There is an impressive scarcity of quantitative models of the clock patterns in the brain. We propose a mesoscopic approach, i.e. neither a description at single neuron level, nor at systemic level/too coarse granularity, of the time perception at the time of the saccade. This model uses functional pathway knowledge and is inspired by, and integrates, recent findings in both psychophysics and n...

UNLABELLED Our internal clock system is predominantly dopaminergic, but memory is predominantly cholinergic. Here, we examined the common sensibility encapsulated in the statement: "time goes faster as we get older". OBJECTIVE To measure a 2 min time interval, counted mentally in subjects of different age groups. METHOD 233 healthy subjects (129 women) were divided into three age groups: G1...

Perhaps the most obvious contrast in quality of timing is that between human and animal performance. In both cases considerable evidence is provided that mean times are quite accurate and that, to a first approximation anyhow, all distributions of normalized responses are the same. However, substantial differences exist between the animal and human data in the magnitude of the relative variabil...
