Mashup Score: 158State and rate-of-change encoding in parallel mesoaccumbal dopamine pathways - Nature Neuroscience - 11 month(s) ago
de Jong et al. identify two dopamine cell subtypes with sustained or transient activity patterns in both cell bodies and axon terminals. They propose that these subtypes represent the parallel encoding of a behavioral state and its temporal dynamics.

Mashup Score: 8Dopamine facilitates the translation of physical exertion into assessments of effort - npj Parkinson's Disease - 2 year(s) ago
Our assessments of effort are critically shaped by experiences of exertion. However, it is unclear how the nervous system transforms physical exertion into assessments of effort. Availability of the neuromodulator dopamine influences features of motor performance and effort-based decision-making. To test dopamine’s role in the translation of effortful exertion into assessments of effort, we had…
