Bidirectional plasticity at developing climbing fiber–Purkinje neuron synapses

European Journal of Neuroscience, 2008
AbstractClimbing fibers provide one of the two major excitatory inputs to the cerebellar cortex. In an immature animal, several climbing fibers form synapses with one Purkinje neuron. During postnatal development most climbing fiber innervations with a Purkinje neuron are eliminated and only one strong fiber remains.

Inhibition of cerebellar Purkinje cells by climbing fiber input

Pfl�gers Archiv European Journal of Physiology, 1972
The inhibitory effects of the climbing fiber input on cerebellar Purkinje cells was studied in cats. 1. The excitatory and the inhibitory effect of the CF input was observed independent from each other. 2. At C-T intervals longer than 20 msec the EPSP of the Purkinje cell produced by CF activation was reduced by a preceding inferior ...

Laser axotomy on cerebella climbing fibers

2011
In the adult nervous system, different population of neurons corresponds to different regenerative behavior. Although previous works show that olivocerebellar fibers are capable of axonal regeneration in a suitable environment as a response to injury [1], we have hitherto no details about the real dynamics of fiber regeneration.

Organization and remodeling of the olivocerebellar climbing fiber projection

The Cerebellum, 2006
Climbing fibers, terminal portions of the axons of inferior olive neurons, form strong synaptic connections to Purkinje cells in an exclusive one-to-one relationship. This projection is established during development by drastic reshaping in each climbing fiber and in overall axonal arborization.

Latencies of Climbing Fiber Inputs to Turtle Cerebellar Cortex

Journal of Neurophysiology, 2005
Responses of separate regions of rat cerebellar cortex (Cb) to inferior olive (IO) stimulation occur with the same latency despite large differences in climbing fiber (CF) lengths. Here, the olivocerebellar path of turtle was studied because its Cb is an unfoliated sheet on which measurements of latency and CF length can be made directly across its ...

Cerebellar climbing fibers signal flexible, rapidly adapting reward predictions

AbstractClassical models of cerebellar computation posit that climbing fibers (CFs) operate according to supervised learning rules, correcting movements by signaling the occurrence of motor errors. However, recent findings suggest that in some behaviors, CF activity can exhibit features that resemble the instructional signals necessary for ...
