Brain histamine depletion enhances the behavioural sequences complexity of mice tested in the open-field: Partial reversal effect of the dopamine D2/D3 antagonist sulpiride
A role of mouse brain histamine on the temporal architecture of behaviour is proposed. Descriptive and t-pattern analyses in the open field were carried out in the study. Histamine deficient mice had a marked increase in exploratory t-patterns complexity. D2/D3 antagonism partially reverted the arrangement of exploratory t-patterns.
