“It is like riding a bike.” This phrase refers to memory retention of a learned task in the absence of practice. Our everyday experience shows that the nervous system forms long-term motor memories. However, experimental demonstration of how motor memories are formed and retained remains elusive.

Spinal circuit plasticity for motor control and learning

Spinal circuits are at the heart of sensorimotor transformation to generate movements. Yet, it is challenging to disentangle how spinal circuits might contribute to motor skill acquisition and retention due to the physical continuum of the brain that also participates in those processes. As such, we know little about the identities of spinal neurons or circuits that underlie the bottom-up mechanisms of motor skill learning and retention. Our recent work suggests the exciting possibility that specific cell types and circuits drive mechanisms regulating spinal learning and memory recall. We aim to understand circuit organization principles and functions that underlie motor adaptation and retention mediated by spinal circuits.

Motor control by sensory feedback

We are interested in understanding how sensory feedback regulates motor planning, learning, and execution. In this context, the lab focuses on dissecting how somatosensory, proprioceptive, and visual feedback is disseminated once the primary afferents enter the nervous system and are integrated to alter repetitive and complex motor behavior at the different hierarchical levels of the central nervous system.

A multidisciplinary approach

We use a wide variety of methods, including detailed motor kinematic assessments, mouse genetics, viral tracing and manipulation, in vitro and in vivo electrophysiological recordings in awake behaving animals, and imaging techniques. This combinatorial approach allows us to study and alter functions of specific neuronal populations, which in turn helps us to understand their roles in sensory information processing necessary for motor output and plasticity.
