The task relied on the assumption that the visual presentation of a lexical stimulus with semantic content, insofar as it was recognized as a "real English word", would automatically activate a cluster of semantic associations whose neural correlates could be identified by the contrast words-nonwords.
Called working memory, this task relies on the prefrontal cortex via the neurotransmitter dopamine and a dopamine-degrading enzyme called catechol-O-methyltransferase (COMT).
60 On the other hand, bilateral concurrent matching is also subject to limitations of its own in that this task relies on interhemispheric communication.
Since the STD task relies on the indexing of the whole speech database, word spotting systems perform a sequential parsing of the speech stream with the purpose of detecting the targeted word sequence.
Since the ASRT task relies both on the procedural system and on statistical computations, we hypothesized that implicit sequence-specific learning would be attenuated by simultaneous sentence comprehension if the two tasks engage the same neurocognitive system(s).
The inhibitory avoidance task relies heavily on the dorsal hippocampus but also depends on the entorhinal and parietal cortex and is modulated by the amygdale [ 25, 26].
It remains unknown, therefore, to what degree the learning gains in the virtual task rely on the neural representations of familiar physical representations, which would not be observed for laboratories that involve unfamiliar materials.
It takes insights from the behaviours and coordination capabilities of social insects, where the success of a group in accomplishing a task relies heavily on the interactions among its members.
If the performance of the OR task relied on an intrinsic decrease in Schaffer collateral – CA1 synaptic efficacy (Fig. 2a), it could be hypothesized that the threshold needed to induce LTP at these synapses would be negatively affected by OR.
This task relies on conflict between the innate fear that rodents exhibit toward elevated and open areas vs. natural exploration of novel environments.
