Editing Putamen (section)

===Reinforcement and implicit learning===
Along with various types of movement, the putamen also affects reinforcement learning and [[implicit learning]].<ref name="Mark">{{cite journal | journal = Annu Rev Neurosci | year = 2002| volume = 25 | issue =  1| pages = 563–93 | title = Learning and memory functions of the Basal Ganglia | author = Packard MG |author2=Knowlton BJ  | pmid = 12052921 | doi =10.1146/annurev.neuro.25.112701.142937 }}</ref>

[[Reinforcement learning]] is interacting with the environment and catering actions to maximize the outcome. Implicit learning is a passive process where people are exposed to information and acquire knowledge through exposure. Although the exact mechanisms are not known, it is clear that dopamine and tonically active neurons play a key role here. Tonically active neurons are [[cholinergic]] [[interneurons]] that fire during the entire duration of the stimulus and fire at about 0.5–3 impulses per second. Phasic neurons are the opposite and only fire an action potential when movement occurs.<ref name="Yamada">{{cite journal | journal = Journal of Neuroscience | date = April 7, 2004 | volume = 24 | issue = 14 | pages = 3500–10 | title = Tonically active neurons in the primate caudate nucleus and putamen differentially encode instructed motivational outcomes of action | author = Yamada H |author2=Matsumoto N |author3=Kimura M  | pmid = 15071097 | doi =10.1523/JNEUROSCI.0068-04.2004 | pmc = 6729748 | doi-access = free }}</ref>
