In both experiments analyses for all behavioural tasks were initially carried out to examine whether behaviour differed between rats with bilateral and unilateral lesions.
Although we recorded all behavioural patterns in both studies, presented data are limited to stereotypic behaviours.
All behavioural evidence pointed that way.
Twin, family and adoption studies have been around a long time and provide a very consistent message – almost all behavioural characteristics, including mental health outcomes, are heritable to a greater or lesser degree: genetics and environment working in concert.
The family has to bear the AD symptoms: cognitive symptoms and above all, behavioural and psychological symptoms.
For all behavioural as well as electrophysiological experiments the same visual stimuli were used.
All behavioural testing occurred during the dark phase of the light dark cycle.
Repeated measures ANOVA followed by Tukey or Bonferroni post-hoc analysis where appropriate (SPSS+), was used to analyse all behavioural data, including EMG studies.
Given these limitations, and given the fact that all behavioural data is self-reported, causal inferences have to be drawn with caution.
All behavioural data were analysed using SAS 9.1.
All behavioural variable definitions were identical to previous reports.
