Open AccessInduction of altered states of consciousness during Floatation-REST is associated with the dissolution of body boundaries and the distortion of subjective time
Floatation-REST (Reduced Environmental Stimulation Therapy) minimizes stimulation of the nervous system by immersing subjects in an environment without sound or light while they effortlessly float in thermoneu...

Dynamics of retrospective timing: A big data approach
Most interval timing research has focused on prospective timing tasks, in which participants are explicitly asked to pay attention to time as they are tested over multiple trials. Our current understanding of ...

Open AccessPlacebo effects on nausea and motion sickness are resistant to experimentally-induced stress
Nausea often occurs in stressful situations, such as chemotherapy or surgery. Clinically relevant placebo effects in nausea have been demonstrated, but it remains unclear whether stress has an impact on these ...

Open AccessMindfulness Meditation Influences Implicit but Not Explicit Coding of Temporal Simultaneity
In the meditative state time appears to slow down and in the present moment it expands. However, to date, there is no investigation of the effect of meditative state on the structure of the “psychological mome...

The phenomenology and cognitive neuroscience of experienced temporality
We discuss the three dominant models of the phenomenological literature pertaining to temporal consciousness, namely the cinematic, the retentional, and the extensional model. This is first done by presenting ...

Attenuated Insular Processing During Risk Predicts Relapse in Early Abstinent Methamphetamine-Dependent Individuals
There is some evidence that neuroimaging can be used to predict relapse among abstinent methamphetamine-dependent (MD) individuals. However, it remains unclear what cognitive and neural processes contribute to...

Spontaneous EEG fluctuations determine the readiness potential: is preconscious brain activation a preparation process to move?
It has been repeatedly shown that specific brain activity related to planning movement develops before the conscious intention to act. This empirical finding strongly challenges the notion of free will. Here, ...

The inner sense of time: how the brain creates a representation of duration
The neural mechanisms underlying the perception of duration have proved difficult to unravel and remain unclear. Here, Wittmann explores why this has been the case and presents recent theoretical developments ...

Time and decision making: differential contribution of the posterior insular cortex and the striatum during a delay discounting task
Delay discounting refers to the fact that an immediate reward is valued more than the same reward if it occurs some time in the future. To examine the neural substrates underlying this process, we studied 13 h...

Effects of working permanent night shifts and two shifts on cognitive and psychomotor performance
Objectives: The study aimed to clarify whether cognitive and psychomotor performance, which are important for occupational and traffic safety, are impaired by working permanent night shifts (NSs) compared with ea...
