Brief history

Neuroscience group was constituted starting from a joint research work between Ana Lía Albarracín, PhD. and Fernando Farfán, PhD. Their studies were around temporal analysis of afferent activity in vibrissal system, which gave rise to new research lines that cemented the group’s formation. By 2012, the Neuroscience group is established in the LAMEIN, led by Farfán, which begin their studies in Biomimetics of sensory systems, computational neuroscience, electrophysiology, and brain computer interface for control and treatment of Parkinson’s disease.

Research

Peripheral neural encoding at vibrissal system. We are interested in knowing how acquires, encodes and send the texture information from whiskers to brain.

Biomimetics. We study the mechanical aspects involved in tactile interaction between whiskers and rough surfaces occurring during exploratory behavior of rats. We use computational models and we evaluate its possibilities for technological development.

Neural encoding of visual information. We are interested in knowing how acquires, encodes and send the visual information from retina to visual cortex. Our studies are directed at electrical stimulations of sensorial pathway to restore the visual perception.

Dynamic EMG processing. We study the myoelectric activity evoked by dynamic contractions (movements with different kinematic characteristics). Our studies are directed at muscular efficiency quantification.

Treatment and characterization of Parkinson disease. We seek to optimize and automate the procedures for release of dopamine and we evaluate their electrophysiological effects in Parkinson’s disease models.
