Study TitleLong-term neural and physiological phenotyping of a single human
Study TypeLongitudinal
Study SummaryThe dynamics of human brain function are increasingly well understood at the short timescale of seconds/minutes (for example, through studies of learning) and the long timescale of years/decades (for example, through studies of development andageing), but almost nothing is known about how the human brainfunction varies across the range of days to months. This is a critical gap, because major psychiatric disorders show large fluctuations in brain function over this timescale. However, the kind of dense longitudinal phenotyping that is necessary to understand this question is extremely challenging with healthy human volunteers,who are unlikely to be sufficiently motivated to sustain frequent participation in a study over a long period. For this reason, the participation of motivated experimenters can be uniquely useful for demanding longitudinal studies. We investigated the long-range dynamics of brain function andtheir relation to a broad set of psychological and biological variables in a single healthy human (author R.A.P.) over the course of 532 days (along with several follow-up visits), representing one of the most intensive biological characterizations of a single individual ever performed (referred to hereafter as the MyConnectomestudy). The study was designed to measure the broadest possible range of human phenotypes (the phenome’3,4) to allow the widespread assessment of relations between psychological, neural and metabolic function. The results of the present study demonstrate that healthy brain function shows rich dynamics over the course of 18 months, and that these dynamics are paralleled by ongoing fluctuations in psychological and physiological function as observed in behaviour,gene expression and metabolomic measurements. These findings provide a proof of concept for the dynamic longitudinal phenotyping of individuals, which we propose will be crucial togain a better understanding of the substantial fluctuations in psychological and neural function in individuals with major psychiatric disorders.

Treatment Summary:These are samples from the same individual taken over the course of 18 months. We are interested in comparing these results to other measurements from the same individual, including RNA-seq and brain imaging.
