Indirect Striatal Projection Neurons Drive a D2 Receptor‐Dependent Pathway to Dyskinesia and Dystonia

open access: yesMovement Disorders, EarlyView.
D2 receptor ablation in indirect‐pathway striatal neurons reduces or abolishes dyskinetic and dystonic behaviors induced by L‐DOPA or D2 receptor agonists, respectively. Contralateral turning is reduced, while forward locomotion is increased. These effects are associated with modulation of neuronal activity in dorsal striatum and external globus ...

Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

open access: yesOikos, EarlyView.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception
