[Functional connections between the limbic cortex and caudate nucleus in young animals]

In anesthetized rabbits of 2-3-month age, stimulation of 24, 23, 29 limbic fields evoked potentials of the maximal amplitude in dorsomedial parts of the caudate nucleus ahead of the commissura anterior junction. Functional connections of anterior limbic cortex with the caudate nucleus are more obvious than these of posterior limbic cortical areas (23, 29). They occupied two medial thirds of the caudate nucleus. Short latency of the evoked potentials (4-5 msec) suggests that direct limbic cortex afferent connections of the caudate nucleus are well developed in 2-3-month old rabbits.
