This analysis was used to differentiate correlated activity resulting from common response to movement from spontaneous co-activation and thus characterize the network activity and separate it from the activity of single neurons.
Previous neurophysiological studies have suggested that the encoding of movement in the parkinsonian state involves correlated activity and synchronized firing patterns.
(A ) Neurons within clusters show within-group, correlated activity.
As with pre-conv assemblies, constituent neurons showed highly correlated activity during the response.
We speculated that if the PCA neurons facilitate sperm release, then the gubernaculum muscles and the PCA might display correlated activity.
Dim backgrounds increased presynaptic release (C ) but decreased correlated activity in neighboring A17 amacrine cells (D and E ; p = 0.0053 for change relative to dark, n = 8 pairs).
Von der Malsburg [ 9, 10] argued that highly correlated activity, i.e., synchrony of firing across these shape components, is essential to that process.
Together, these studies indicate that neurons and MCs exhibit correlated activity during a critical period of retinal maturation that is enabled by neurotransmitter spillover from retinal synapses.
Cross-sectional studies investigating the role of physical activity on QoL in persons with MS have typically correlated activity levels and QoL scores [ 7, 55].
Bath application of the mGluR6 agonist APB suppressed synaptic input and eliminated correlated activity in On alpha-Off sustained RGC pairs.
