Whereas the conventional wisdom treats the eye as a simple prefilter for visual images, it now appears that the retina solves a diverse set of specific tasks and provides the results explicitly to downstream brain areas -Eye smarter than scientists believed: neural computations in circuits of the...
Scientists Map Nearly 200 Areas in the Human BrainNature Video
This simplistic perception was based on the presence of resident immune cells, the microglia, and barrier systems within the brain, and the assumption that the central nervous system (CNS) lacks lymphatic drainage. This view was revised with the discoveries that higher functions of the CNS, ...
The popular notions about "left brain" and "right brain" qualities are generalizations that are not well supported by evidence. However, there are some important differences between these areas. The left brain contains regions that are involved in language production and comprehension (calledBroca's ...
Knowing one’s own behavioral state has long been theorized as critical for contextualizing dynamic sensory cues and identifying appropriate future behaviors. Ascending neurons (ANs) in the motor system that project to the brain are well positioned to provide such behavioral state signals. However, wh...
areas around the lesion can substantially contribute to recovery, e.g., by the formation of new connections (“axonal sprouting”) (Granziera et al., 2007) and by taking over functions from the lesioned region (“remapping”) (Silasi and Murphy, 2014). Molecular and electrophysiological ...
BrainFit® CognitiveMAP evaluates cognitive fitness, intelligences and mindset development in the 5 core brain areas of: 1) Visual processing, which governs success in Math and visual arts; 2) Auditory processing, foundation for language learning and literacy; ...

Comprehensive integration of structural and functional connectivity data is required to model brain functions accurately. While resources for studying the structural connectivity of non-human primate brains already exist, their integration with functiona
Primary sensory regions reached peak volume earliest and showed faster post-peak declines, whereas fronto-temporal association cortical areas peaked later and showed slower post-peak declines (Fig. 2b, Supplementary Information 8.2). Notably, this spatial pattern recapitulated a gradient from sensory-to...
