| 释义 | putamen noun[ C ] anatomy specializeduk /pjuːˈteɪ.mən/ us /pjuːˈteɪ.mɪn/pluralputaminauk /pjuːˈtæ.mɪn.ə/ us /pjuːˈtæ.mɪn.ə/ the outer layer of the lentiform nucleus(= part of the basal ganglia on each side of the brain that help control movement and emotion) that has a slightly red colour: The putamen is known to be involved in the perception of contempt and disgust, and may also be part of the motor system involved in movement and action. The image shows poorly defined putamina with an effaced grey–white matter contrast. Greater caudate and putamen activity suggest greater preparedness in response to anticipated positive events. For this type of learning, the critical structures are the posterior caudate, putamen, and the supplementary motor area. In the present study, hyperactivity of the left putamen was correlated with the excitement and disorganization symptoms.

The only difference was found in the selective activation of the left putamen. Studies of the caudate and putamen have yielded mixed results. The regions most sensitive to the mutation are the striatum, where there is typically 57% loss of cross-sectional area from the caudate nucleus and 65% loss of the putamen. Of special importance for him are the basal ganglia (the putamen, caudate nucleus, and palladium), which "are located deep in the cerebrum" and connect us to our reptilian past. These axons could be followed up to the border of the putamen, where the staining became too faint to allow the visualization of their terminal arborization. The putamen is the outer most portion of the basal ganglia. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Both regions acquire input from the putamen and caudate and communicate with the subthalamic nucleus. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. When a cell body of a neuron (in the putamen or caudate nuclei) fires an action potential, dopamine is released from the presynaptic terminal.

Isolated medium spiny neurons were stained, most intensely in the putamen, followed by the globus pallidus and caudate. Neural information transferred from the putamen to the globus pallidus during learned movement in the monkey. The most important structures within the basal ganglia are the caudate nucleus and the putamen (together referred to as the striatum or dorsal striatum) and the globus pallidus.
