Differential dopaminergic modulation of neostriatal synaptic connections of striatopallidal axon collaterals.

13 Jul 2009 Recent studies have demonstrated that GABAergic synaptic transmission among neostriatal spiny projection neurons (SPNs) is strongly modulated by dopamine with individual connections exhibiting either D(1) receptor (D(1)R)-mediated facilitation or ... Read more...

Calcium-activated SK channels influence voltage-gated ion channels to determine the precision of firing in globus pallidus neurons.

29 Jun 2009 Globus pallidus (GP) neurons fire rhythmically in the absence of synaptic input, suggesting that they may encode their inputs as changes in the phase of their rhythmic firing. Action potential afterhyperpolarization (AHP) enhances precision of ... Read more...

Sparse but selective and potent synaptic transmission from the globus pallidus to the subthalamic nucleus.

18 May 2009 The reciprocally connected GABAergic globus pallidus (GP)-glutamatergic subthalamic nucleus (STN) network is critical for voluntary movement and an important site of dysfunction in movement disorders such as Parkinson's disease. Although the GP is a ... Read more...
