Both surface luminance and edge contrast of an object are essential features for object identification. However, cortical processing of surface luminance remains unclear. In this study, we aim to understand how the primary visual cortex (V1) processes su
The signal processing in somatosensory pathways for dynamic context-specific decoding of tactile afferent messages needs to be better understood, as does the role of the descending control of these pathways. Abstract During object manipulation tasks, the brain selects and implements action-phase ...

Thus, it is now possible to develop novel functional artificial intelligence models to study the encoding and decoding of natural scenes by analyzing the spiking responses of retinal ganglion cells. In this paper, we review some of the recent progress that has been achieved in this field. Most ...
in the present neuroanatomical study, we attempted to pave the way toward a better understanding of the tinnitus syndrome, and compared two groups of almost perfectly matched individuals with (TIHL) and without (NTHL) pure-tone tinnitus, but both characterized by pure-tone hearing loss. The two...
to quantify the impact of cross-neuronal correlations in population activity [15–19] and have applied them to the study of population coding across various sensory modalities [20–22]. Another application of information theory to neuroscience is the measure of causal information transfer [23] to...
Semantic Granularity: successful universal representation should encompass a range of semantic details, from broad captions to intricate descriptions, facilitating diverse applications. (All images from now on, except those in the coding section, are from the original Florence-2article) ...
Therefore, we tested GNWT’s central claim concerning the necessity of prefrontal cortex (PFC) in the hypothesized broadcasting of information via decoding of visual content and synchronization between PFC and high-level visual areas in the occipital-temporal cortex. We focused specifically on PFC, ...
Coding efficiency was suggested to be a major organizing principle in the nervous system3,4. Consequently, a tractable problem that has been studied extensively in theoretical neuroscience is the nature of optimal coding of a one-dimensional stimulus5,6,7,8,9,10,11,12. However, despite the ...
