Morphological Changes in Direct Pathway Striatal Neurons in a Rat Model of Tardive Dyskinesia

open access: yesMovement Disorders, EarlyView.
Abstract Background Tardive dyskinesia (TD) and drug‐induced parkinsonism (DIP) arise from prolonged dopamine antagonist use. Although D2 receptor hypersensitivity in the indirect pathway is a proposed mechanism, the role of the direct pathway remains unclear.

The stone tools of capuchins (Cebus apella) [PDF]

open access: yesInternational Journal of Primatology, 1995
We examined the production of stone took by capuchins (Cebus apella). Eleven subjects used five reduction techniques to produce 346 stone tools (48 cores and 298 flakes). They produced a sharp edge on 83% of the cores and largest flakes. Three monkeys later used a sample of these objects as cutting tools.
