However, we reasoned that some aspects of ethanol's effects might better be revealed by subjecting the worms to a more complex behavioural task that relies on sensorimotor processing e.g. foraging.
If nurses' pain impression was a valid and reliable measure, a more complex behavioural scale to assess pain would become redundant.
TG rats, in addition to introducing a species with many more human-like characteristics such as postnatal brain development and a more complex behavioural repertoire [ 7], offer many distinct practical advantages over mice for neurophysiological studies in vivo, particularly for long-term recordings in longitudinal designs.
During postembryonic development, Drosophila undergoes dramatic morphological changes towards sculpting the adult fly which exhibits a much more complex behavioural repertoire compared to the larva.
However, the real problem might be that more complex behavioural phenotypes are affected by many genes, each with only a small effect accounting for only 1% or even less of the phenotypic variance [ 81], therefore inadequate statistical power is a serious problem.
In more complex behavioural systems there may be iterative and more incremental steps, and sometimes the models may take the shape of a cycle.
Therefore, they have the potential to be used in mutual and more complex behavioural interactions supporting pair formation and synchronisation as well as pair-bond maintenance, as suggested for other mutual behavioural displays (reviewed by Bradbury and Vehrencamp, 2011).
Theorists, however, suggest that impulsivity encompasses a more complex array of behavioural processes, including urgency, risk-taking, sensation-seeking, nonplanning, lack of premeditation, a disregard for future consequences and insensitivity to punishment (Barratt, 1985; Evenden, 1999; Moeller et al., 2001; Monterosso and Ainslie, 1999; Whiteside and Lynam, 2003).
An alternative approach here would be to use a more complex SSM which included behavioural switching.
Bräuer et al. (2013) therefore propose that future studies will benefit from using a more complex task that requires behavioural coordination.
This scenario is complicated when some evidences are considered, pointing to a more complex relationship than that previously thought between the immature neurons and some behavioural paradigms.
