Integrating spatial and temporal information is essential for our sensory experience. While psychophysical evidence suggests dependencies in duration perception, few studies have directly tested the neural link between processing. Using ultra-high-field functional MRI neuronal-based modeling, we investigated how where processing representation of a visual stimulus linked to that its location. Our results show transition coding: from monotonic spatially-dependent early cortex unimodal spatially-invariant frontal cortex. Along dorsal stream, particularly intraparietal sulcus (IPS), neuronal populations common selective responses both information. In IPS, topographic organizations are also linked, although maps smaller, less clustered, more variable across participants. These findings help identify mechanisms underlying human perception characterize time space processing, highlighting importance their interactions shaping brain responses. Common organizational principles not fully understood. This study shows coding brief events transforms along cortical hierarchy, interact through representations.

Decision making frequently depends on monitoring the duration of sensory events. To determine whether, and how, perception elapsed time derives from neuronal representation stimulus itself, we recorded optogenetically modulated vibrissal somatosensory cortical activity as male rats judged vibration duration. Perceived was dilated by optogenetic excitation. A second set intensity; here, excitation amplified intensity percept, demonstrating cortex to be common gateway both feature processing. model beginning with membrane currents evoked drive culminating in perceived successfully replicated rats' choices. Time is thus deeply intermeshed within processing pathway sense touch suggesting that experience may further investigated toolbox coding.

Abstract The internal clock is a psychological model for timing behavior. According to information theory, time might be manifestation of flow during sensory processing. Herein, we tested three hypotheses: (1) whether adaptation reduces (or novelty increases) the rate (2) speed reflects amount cortical processing? (3) motion tunes speed. current study used an oddball paradigm in which participants detected duration changes while being recorded with electroencephalography (EEG). For data analysis, combined cognitive modeling neural decoding techniques. Specifically, designed Adaptive-Thought-of-Control (ACT-R) models explain human and linked them EEG features discovered through machine learning. Our results indicate that performance influenced by both non-timing factors. may reflect processing, thereby clarifying long-standing mystery.
