Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).
Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.
Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.
Dopamine signals in the ventral, dorsomedial, and dorsolateral striatum are modulated by various variables, such as stimulus-associated value, choice, confidence, but these modulations can be inclusively explained by TD errors.
Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.
Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.
