TL;DR: Responses evoked in the cerebellar cortex following stimulation of caudate nucleus are described in 1.1.
Abstract: 1. Responses evoked in the cerebellar cortex following stimulation of caudate nucleus are described.
2. The evoked responses recorded from the surface of the cerebellar cortex were found to be of two types, one with a short (4-6 msec) latency and one with a longer (12-17 msec) latency.
3. The short latency response was maximal in the lobulus simplex, the longer latency response was maximal in paramedian lobule.
4. Following lesions in the inferior olive the longer latency response was absent.
5. Recordings from within the cerebellar cortex showed that the short latency response was uniformly distributed throughout the grey matter, the longer latency response was maximal in the region of the Purkinje cell bodies.
6. It was concluded that the short latency response was due to activation via the mossy fibres and the longer latency response to activation via the climbing fibres.
7. It was found that responses could be evoked in the cerebellum following stimulation of only the latero-ventral part of the caudate nucleus; stimulation of the rest of the nucleus caused no response in the cerebellum. This division of the caudate nucleus into two parts is similar to the subdivision of the caudate nucleus made by other workers using different criteria.

TL;DR: The relationship between serial position and response latency in the learning and recall of short lists of letters was examined, with responses to the first and final positions being faster in general than to other positions.
Abstract: The relationship between serial position and response latency in the learning and recall of short lists of letters was examined. For a given length of list the relationship was non-linear, responses to the first and final positions being faster in general than to other positions. Response-latencies regardless of serial position tended to be longer for a seven-item list than for a five-item one. Rate-of-presentation was not a relevant variable within the limits of the experimental conditions employed.

TL;DR: Latency and rate of responding in the second component were facilitated by a 10 sec delay with respect to a 4 sec delay and the facilitation of response rate increased when the delay was increased to 50 sec.
Abstract: Operant responding of rats was delayed by withholding the response levers between the two components of a response chain. Latency and rate of responding in the second component were facilitated by a 10 sec delay with respect to a 4 sec delay. When the delay was increased to 50 sec. the facilitation of latency declined whereas the facilitation of response rate increased.

TL;DR: In both within- and between-Ss designs, the ready signal was shown to increase the frequency of short-latency eyelid responses, most of which are below the latency usually regarded as defining a CR.
Abstract: In both within- and between-Ss designs, the ready signal was shown to increase the frequency of short-latency eyelid responses, most of which are below the latency usually regarded as defining a CR. Since the occurrence of a short latency response sharply reduces the probability of a longer latency response, fewer responses are scored as CRs when a ready signal is used. These factors appear to explain the decrement obtained with a ready signal in eyelid conditioning.
