectancy learning]

30 Jul 2009 The purpose of this experiment was to study the effects of the level of awareness of the stimuli on expectancy learning. Nine-two participants received repeated presentations of two stimulus sequences (E1A-->E2A and E1B-->E2B), E1 being a masked ...

[Influence of group learning in search processes]

30 Jul 2009 Our decisions about the world are often based on a sequential analysis of various uncertain cues. To achieve high accuracy, the order in which these cues are searched is crucial. Previous research, however, has shown that people demonstrate slow ...

The rat prelimbic cortex mediates inhibitory response control but not the consolidation of instrumental learning.

30 Jul 2009 The potential role of the prelimbic cortex of the rat in the acquisition of instrumental responding is currently uncertain. In addition, modeling the acquisition of Pavlovian and spatial conditioning tasks has suggested that the process of ...

Individual differences in skilled reaching for food related to increased number of gestures: evidence for goal and habit learning of skilled reaching.

30 Jul 2009 Skilled reaching in rodents and primate is motorically similar, but success in reaching by rodents is distinctively variable. The source of this variability has not been examined previously. Long-Evans rats were videotaped as they reached for food ...

Role of acetylcholine in negative patterning in turtles (Chrysemys picta).

30 Jul 2009 Turtles were run on a negative patterning task involving 2 positive elements, a key with white stripes on a black background, and a solid red key, and a compound stimulus combining the 2 elements, white stripes on a red background. Injections of ...

Boosting cholinergic activity in gustatory cortex enhances the salience of a familiar conditioned stimulus in taste aversion learning.

30 Jul 2009 The cholinergic system is important for learning, memory, and responses to novel stimuli. Exposure to novel, but not familiar, tastes increases extracellular acetylcholine (ACh) levels in insular cortex (IC). To further examine whether cholinergic ...

Elemental and configural processing of odour mixtures in the newborn rabbit.

30 Jul 2009 The processing of odour mixtures by young organisms is poorly understood. Recently, the perception of an AB mixture, known to engage configural perception in adult humans, was suggested also to be partially configural in newborn rabbits. In ...
