Activity of striatal neurons reflects dynamic encoding and recoding of procedural memories

Article Abstract:

Long-term recordings from multiple neurons in the sensorimotor striatum, a basal ganglia structure implicated in habit formation, are made to identify neural mechanisms that might underlie such learning dynamics. The changes in task representation in cortico-basal ganglia circuits represent neural equivalents of the explore-exploit behavior characteristic of habit learning.

Neurons compute internal models of the physical laws of motion

Article Abstract:

Cerebellar and brainstem motion-sensitive neurons that compute a solution to the inertial motion detection problem are identified by using new stimulus combinations. The firing rates of these populations of neurons reflect the computations necessary to construct an internal model representation of the physical equations of motion.

Lateral habenula as a source of negative reward signals in dopamine neurons

Article Abstract:

The study of which brain parts provide signals to dopamine neurons for reward-seeking behavior revealed that inhibitory input by lateral habenula plays an important role.
