Topic: neuronal representations

Liset M de la Prida is a Physicist (1994) and PhD in Neuroscience (1998), who leads the Laboratorio de Circuitos Neuronales at the Instituto Cajal, Madrid, Spain (http://www.hippo-circuitlab.es). The main focus of her lab is to understand the function of the hippocampal circuits in the normal and the diseased brain, in particular oscillations and neuronal representations. She is a leading international expert in the study of the basic mechanisms of physiological ripples and epileptic fast ripples, with strong visibility as developer of novel groundbreaking electrophysiological tools.

Animals experience the world as a continuous sequence of complex high-dimensional sensory stimuli. They need to build internal models from this ongoing stream of experiences with few supervisory and reinforcement signals. How they accomplish this feat remains unclear. One possibility is that the brain relies on a slowness objective (SO) which stipulates that neuronal representations change little over time$^1$. This allows extracting slowly varying underlying factors from the sensory experience, in some cases, with local plasticity rules$^2$. However, the approach precludes exploiting the rich
