fMRI is generally thought to be no more or less reliable than the traditional polygraph test, which measures the changes in various physiological parameters — such as heart rate, blood pressure and skin conductance — that can change when someone is lying.

Roukes says researchers learned about «the granularity of nature at the nanoscale,» where processes that are continuous at larger sales (such as electrical and heat conductance) are no longer so, and «quantum effects become dramatically manifest.»

The asymmetry of the Vj response of these UNC - 7: UNC - 9 heterotypic channels was not restricted to the steady state response of these cells, but also was seen in the rectifying nature of the initial conductance that increases as the UNC - 9 cell becomes more positive.

The main results can be summarized as follows: (1) Synchrony during early mother - child interactions has neurophysiological correlates [85] as evidenced though the study of vagal tone [78], cortisol levels [80], and skin conductance [79]; (2) Synchrony impacts infant's cognitive processing [64], school adjustment [86], learning of word - object relations [87], naming of object wholes more than object parts [88]; and IQ [67], [89]; (3) Synchrony is correlated with and / or predicts better adaptation overall (e.g., the capacity for empathy in adolescence [89]; symbolic play and internal state speech [77]; the relation between mind - related comments and attachment security [90], [91]; and mutual initiation and mutual compliance [74], [92]-RRB-; (3) Lack of synchrony is related to at risk individuals and / or temperamental difficulties such as home observation in identifying problem dyads [93], as well as mother - reported internalizing behaviors [94]; (4) Synchrony has been observable within several behavioral or sensorial modalities: smile strength and eye constriction [52]; tonal and temporal analysis of vocal interactions [95](although, the association between vocal interactions and synchrony differs between immigrant (lower synchrony) and non-immigrant groups [84]-RRB-; mutual gaze [96]; and coordinated movements [37]; (5) Each partner (including the infant) appears to play a role in restoring synchrony during interactions: children have coping behaviors for repairing interactive mismatches [97]; and infants are able to communicate intent and to respond to the intent expressed by the mother at the age of 2 months [98].
