The collective activity of a population of neurons, beyond the properties of individual cells, is
crucial for many brain functions. A fundamental question is how activity correlations between …

A key question in systems neuroscience is to identify how sensory stimuli are represented in
neuronal activity, and how the activity of sensory neurons in turn is “read out” by downstream …

While offering high-precision control of neural circuits, optogenetics is hampered by the
necessity to implant fiber-optic waveguides in order to deliver photons to genetically …

Tactile shape recognition requires the perception of object surface angles. We investigate
how neural representations of object angles are constructed from sensory input and how …

Our sensory receptors are faced with an onslaught of different environmental inputs. Each
sensory event or encounter with an object involves a distinct combination of physical energy …

Perceptual decision making is an active process where animals move their sense organs to
extract task-relevant information. To investigate how the brain translates sensory input into …

Although the processing of whisker deflections in the barrel area of the rodent primary
somatosensory cortex (S1) has been studied extensively, how cutaneous vibro-tactile stimuli …

Limb loss and spinal cord injury are two debilitating conditions that continue to grow in
prevalence. Prosthetic limbs and limb reanimation present two ways of providing affected …

SYNGAP1 haploinsufficiency in humans leads to severe neurodevelopmental disorders
characterized by intellectual disability, autism, epilepsy, and sensory processing deficits …

Active haptic sensation is critical for object identification, but its neural circuit basis is poorly
understood. We combined optogenetics, two-photon imaging, and high-speed behavioral …
