[P200 parameters in patients with diabetes mellitus type 2 (DM2)].

Introduction: A complication underserved in diabetic patients is the cognitive deficits that can reach dementia. Studying the association between electrophysiological, neuropsychological, and biochemical measures could provide a breakthrough in the understanding of this phenomenon.

Objectives: To compare P200 parameters between subjects with and without diabetes mellitus type 2 and to determine their relationship with biochemical and neuropsychological indicators.

[Optical coherence tomography and visual evoked potentials in patients with type 2 diabetes with and without retinopathy: preliminary report].

Introduction: Diabetic retinopathy remains the leading visual complication of diabetes mellitus type 2 (DM2) in productive patients. It evolves from a non-proliferative stage, occasionally asymptomatic, until a proliferative phase with neovascularization, retinal detachment and blindness. There are many reports that compare visual, biochemical or electrophysiological parameters among diabetic patients and healthy controls.

Involving the cerebellum in cocaine-induced memory: pattern of cFos expression in mice trained to acquire conditioned preference for cocaine.

Because of its primary role in drug-seeking, consumption and addictive behaviour, there is a growing interest in identifying the neural circuits and molecular mechanisms underlying the formation, maintenance and retrieval of drug-related memories. Human studies, which focused on neuronal systems that store and control drug-conditioned memories, have found cerebellar activations during the retrieval of drug-associated cue memory. However, at the pre-clinical level, almost no attention has been paid to a possible role of the cerebellum in drug-related memories.
