Transfer of learning after updating training mediated by the striatum
Neuroimaging studies in humans have recently begun to suggest the existence of a small group of specific brain sites that appear to encode the subjective values of different types of rewards on a neural common scale,…Volume 22, Issue 6, 01 December 2012, Pp 1027-1038Dino J. Glimcher Updating dopamine reward signals Recent work has advanced our knowledge of phasic dopamine reward prediction error signals.The Current Opinion journals were developed out of the recognition that it is increasingly difficult for specialists to keep up to date with the expanding volume of information published in their subject.Elsevier’s Current Opinion journals comprise of 26 leading titles in life sciences and adjacent fields.How do humans make choices between different types of rewards?Economists have long argued on theoretical grounds that humans typically make these choices as if the values of the options they consider have been mapped to a single common scale for comparison.

Seth Brain networks underlying episodic memory retrieval The importance of the medial temporal lobe to episodic memory has been recognized for decades.
Recent human f MRI findings have begun to delineate the functional roles of different MTL regions, most notably the hippocampus, for the retrieval of episodic memories.
How neuronal activity modifies the morphology of the spine and how these modifications affect synaptic transmission and plasticity are intriguing issues.
Indeed, the induction of long-term potentiation (LTP) or depression (LTD) is associated…
