Golgi cells are the principal inhibitory neurons at the input stage of the cerebellum, providing feedforward and feedback inhibition through mossy fiber and parallel fiber synapses. In vivo studies have shown that Golgi cell activity is regulated by climbing fiber stimulation, yet there is little functional or anatomical evidence for synapses between climbing fibers and Golgi cells. Here, we show that glutamate released from climbing fibers activates ionotropic and metabotropic receptors on Golgi cells through spillover-mediated transmission. The interplay of excitatory and inhibitory conductances provides flexible control over Golgi cell spiking, allowing either excitation or a biphasic sequence of excitation and inhibition following single climbing fiber stimulation. Together with prior studies of spillover transmission to molecular layer interneurons, these results reveal that climbing fibers exert control over inhibition at both the input and output layers of the cerebellar cortex.

Repeated pairing of an auditory conditioned stimulus with a weak visual unconditioned stimulus produced extended image sequences and visual responses conditioned to the tone alone. The experiment is set into the context of Pavlov's view of Helmholtz's “unconscious inference” thus providing experimental evidence linking the higher mental process of perception with classical conditioning.

Social facilitation theory states that an audience functions as a conditioned stimulus for generalized drive and that this drive effect is learned through classical conditioning. In the present study an attempt was made to condition classically an aversive drive to an audience by having a subject fail a task in front of an audience. A sample of 61 subjects took part in a 2 × 2 factorial design. Half of the subjects did not perform a first task but only a complex motor task. Half of these subjects performed in the presence of an audience, half without an audience present. Of those subjects exposed to failure on the first task, half performed a second complex motor task in the presence of the same audience. Results indicated that performance of subjects who failed a first task in the presence of an audience and then performed the second task in the presence of that audience was significantly poorer than all of the other groups. The findings were taken as evidence that the social facilitation effect may be based on an aversive learned drive.
