Extra-dimensional versus intra-dimensional set shifting performance following frontal lobe excisions, temporal lobe excisions or amygdalo-hippocampectomy in man
Attentional “set” shifting was assessed in a group of 20 neurosurgical patients with localized
excisions of the frontal lobes, a group of 20 patients with unilateral temporal lobe lesions …

Serotoninergic regulation of emotional and behavioural control processes
5-Hydroxytryptamine (5-HT, serotonin) has long been implicated in a wide variety of emotional,
cognitive and behavioural control processes. However, its precise contribution is still not …
