Neural timing signal for precise tactile timing judgments.
The brain can precisely encode the temporal relationship between tactile inputs. While behavioural studies have demonstrated precise interfinger temporal judgments, the underlying neural mechanism remains unknown. Computationally, two kinds of neural responses can act as the information source. One is the phase-locked response to the phase of relatively slow inputs, and the other is the respons...
متن کاملNeural mechanisms of timing.
A crucial step in timing research is to isolate clock components from other sources of temporal variability. Significant progress has been made both behaviorally and neurologically, using elaborate experimental designs that separate timing mechanisms from motoric sensory and mnemonic processes. Marked similarities between the temporal characteristics of the clock in perception and production ta...
متن کاملSomatosensory saccades reveal the timing of tactile spatial remapping.
Remapping tactile events from skin to external space is an essential process for human behaviour. It allows us to refer tactile sensations to their actual externally based location, by combining anatomically based somatosensory information with proprioceptive information about the current body posture. We examined the time course of tactile remapping by recording speeded saccadic responses to s...
متن کاملNeural coding of tactile texture: comparison of spatial and temporal mechanisms for roughness perception.
A previous study showed that roughness perception may depend on either temporal or spatial variations in firing rate among cutaneous mechanoreceptive afferents. The present study was designed to distinguish between these hypotheses. Plastic surfaces embossed with patterns of dots designed to produce predictable alterations in temporal and spatial firing rate variation were used as stimuli in ps...
متن کاملNeural mechanisms for spatial computation
Locating oneself within an environment, remembering goal locations and planning routes are fundamental cognitive functions (Wolbers & Hegarty, 2010). Profound insights into the mechanisms for these cognitive abilities have come from the discovery of neurons in the hippocampus and entorhinal cortex with spatial firing properties. These neurons, which include place cells (O’Keefe, 1976), head dir...
