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...
"These differentparts of the brainall have separate functions and speakdifferent languageswhen referring to the location of objects around us," Saalmann says. "But our study shows that these brain areas are connected by information channels that allow us to manipulate objects. So we have to thi...
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, ...
Pale blue areas signal the occurrence of stimulation when SB is present. On top of graph, expanded traces to illustrate SB uptake (black lines; scale bar: 0.05 a.u. vs. 2 min) from 4 out of the 18 boutons (indicated by white arrowheads in e, GZ), and its rate (green lines...
Neuroimaging techniques can especially be useful for mapping different functions to anatomical regions in the eloquent cortex at the subject level. 2. Materials and Methods The ultimate aim of this review is to explore the active areas of the brain in BCI while using fMRI, fNIRS, EEG, and ...
Related:What's the difference between the right brain and the left brain? 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 regi...
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 ...
isolated areas of heightened activity. This classical approach rests on the assumption that focal loci represent discrete brain regions putatively engaged by the stimulus and that subthreshold activity in other regions is of negligible interest. The surprisingly long-wavelength content of task-activation ...
The study is an example of how the application of artificial neural networks, or A.I., are enabling researchers to unlock the extremely complex signaling in the brain that underlies functions such as processing language. The researchers gather brain activity data from study participants who read se...
The human extrastriate visual cortex comprises numerous functionally defined areas, which are not identified in the widely used cytoarchitectonical map of
