Topic: Brain imaging, connectivity and assessment
The method of single-cell recording in awake behaving monkeys as they perform behavioral tasks is perhaps the most powerful approach to understanding the neural basis of behavior. In contrast to cellular analyses in vitro, e.g., in slice preparations, the in vivo approach allows direct correlation of cellular activity and specific processes as they are isolated by behavioral paradigms. As brain mechanisms are studied under natural conditions, inferences about the dynamic basis of information processing are direct. Limitations of this approach include the inability to unequivocally identify the cell under investigation, though location by cytoarchitectonic area and cortical depth is possible. Neurophysiological studies have not only given a dynamic view of neural processing "on line" but have allowed investigators to examine fundamental issues about normal brain function and dementia. Here I illustrate some of these issues and the power of single cell physiology to address them. Before doing so, it should be patently obvious that recording one cell at a time is a technical necessity and in no way should be taken to imply that any behavior is dependent on a single cell. Rather the neuron investigated is a representative of a cohort of cells acting in aggregate.

How this study scored 40/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 23 of the 58 points we could judge it on, which is 40 out of 100.
