Visual response characteristics of neuronal clusters in the caudate nucleus of behaving cats
Background: Anesthetized, paralyzed domestic cats are often used as model organisms in visual neu-rophysiology. However, in the last few decades, behaving animal models have gathered ground inneurophysiology, due to their advantages over anesthetized, paralyzed models.New Method: In the present study a new, behaving, awake feline model is described, which is suitable forchronic ...
متن کاملActivity of Caudate Nucleus Neurons in a Visual Fixation Paradigm in Behaving Cats
Beside its motor functions, the caudate nucleus (CN), the main input structure of the basal ganglia, is also sensitive to various sensory modalities. The goal of the present study was to investigate the effects of visual stimulation on the CN by using a behaving, head-restrained, eye movement-controlled feline model developed recently for this purpose. Extracellular multielectrode recordings we...
متن کاملSpectral receptive field properties of visually active neurons in the caudate nucleus.
Recent studies stress the importance of the caudate nucleus in visual information processing. Although the processing of moving visual signals depends upon the capability of a system to integrate spatial and temporal information, no study has investigated the spectral receptive field organization of the caudate nucleus neurons yet. Therefore, we tested caudate neurons of the feline brain by ext...
متن کاملThe firing rate of neurons in the nucleus cuneiformis in response to formalin in male rat
Introduction: Although formalin-induced activity in primary afferent fibers and spinal dorsal horn is well described, the midbrain neural basis underlying each phase of behavior in formalin test has not been clarified. The present study was designed to investigate the nucleus cuneiformis (CnF) neuronal responses during two phases after subcutaneous injection of formalin into the hind paw...
متن کاملResponse of caudate neurons to stimulation of intrinsic and peripheral afferents in normal, symptomatic, and recovered MPTP-treated cats.
Cat caudate nucleus (CD) neurons were tested for changes in spontaneous activity, response to peripheral sensory stimuli (tactile, auditory, and visual), and electrical stimulation of monosynaptic afferents (pericruciate cortex and nucleus centralis lateralis) in normal cats and in the same cats after induction of and spontaneous recovery from parkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-t...
