The cerebellum has already been shown to participate in the navigation function. We propose here that this structure is involved in maintaining a sense of direction and location during self-motion by monitoring sensory information and interacting with navigation circuits to update the mental representation of space. To better understand the processing(More)
Early investigations of cerebellar function focused on motor learning, in particular on eyeblink conditioning and adaptation of the vestibulo-ocular reflex, and led to the general view that cerebellar long-term depression (LTD) at parallel fiber (PF)-Purkinje cell (PC) synapses is the neural correlate of cerebellar motor learning. Thereafter, while the full(More)
Associative olfactory learning increased survival of adult born granule interneurons in the olfactory bulb (OB) at regions which are specific to the learned odorant. However, the mechanism shaping this odor-specific distribution of newborn neurons and its temporal relationship with the learning process are unknown. In the present study, using(More)
The contribution of the cerebellum to the non-motor aspects of spatial navigation is now established, but the mechanisms of its participation remain unclear. The L7-PKCI mouse model, in which inhibited PKC activity suppresses parallel fiber-Purkinje cell long-term depression (LTD), provides the opportunity to study their spatial abilities in the absence of(More)
Spatial navigation calls upon mnemonic capabilities (e.g. remembering the location of a rewarding site) as well as adaptive motor control (e.g. fine tuning of the trajectory according to the ongoing sensory context). To study this complex process by means of behavioral measurements it is necessary to quantify a large set of meaningful parameters on multiple(More)
